German Motorcycle Helmets have a long history

The motorcycle was first developed for every day use in the military during WWII. Along with this development came a lot of the motorcycle gear and motorcycle apparel that enthusiasts still use to this day. One of these style are the German motorcycle helmets.

Fashioned after World War One and World War Two German Army battle helmets, the German motorcycle helmets do not stray far from the original design. There have been other helmet designs based on the original German motorcycle helmet, but this style remains true throughout time.
Being one of the most popular styles today as a motorcycle helmet, the German motorcycle helmet was once only available as a novelty item. It was something to set the extraordinary motorcycle rider apart from the rest of the crowd. Today, there are German motorcycle helmets, that have been approved by the D.O.T. for use in motorcycle riding.

There are no face shields for these types of helmet. They look a lot like the half shell of a turtle. The only other part that sets it apart from a turtle shell are it's colors and the chin strap. Black is a very popular color. Pink German motorcycle helmets can be purchased for the female motorcycle rider as well. Chrome German motorcycle helmets are available and add a certain flair to the helmet.

Carbon fiber German motorcycle helmets are very durable and have a resilience like no other. They can be covered with leather to give them a smooth and semi-glossy finish, as opposed to the shiny black that carbon fiber offers. These can also be adorned with flat black flames that offset the glossy black of the helmet.

When you are measuring for the size of a German motorcycle helmet, use a cloth tape measure. Consider having someone help you to do the measuring. This will ensure that you obtain an accurate measurement. Placing the tape measure about one inch above the eyebrows, and calculating the circumference of your head is the best way to find out the size that you would need. If the measurement falls between two sizes, choose the smaller size. Remember that the chin strap will also help adjust the fit for you as well.

As there are no face shields to the German motorcycle helmet, the motorcycle rider might want to purchase some motorcycle eye protection for their apparel. This is an absolute must on long road trips. The more popular options are yellow, gray, or clear blue tinted goggles. These use a strap around your head and are even more securely fastened in place by the chin strap feature of the German motorcycle helmets.

Whether you prefer leather, carbon fiber, chrome, or simply flat black flames, there is a German motorcycle helmet right for you. The sizes are plentiful, and the originality of the style ensures that you remain a part of motorcycle riding's great history. Purchase one today, and be sure to make the right call and buy the eye protection right for you.

Don’t Compromise On Motorcycle Racing Gear

The finest motorcycle racing gear is seen on the race tracks, and why not. The riders are aware of the dangers of skidding or colliding at high speeds, and take great precautions to protect their vital organs. Almost every accessory – from helmets to motorcycle boots – has extra protection.




The helmet is the most critical. You cannot sport a DOT certified helmet and hope to take part in a racing event. Almost every racing federation lays down the minimum rating that is acceptable. This rating is laid down by Snell Foundation, and is indicated on the inside of race helmets.

All riders ensure that the helmets they use fit snugly on their heads. There are no spaces between the cheeks and the padding. Most important, the helmet stays on the head, and does not roll off in case the bike skids or the rider hits an object.

It is equally important to have a clear view of the field. This involves not only a front view but also a side view. Often, riders get involved in an accident because the helmet walls reduce the side view.

The riders then need to protect their vulnerable parts like knees, elbows and shoulders. For this, they need specially designed racing suits that are made of thick leather and have heavy padding around elbows, shoulders, and knees. This armor is firmly sewn into the racing suit and does not slip off.

Another important requirement of racing suits is flexibility, especially in the arms and the shoulder region, not to mention the knees and the legs. These are the body parts that need highest flexibility, especially when the bike is in motion.

Equally important are the motorcycle boots. Almost every rider wears ankle-high boots because of the extra protection that these boots bring. These boots come with an extra lining, and have soles that are usually welded into the uppers so that they don’t fall away in case the rider drags his feet along the ground.

Another important part of a biker’s racing gear is gloves. These give the riders a proper grip, and help them manage throttle, clutch, brake, and turning operations smoothly. The racing gloves come with extra padding on the palms and finger backs to avoid bruising in case of a spill.

Every rider must ensure that they buy the best racing gear. It can make a big difference between life and death in case of an accident.

MotoGP Laguna Seca Results


Defending world champion Casey Stoner drove his Repsol Honda RC213V past Yamaha mullah Jorge Lorenzo into the lead on Lap 22 of the 2012 U.S. Grand Prix for a convincing and refreshing win, his third at Laguna Seca. This turn of events provided observers with a startling déjà vu of last year’s race. Stoner’s Honda teammate Dani Pedrosa finished third both years, adding the same eerie similarity to the podium celebration and post-race press conference.

I knew something weird was happening in Monterey when I glanced at the results of the first two practice sessions and noticed that the top five spots in each were identical. FP3 was mostly fogged out, and the Repsol Honda team blew it off in the garage playing euchre rather than tackling The Corkscrew blindfolded. Lorenzo snatched the pole from Stoner on the last lap of the QP, and then Stoner topped Lorenzo in the warm-up practice on Sunday morning by a full 1/1000th of a second, after waiting an hour for the fog to clear. Although the podium duplicated last year’s rostrum, the lead-up to the weekend was vastly different.

Recall last year. Heading to California, Stoner was enjoying a string of seven straight podium finishes, and led defending champion Lorenzo by 15 points. Lorenzo had been having a great season until he crashed out at Silverstone and finished a lowly sixth at Assen. Curiously, on Saturday Stoner had given himself virtually no chance of winning, all but conceding the round to his Alien rivals, a master class in sandbagging.

Despite having amassed a total of eight (8) points in the last two rounds and trailing Lorenzo by 37, Stoner started this weekend quick and got better each day. Curiously, he was the only one of the top six riders to choose the softer option rear tire on a day when the sun was quickly heating the racing surface. My thought was he would try to jump out to the lead and hope his tire held up long enough to fend off his challengers late in the race. And though he was able to go through on Pedrosa on lap 3, it took him 22 laps to pass Lorenzo. At that point I, for one, expected the Spaniard to win the race, thinking that his rear tire would outlast Stoner’s.

Wrong. The Australian did a masterful job managing his rubber, and still looked strong at the end of the day. Lorenzo, visibly exhausted after the race, didn’t have enough left in his tank to mount a serious rally at the end. Pedrosa observed after the race that the soft tire was too soft and the hard tire had no grip, and seemed pleased to have finished third.
When the tire dust cleared, the standings at the top of the 2012 chart had tightened slightly. Stoner became the first three-time winner at Laguna, where Hondas have won four of the eight races since 2005; it is inarguably a Honda-friendly layout. Lorenzo, with four consecutive poles but only one win, enjoys a larger lead leaving California than when he arrived. Pedrosa is, as yet, uninjured in 2012. Heading into the summer break, everyone has something they can feel good about.

Well, Not Exactly Everyone

Laguna Seca lived up to its reputation as a thorny place to ride motorcycles at high speeds. By lap 2, both CRT pilot Michele Pirro and Pramac Racing designated victim Toni Elias had crashed out. Two CRT pilots retired with mechanical problems or, more likely, Corkscrew-induced psychological issues, and James Ellison crashed on lap 20. None of these mishaps had anything to do with anything.
That would change on lap 22, when the luckless Ben Spies endured an ugly crash out of fourth place, ruining yet another weekend for the wayward American. Yamaha later attributed the crash to swingarm failure, the latest in a string of unfortunate circumstances for Spies this season. No one on the grid tries harder, or has less to show for his efforts. As the old blues standard laments, “If it wasn’t for bad luck, I wouldn’t have no luck at all.” Having injured his heel in a QP crash, Spies may have added to his medical woes ending his day with an Olympic-caliber double back flip in the tuck position, with a degree of difficulty of 4.3 out of 5.

The last and most surprising fall of the day occurred on lap 29, when Valentino Rossi, who never crashes, lost it at the top of the corkscrew for his first DNF of the season. We knew Rossi had a lot on his mind before the race, with the speculation about his future with Ducati and rumors of a return to the factory Yamaha team swirling. His Italian employers sent one of their Bigga Bosses to California to make The Doctor a final offer for next year, somewhere in the neighborhood of €17 million ($21 million) to waste another of the last few years of a great career wrestling the demonic Desmosedici. Vale didn’t appear to have much on his mind at all after the crash, wandering around in the gravel looking like he’d had his bell rung, waiting for his own personal fog to clear.

Elsewhere on the Grid

Tech 3 Yamaha teammates Andrea Dovizioso and Cal Crutchlow spent another lovely Sunday afternoon bashing each others’ brains in, finishing 4-5 for the fourth time this season. Nicky Hayden, glowing after having signed another one year contract with the Italian factory, went through on rookie Stefan Bradl late in the day to claim 6th place, relegating the German to a still respectable 7th in his first visit to Laguna.

San Carlo Honda’s Alvaro Bautista started 7th and finished 8th, another nondescript day at the office for the young Spaniard. Aleix Espargaro, clearly the cream of the CRT crop, finished ninth, with ”Kareless” Karel Abraham rounding out the top ten in his first return to action since Barcelona.


Bits and Pieces

The Hayden-Ducati marriage appears to work better for Nicky than for Ducati, as his best days are well behind him. Over the past three seasons he’s managed a single third place finish each year, and the last of his three (3) premier class wins came back in 2006, when he somehow won the world championship with a thin 252 points. (In 2008, Pedrosa would finish third with 249 points.) Other than name recognition, the Kentucky Kid doesn’t bring much to the party any more.

Rumor has it that Fausto Gresini, the volatile manager of the San Carlo team, is courting Andrea Dovizioso to return to the Honda family that so unceremoniously dumped him last year. Fausto has clearly lost whatever confidence he ever had in Bautista. Whether he can convince Dovizioso to wear Honda colors again is problematic. Personally, I think Dovizioso has earned the second factory Yamaha seat, and that Rossi could again be competitive on the factory-spec San Carlo Honda.An interesting bit of trivia concerns the Constructors Trophy awarded each year to the manufacturer whose riders earn the most points. Not surprisingly, Honda and Yamaha sit tied at the top of the pile. But third place Ducati is much closer points-wise to the Aprilia ART bikes than to the two Japanese manufacturers. We’ve come up with a term to describe the increasing irrelevance of the Ducati MotoGP program: Suzukification.

Honda Metropolitan

Honda believes it has the answer in the 2013 Metropolitan. Powered by a 50cc SOHC, two-valve, air-cooled four-stroke Single, the new version ditches the carburetor in favor of fuel injection. This makes for a reliable little scoot that meets future emissions regulations while gently sipping fuel: Honda estimates this setup can return 117 mpg! What is perhaps more noteworthy is its price. Coming in at $1999, it costs $50 less than its predecessor when it was last imported to the U.S. in 2009. This is achieved utilizing Honda’s China manufacturing plant to build this worldwide model instead of building in Japan as before.

Nevertheless, build quality is typical Honda: solid, with everything fitting as they should with no loose pieces or exposed wiring.

The 2013 Metro also sees all-new styling, highlighted by a new headlight and gauge setup, different handlebar, and a new taillight assembly. Truth be told, the new model doesn’t look vastly different than the old one, but diehard Metro heads will be able to tell the difference.

From the cockpit, the rider is still graced with a 22-liter under seat storage area big enough to stuff a three-quarter helmet. A new inner storage unit incorporated within the leg shield has ample room for a number of items, including a water bottle. A larger convenience hook has also been added to help bring home groceries.

The Metropolitan stakes its claim in the scooter world for being easy, gentle and inviting. With a listed curb weight of 179 pounds, 28.3-inch seat height and 46.5-inch wheelbase, the little scoot isn’t the least bit intimidating.

However, once on the road one can’t help but feel vulnerable to the traffic around you. The Metropolitan tops out at just 40 mph and doesn’t get there quickly. There’s only so much power that can be expected from an EPA-legal 50cc engine. Throttle response is relatively sprightly, with smooth fueling from idle throughout the rev range, feeling on par, if not slightly less powerful, than the Yamaha Zuma 50F I rode a few months ago. Off-the-line torque felt better on the Yamaha, but I would give the top speed advantage to the Honda, according to my seat-of-the-pants dyno.

A continuously variable transmission handles “shifting” duties, leaving the rider free to simply twist and go. Despite its small stature, comfort is fairly decent as well. The large seat has ample padding and leaves enough room for riders to scoot back and stretch out a bit. There’s plenty of space in the footwell for large kicks as well.



Bumps in the road are absorbed by a twin-downtube fork and single shock with 2.1 inches and 2.3 inches of travel, respectively. Ten-inch wheels are fitted to each end. The ride is relatively comfortable over most surfaces, despite the meager components. Poorly maintained roads or big pot holes do tend to bottom the suspension.

The only chink in an otherwise impressive armor are the brakes. The Metropolitan is still equipped with drum brakes at each end, with the rear linked to front. Stopping power when using both brakes is quite good but drops dramatically if only using the front binder.

Still, for a scoot that comes in under two grand, there’s little to complain about. Our ride route saw plenty of open stretches of tarmac and prolonged wide-open-throttle opportunities. Despite my shenanigans, the fuel gauge moved just a tick. While our experience has shown scooters to miss their advertised mileage claims, under normal, sensible, riding conditions the Metropolitan should return impressive numbers.
In the 50cc, retro-styled scooter market, it’s hard to find a competitor that delivers more bang for the buck. Yamaha’s Vino offers similar specs and styling but is carbureted, delivers worse (claimed) mileage, costs $251 more, and most importantly, isn’t listed as a 2012 model in Yamaha’s scooter lineup – good luck finding a new one in dealers.

The only other 50cc Japanese scooter with EFI is the recently launched Zuma 50F, also from Yamaha. Top speeds are almost identical, and the Zuma holds a 1-liter advantage in storage capacity, but the Yamaha really stands out for its rugged and off-roady appearance. The Zuma benefits from a front disc brake that’s much better than the Metro’s front drum brake, and its 132-mpg claim trumps the Honda’s, but real world numbers always vary greatly. Most importantly, the Zuma costs $2540 compared to the Metro’s $1999 – that’s a big difference for the cash-strapped student deciding between the two.

European scoots can’t match the Honda’s pricepoint either. You’ll have to look to Taiwan to find comparable challengers for the Metro. Kymco’s Sento 50 is equally priced to the Honda but is carbureted and can’t match the Honda’s mileage numbers. Not to mention, when it comes to build quality, reliability and dealer networks, Honda’s reputation is second to none.

WIth the new Metropolitan, Honda delivers a reliable, practical and economical mode of transportation perfect for downtown dwellers. All for under two large. And in some states, you don’t even need a motorcycle license to ride one. If you live in a big city and are tired of walking or taking the subway, the Metropolitan deserves a look.

BMW reworks the S1000RR


We were mightily impressed by BMW's S1000RR superbike the first time round, now the German manufacturer has announced the S1000RR mark II. Power and maximum torque figures remain at 142 kW (193 hp) and 112 Nm on the revised superbike with the mostly subtle changes centered on improving response, power delivery and handling. The torque curve, throttle response and suspension have all been tweaked along with the (very effective) ABS and Dynamic Traction Control systems. Externally, the 2012 SS1000RR gets an upgraded instrument cluster, revised rear-end, redesigned side panels with the addition of two winglets for improved aerodynamics and a new range of colors.

The S 1000 RR has has wasted no time populating the trophy cabinet since its release in 2009, winning 13 titles and over 120 race victories in superstock and superbike championships during its first full year of competition. BMW Motorrad, which offers a support service to customers who want take the S1000RR racing, says feedback from the track played a major role in the bike's overhaul.

"We listen very closely to our racing colleagues in many teams, especially the BMW Motorrad Italia superstock team or the IDM Team BMW Motorrad Wilbers Suspension," said RR Product Manager Sepp Mächler." We help these teams out and they give us quick and reliable feedback, which helps reduce development times."

Here's a run down on the key changes:
  • reconfigured throttle with 25% less twisting force and tighter twistgrip for improved response
  • more linear torque curve and expansion from two to three performance curves (one each for Rain and Sport modes and an additional one for Race and Slick modes); Rain mode now 120 kW (163 hp)
  • enhanced tuning between Race ABS and Dynamic Traction Control (DTC)
  • final drive now 17/45 (was 17/44)
  • modified steering head angle, swing arm pivot position, fork projection, and rear shock absorber length
  • new internal structure for upside down fork and the rear shock absorber
  • new mechanical steering damper adjustable over ten levels
  • leaner tail section, modified stainless steel exhaust system, larger intake air guide, redesigned side panels, side aperture grilles and winglets
  • revised LCD instrument cluster easier to read rev counter, five dimming levels and additional functions such as "Best lap in progress" and "Speedwarning"
  • revised RR logo
  • new color variants: plain Racing Red with Alpine white, Bluefire, Sapphire black metallic, BMW Motorrad Motorsport
The revised BMW S1000RR was shown this month at EICMA in Italy and is set for release in January 2012. No RRP has been announced as yet.

NeilPryde Bayamo bicycle targets time trial riders and triathletes

The partnership between BMW's DesignworksUSA and NeilPryde that began in 2010 with the Alize and Diablo high performance road bikes has yielded its latest design. The third line of frames resulting from the partnership are the new Bayamo and Bayamo+, which take on board concepts developed and tested on the earlier models. Aimed at time trial athletes and triathletes, their creators say the bikes are lightweight and high strength, with “wind-cheating aerodynamics.”

Named after a Caribbean coastal wind, the Bayamo’s unidirectional C6.7 carbon fiber frame is the result of computational fluid dynamic analysis and wind tunnel testing. Side on, the frame appears quite substantial, but it is revealed to be exceptionally thin when viewed front on. This is to minimize wind resistance and increase aerodynamic performance for time-trial cyclists for whom every split second counts. The “Kamm” tail aerofoil found on previous models has been truncated to deal with the wider yaw angles of up to 30-degrees experienced during time trials and triathlons.

Further enhancing the bike’s clean lines are the routing of all the drivetrain and shifting cables inside the Bayamo’s frame. The bikes also get an exclusive dropout mechanism that it is claimed enables precise positioning of the rear wheel, while the Bayamo+ gets a new proprietary QFit stem design that is adjustable for both height and ride angle. The maker’s say the bottom bracket where the cranks and pedals meet the frame has also been made exceptionally stiff to ensure the rider’s energy is more efficiently transferred.

The Bayamo frameset, including frame, forks, seat post, and headset, is available now for US$2,750, while the Bayamo+ frameset, which adds the QFit stem and fully integrated brakes, will be available in 2013 for $5,000. Adding a Shimano groupset, Mavic wheel, and other premium components sees the prices rise to the $3,095 to $10,000 range.

Zero S and DS

Starting with the S and DS models, changes include new bodywork as part of a facelift to give each machine more attitude. Both models also get integrated storage compartments in place of a traditional fuel tank. The saddle now forms into a two-tier design to accommodate both rider and pillion more comfortably. The seat height of the S is a reasonable 31.3 inches, vaulted up to 34.4 inches on the DS due to its long-travel suspension.

There are still two power pack options like last year, though instead of 6 kWh and 9 kWh packs, both options have increased in capacity to 8.5 kWh and 11.4 kWh. Zero claims the motors crank out 54 horsepower and 68 ft.-lbs. of torque, and can reach a top speed of 95 mph. The main differences are price, weight and mileage.

 
The S model with smaller ZF8.5 power pack retails for $13,995, weighs 350 pounds and has an estimated range of 103 miles city, 53 highway and 70 combined. With the ZF11.4 power pack, price jumps to $15,995, weight to 382 pounds and mileage to 137 city, 70 highway, 93 combined.

Though prices for S and DS models are the same, the latter sees slightly lower mileage figures due to the higher rolling resistance of its knobby tires and its taller aerodynamic profile. Owners of the 363-pound DS ZF8.5 can expect to see mileage figures around 95 city, 46 highway and 62 combined. ZF11.4 numbers come out to 126 city, 61 highway and 82 combined for the 395-pound motorcycle.

S models will be available in either black or yellow, DS models in orange or green.

Behind the scenes with the Pirelli Tire Men

Motor racing in the premier categories has always attracted not only the bravest and most skilled performers in the physical sense, but also the best and brightest thinkers – engineers and technicians who are responsible for what those elite athletes are riding on, in every sense of the term. But thankfully things have moved on from Pirelli's secret midnight raids of the 1980's where they would, under the cover of darkness, sneak onto a F1 circuit to dig up a section of track so that their developers could take it back to the lab for examination, as Pirelli Moto Racing Director Giorgio Barbier concedes with a hearty chuckle.

In the 1980's, Pirelli racing tire development was geared towards ultimate performance for F1, rally and the new motorcycle racing premier categories. The task then was to provide winning tires for winning teams regardless of the cost or how exotic the construction technology or rubber compounds got. Pirelli followed the tried and true "win on Sunday, sell on Monday" promotional and advertising brand image model to which so many of the racing manufacturers subscribed – and still do.

These days the focus for motorcycle tires has changed. According to Barbier and racing compound development engineer, Fabio Meni, with whom we talked at Phillip Island recently for the first round of the WSBK 2012 season, now Pirelli's job as the chosen control tire manufacturer for WSBK is one of finding a motorcycle racing tire that will perform in a far broader range of conditions, and one that any sportsbike owner can then buy off the shelf. A compromise which reflects the rules of the production based category, and one that anyone riding from the public roads to a track day on their own bike shod with road tires will appreciate! And be aware that a WSBK pole sitter is now also quick enough to qualify on the front rows of a MotoGP grid, which means that engineering technology has found the ultimate limits of speed in even mass produced motorcycle manufacturing and no small measure of that is down to the tires.

Phillip Island has it's own unique place on the WSBK racing calendar for a few reasons. Not only is it the first meeting of the season - which means the uncertainty of rusty riders and teams using new, un-raced technology - but it is also the fastest circuit on the schedule with the most sunshine (UV), so potentially the hottest air and track surface temperatures. A confounding mix of variables for even the most astute competitors … there must be something about jumping in the deep end in Australia for Pirelli it seems, as Melbourne's Albert Park has also hosted the F1 (another Pirelli "client") opening round for the past eighteen years.

Maintaining tire performance or, more simply, grip, over time with an ever increasing range of variables has made the job of manufacturing them on a large scale more tricky and involved than it's ever been. And when you consider that tire grip is the most critical single factor influencing a road vehicle's performance, then you'll understand how important the job is.

For example, did you know that the molecular structure of a soft compound racing tire when cold is stiffer than that of a much harder one? So different before it reaches operating temperature, in fact, that under a microscope it actually resembles glass more than rubber. That's right, glass. It means that that heart-in-mouth first corner of the race is actually even scarier than it looks – if that's indeed possible!

The future of the motorcycle tire market is, as you would expect, throwing up wildly different technological challenges, not least of which is electrically powered sportsbikes. Just as Yamaha recently modified the crankshaft angles and firing order of their in-line four to enable better tire performance by letting the compound "cool down" in the nanoseconds between combustion pulses, the constant power delivery of electric motors will benefit from a close partnership with the tire manufacturers to steer their development at the sports end of the market.

For an explanation in more wonderful detail of their fascinating job, watch the full in-depth interview with Giorgio and Fabio below, but be warned, it goes for almost half an hour.Motor racing in the premier categories has always attracted not only the bravest and most skilled performers in the physical sense, but also the best and brightest thinkers – engineers and technicians who are responsible for what those elite athletes are riding on, in every sense of the term.

Ninjapalooza

The Pearl Stardust White EX650 and Passion Red ZX-10R stood out like fishing bobbers adrift on a Lime Green sea of corporate-branded Ninjas. However similar in color, the 20 or so Kawasaki sportbikes, representing the performance spectrum from 300cc to 1000cc, assembled in the Chuckwalla Raceway paddock, is an impressive sight, warming the heart of this chilled moto-journalist on a frigid January morning in the high desert.

Commonly, track shootouts pit motorcycles of generally equal performance against one another to determine a superior model if only by the slightest advantage. This Kawasaki sponsored event, however, provided an opportunity for riding models of disparate calibers in a consecutive sequence of my choosing. A half-hour session aboard the new-for-2013 Ninja 300 followed by a stint on the potent ZX-10R, sure, why not? Mix in some sessions with the reintroduced Ninja 636 and its more utilitarian counterpart, the Ninja 650, and the performance potpourri is complete.

2013 Kawasaki Ninja Fleet

Missing from the Ninja-fest is the Z1000 and ZX-14R. While the Z1000 would certainly be a fun bike on which to navigate Chuckwalla Raceway, the world’s fastest production bike is better suited for illegal top speed runs on the nearby Interstate 10.

To encourage steep lean angles and aggressive riding, Kawasaki shod the participating Ninjas with some stickier-than-stock Bridgestone rubber then ushered riders onto the track, in counter-clockwise fashion, which, as of now, is my preferred direction of travel at this particular venue.

While circulating the 17-turn, 2.7-mile-long track I was both the passer and passee. Oftentimes I was aboard the underpowered Ninja 300 or Ninja 650 going up the inside or around the outside of a lesser skilled rider piloting a more potent machine such as a 636 or even a 10R.

2013 Kawasaki Ninja 300 Track

The Ninja 300 doesn’t look like a “beginner bike.” Maintaining high corner speeds is requisite to setting fast laps times on the littlest Ninja, and its 379-pound wet weight begs you to toss it into corners with abandon. Low stock footpegs hamper higher corner speeds but are easily replaced.

I’m not being smug, simply pointing out (even to my surprise) how effective a motorcycle unendowed with the latest technological go-fast doohickeys can be. Left knee on the deck, footpeg grinding against the asphalt, arching a tighter line through Chuckwalla’s long, sweeping Turn 5 and beneath the person riding higher up the corner’s 10 degrees of banking speaks more to capabilities of the Ninja 300 than it does my riding prowess.

2013 Kawasaki Ninja 650 Action

The 2013 Ninja 650’s parallel Twin thumps out enough power to keep things interesting. Its open seating position allows for easy movement when transitioning from side to side. The higher, superbikesque handlebars are somewhat awkward but you get used to them.

When I was passed while aboard the 300 or 650 it was evident that cornering speeds between the pedestrian and supersport models are incredibly similar (a testament to the ability of quality tires to up your game). The more powerful bikes left the diminutive Ninjas inhaling exhaust fumes on corner exits but for a few brief seconds, at the corner’s apex, the 300 and 650 Ninjas were equal to their supersport superiors.

Whereas the 300’s throttle remains pinned 98% of each lap, the Ninja 650 outputs enough rear-wheel horsepower to require some throttle manipulation lest you spin the rear into oblivion getting on the gas too forcefully while at full lean. When this happened to me while cresting Turn 9 it reignited long-dormant riding tactics. Soon thereafter I was clicking off downshifts while hard on the brakes dumping the clutch and enjoying the resultant hopping and squirming of the 650’s rear end – common to hard riding a bike sans a slipper clutch.

2013 Kawasaki Ninja ZX-6R Action Front

As smooth as you like, the 636 Ninja enters and exits corners with poise and agility. The bike’s slipper clutch and traction control technologies reduce the effects of sloppy downshifting and excessive throttle application, allowing a rider to focus more on corner entry and exits points and cornering speed.

No such antics on the technologically advanced Ninja 636. While some lament the intrusion of rider aids it was never more apparent than when swapping the Ninja 650 for the 636, or especially the ZX-10R, that traction control, slipper clutches, ride modes and other technologies go a long way into sweetening the supersport experience.

With the performance of modern sportbikes outstripping the abilities of most riders, these electronic mechanisms allow motorcyclists to more safely explore, and sometimes go beyond, their personal limitations. Pushing the envelope on a bike as effortless as the ZX-6R is reasonably manageable, whereas a literbike is constantly provoking a rider to explore his or her subjective performance thresholds.

On a tight track like Chuckwalla, where the longest straight is a mere quarter of a mile, the Kawasaki ZX-10R is, to state the obvious, a challenge to control. Incredible speeds are realized in the short distances between corners demanding more braking and often inciting over-braking resulting in slower corner speeds. On fast tracks such as Willow Springs, literbikes get to stretch their legs and put their monstrous horsepower to work, but such wanton performance can overwhelm both rider skill and technological safeguards.

2013 Kawasaki Ninja ZX-10R Action

Compared to the other Ninjas at Chuckwalla the ZX-10R is mind-numblingly fast. It tears your arms out of their sockets accelerating out of a turn before nearly pitching you over the windscreen when slowing for the next rapidly approaching corner.

For testing my mettle, the 10R is certainly the measuring stick of choice among Ninjas. But the physically exhausting nature and mental depletion during such an activity can only be safely tolerated for short durations.

I found the rare experience of piloting the 300 and 650 Ninjas around a track to be enticingly fun and challenging without the fear the 10R injects into the situation. But, given a choice I prefer the performance a mid-displacement bike, such as the Ninja 636, has to offer.

2013 Kawasaki Ninja ZX-6R Action Left

The combination of fun and thrills are nicely balanced in the ZX-6R. If I were Goldilocks and where the Ninja 300 and 650 are too slow while the ZX-10R is too fast, the Ninja 636 would be just right.

What this all stands to confirm is the age-old expression that it’s better (funner?) to ride a slow bike fast than it is to ride a fast bike slow. You can also add to that the self satisfaction of passing a faster bike with a slower one – that’s like bringing a knife to a gunfight and winning.

BMW K1600GTL Review

In the day prior to riding the K1600 super tourer in South Africa, I had several opportunities to ask BMW engineers questions about how it compares with Honda’s Gold Wing, a veritable icon of the luxury-touring class.

“No, this isn’t like a Gold Wing,” they’d say. In fact, the GL1800 BMW last had for comparative purposes was several years old, and they couldn’t recall the last time anyone had ridden it.

But how could BMW not benchmark the segment’s class leader?

Both the GTL and the GL have luxurious accommodations, six-cylinder engines twisting power through a driveshaft, considerable luggage space and excellent wind protection from encompassing fairings.

Outward similarities aside, BMW Motorrad General Director Hendrik von Kuenheim flatly denies the Gold Wing was the target. Rather than building a luxury-tourer like the Wing, the blunt yet exceptionally affable chief tasked his engineers with creating a “supreme” tourer with greater sporting intent. After all, he adds, the touring market is “the domain of BMW.”

The K1600GTL (and its sportier twin brother GT, to have its own review in a few weeks) is a clean-sheet design that boasts a plethora of desirable standard and optional equipment.

And what do these have in common? None are available on the long-in-the-tooth GL1800 Gold Wing, which debuted way back in 2001.  Although the GL receives minor revisions for the 2012 model year, we’re still waiting on the ability to adjust the height of its windshield with a button, a device now nearly ubiquitous among bikes with a serious touring intent.

At one time we bought into Honda’s logic that an electric motor to raise the GL’s screen (it’s manually adjustable for height) would add unnecessary weight, but the K1600 proves the two aren’t mutually exclusive. The Honda scales in at more than 900 lbs full of fuel, while the GTL is a relative flyweight at 767 lbs. (Incredibly, BMW says the K16-GTL is lighter than the former K1200LT by more than 110 lbs!)

Devotees of old Goldie might decry this comparison as unfair since the 1832cc flat-Six Honda is in a different displacement class than the 1649cc inline-Six BMW. But if that’s the yardstick, then the GTL punches easily above its weight. Its undersquare (and, hence, relatively narrow) mill churns out a purported 129 ft-lb of torque at 5250 rpm, reaching a crescendo of 160 horses at its 7750-rpm peak. That should translate to 135 hp at its 190/55-17 rear tire, almost 40 ponies more than the Honda.

Sing, Sing A Song

Simply put, this is one of the most sonorous streetbike engines ever made. It lights up with a bark that portends wicked things to come, and despite its long-stroke architecture, it spins up far quicker than expected for a touring bike’s motor.

2012 BMW K1600GTL

The 1649cc inline-Six in the GTL has instantly become one of our favorite engines of all time. It packs big power and is incredibly smooth and sweet-sounding.

But the really unexpected payoff occurs when the loud handle is twisted hard, as the exhaust note crawls over itself like the best sporty I-6s do – think a miniature Jaguar or, of course, a BMW car engine after inhaling a whiff of helium. It whoops rapturously after 6500 rpm, especially when intake honk at full throttle is added, deliciously so when the delicate yet angry note is bouncing off canyon walls back into its smiling pilot’s ears.

And it also functions perfectly. Throttle response has zero abruptness, even on the most aggressive “Dynamic” riding mode (also adjustable between Rain and Road modes via the right-side switchgear or multi-controller). And there are no issues with excess engine heat like some other big-engined tourers.

Also impressive is the liquidy smoothness of the engine itself, as I-6s always are with their naturally balanced primary and secondary forces. There is only the faintest of vibes filtering to the rider at any speed, and the engine is so smooth motoring at 100 mph in top (sixth) gear that it can also easily cruise at that speed in fifth without bothering its rider.

In the inevitable comparison with the Honda, the GL does seem to have a bit of an advantage when revs are below around 2500 rpm, but the K16 likely out-thrusts the Wing everywhere else. Speed demons will be happy to know there is enough power on tap to exceed 140 mph, and the aluminum bridge chassis has the requisite stability to ably handle it.

When not racing Hondas, the K16 mill functions admirably in its civilized street role. Although its clutch engages near the end of its travel, it still modulates easily when balanced against its deep well of power. And its gearbox is exemplary – we never missed a shift during two days of riding, and it accepts upshifts even without a clutch. Neutral is easy to locate.

Despite its visual bulk, the K1600 GTL has surprising agility.

We’ve always admired the Gold Wing for its ability to be hustled through curves with alacrity that belied its considerable size, but the K1600 series brings the big-boned dancing partner to a new level of agility. It’s amazingly flickable. Yes, I said flickable. It turns in neutrally and continues through a lean angle that would make a Wing-er envious – the Beemer is the easy racetrack winner if you were ambitious enough to bring these mega-baggers to a track.

The GTL is guided by a Duolever front end borrowed from the now-defunct K1300GT, and it works really well in this application. Steering effort is much lighter than expected, and partial credit is due to excellent new Metzeler Z8s that were developed in conjunction with the K16. The Duo’s design naturally limits fork dive under hard braking while not feeling entirely disconnected from the front axle.

Not Your Dad’s Suspenders

Bump absorption is provided by just a pair of hydraulic dampers, one in the Duolever up front and one in the Paralever rear. The GTL’s Premium Package (a $2645 upcharge over the base $23,200 MSRP) includes BMW’s sweet ESA II suspension that enables suspension adjustments at the touch of a button. In addition to Comfort, Normal and Sport, ESA also provides additional settings dependent on loads, i.e. luggage and passenger weight.

ESA is a boon for any type of bike, and it’s even more valuable on a touring machine that is likely to travel over nearly every type of road. It’s a wonderful thing to be riding a sinuous mountain road in buttoned-down Sport mode, then flip it over to Comfort when the twisties become a freeway. We didn’t get a chance to sample the base suspension, but we were really impressed with the alternative setups of the GTL’s ESA, providing firm response when needed, then plushness when comfort becomes the priority.

Smart Retardation

The GTL proves to be up to the task of slowing down 900-plus pounds of bike and rider, as it uses a potent triple-disc combination of brakes with BMW’s part-integral ABS as standard equipment. Forget the old concerns about antilock and linked brakes, as this thoroughly modern set performs seamlessly, even when mauling the dual 4-piston calipers up front and 2-piston rear.

Feel from both ends is solid and precise, and souring ABS feedback is almost non-existent even with tires howling. As for the linked component, it works so well that I completely forgot they were even coupled. This is an excellent system with the safety benefit of ABS. Trail braking does nothing to upset the chassis or cause the bike to stand up and alter its line.

The chrome pieces above the BMW roundel can be flipped outward to direct cooking air to the rider.

BMW has three wind tunnels, so it’s not surprising that the GTL has well-developed aerodynamics. Its windscreen is a big one, with the added benefit of height adjustability over a vast range. At 5-foot-8, my eyes are just below the upper edge at its lowest level. Taller riders can see over it but experience slight turbulence unless it is raised slightly. Riders of all sizes are sheltered when the screen is at its highest position – its coverage is incredibly encompassing.

In hot conditions, a rider can dramatically alter the airflow by using innovative flip-out vents on either side of the fairing. BMW calls the section below the nose fairing and above the upper side fairings an air channel, and the chrome pieces between them can be manually flipped outward to grab oncoming air and send it at the rider. By redirecting airflow along this key channel, it completely alters the stream of air swirling around a rider and brings cooling relief. Very simple yet extremely effective.

The GTL’s riding position is very hospitable.

Built to cover long distances in comfort, the GTL is set up with a perfectly neutral riding position. The handlebars are set right where your hands naturally fall, and feet are positioned just slightly forward of a rider’s butt. Our test bike was fitted with the optional low seat placed at just 29.5 inches. This makes the GTL easy to manage during low-speed maneuvers, but tall riders likely will prefer the standard 30.7-inch seat for long days in the wide and supportive saddle. The fuel tank is narrow between the knees despite its considerable 7.0-gallon capacity.

Handlebar controls are thoughtfully arranged, starting with finely adjustable levers. The turn signals are now triggered by a traditional single switch on the left handlebar, augmented with an effective self-canceling program. Standard cruise control is operated via buttons on the left bar, and the system is very well controlled

An array of other features – including heated grips and seat, ESA and audio functions – can be set by BMW’s inventive multi controller. The MC is a knurled wheel that rotates around the left handlebar and can be toggled in two directions to select different settings that show up on the easily read 5.7-inch TFT (Thin Film Transistor) color display panel. The MC wheel is intuitive and has a nicely damped and expensive feeling, although it does make the reach to the turn-signal switch slightly longer.

BMW’s Multi Controller wheel augments switchgear for cruise control and power windscreen.

As a high-end touring rig, the GTL is fitted with a surfeit of convenience features. Standard equipment includes heated seats and grips to five levels, cruise control and ABS. Ample luggage space is provided by saddlebags and a top box, each detachable unlike the Wing – the GTL has nearly 470 lbs of available payload capacity. Xenon headlights have a self-leveling feature.

“The world’s most advanced audio and communications system on a motorcycle” includes satellite radio and an MP3 player, all of which can be manipulated by the Multi Controller. The audio system can also be directed via Bluetoooth connectivity so that audio can be sent wirelessly to a communicator system like the BMW unit in the Schuberth helmet we were provided; otherwise, sound is sent to four cockpit-mounted speakers.

The GTL’s cockpit is premium quality and provides loads of info.

The aforementioned Premium Package brings a new level of equipment to motorcycles. The luxury component includes ESA II, an alarm and a central locking system, the latter not easy to do with removable bags - it uses the same components as BMW cars and makes an identical satisfying “schlup” sound.

The safety elements of the high-end package consist of gyro-fed traction control, a tire-pressure-monitoring system and the world’s first adaptive headlight fitted to a motorcycle. The innovative headlight uses a servo-equipped mirror to direct the headlight beam in the direction of travel, even around corners. Although we didn’t do any night riding, a table-mounted simulator convinced us of its efficacy, and it will surely be a real benefit to night riders.

The GTL comes prewired for BMW’s Garmin-built Navigator IV, but it’s available only separately from your dealer for around $850. The Nav IV simply drops in to a built-in cradle and it’s instantly integrated into the GTL’s system, even its Bluetooth arrangement. The nav screen is up high and visible, and it’s cleverly secured in place by the windshield in its low position.

BMW’s Adaptive Headlight cleverly pivots the beam around corners and eliminates the dipped lighting when leaned over.

Passenger comfort would be better if the seat was extended further rearward.
2012 BMW K1600GTL

Grab rail access is hindered by the seat’s outer edge.

The GTL does have one significant foible: passenger accommodations fall way short of the Gold Wing’s. Good comfort exists when a pillion is resting his/her hands on a rider’s waist, with abundant legroom up to the wide and comfy seat. A backrest integrated on the top box provides welcome security.

However, the amount of fore/aft room is somewhat limited. Sitting far back on the seat for the most room, your butt is positioned on the transition from the seat to the nylon box mount, making it feel like you’re sitting in a crevice.

Things fall apart further while riding at a brisk pace when your pillion will want to grip the hand rails. There isn’t sufficient room between the seat edges and the rails to comfortably fit in gloved fingers. And when you do jam them in, the backrest wings awkwardly force the bicep area forward. To riders who frequently travel two-up, this could be a deal breaker, depending on the size of your passenger.

Searching for more nits to pick, the gap between tank and seat is a trifle gauche in light of the otherwise excellent fit and finish of this super tourer built in Berlin. Lastly, the GTL we rode emitted an annoying primary-drive gear whine from 1700 to 2200 rpm, but that seemed to be atypical compared to other K1600s at the launch – the mechanically identical GT I rode was quieter by about 50%. The K16s at the press launch were pre-series production bikes, and BMW engineers note that production bikes will have some adjustment of tolerances that should keep whining to a minimum.

The Verdict

To say we were impressed with the K1600 (including the GT version) is a colossal understatement. Blown away is more like it.

Its six-cylinder engine is sex on wheels with power to spare. Its agility and athleticism is positively shocking for such a big girl, and its suspension and brakes are best in class. What’s more, its array of standard and optional equipment put it in a league of its own. And, at $25,845 for the GTL’s Premium Package, it compares very favorably to a loaded Gold Wing ($27,099) mildly revised for 2012.

The venerable Gold Wing still holds a clear superiority in passenger accommodations and a slight advantage in ultra-low-speed handling, but the K1600 GTL otherwise significantly advances the super-touring category in every other way possible.

Kawasaki ZX-14R


Let there be no doubt the ZX-14R is a special motorcycle. It’s the quickest accelerating production vehicle in the world, able to dust off even a 1200-hp Bugatti Veyron Super Sport down a dragstrip. The $2.7 million Veyron takes 9.9 seconds to get through the quarter-mile sprint, according to Road & Track. In our testing, a bone-stock 14R shredded the strip in a paltry 9.36 seconds. And keep in mind that, at $14,699, you could nearly buy three ZXs for the price of just one set of the Veyron’s tires!

But the ZX-14R is more than a one-trick pony. For a record-setting speed king, the biggest Ninja can be an astoundingly docile tool when dealing with everyday traffic situations. Throttle response is silky, and its agility is excellent for a bike of its 540-pound (tank-empty) size. And on the highway, the 14R becomes the world’s fastest sport-tourer, gliding serenely through

the air with only a whisper of vibration from the 188-hp engine. Your only concern will be where to pack your clothes. Add a traction-control system that’s smart enough for a dragstrip and can be switched off if you dare, and you’ve got one of the most impressive motorcycles we’ve ever ridden.

Soon you’ll be able to read our shootout between the ZX-14R and Suzuki’s Hayabusa, so you’ll have to stay tuned to find out exactly how this duo compares and what sets them apart from each other. But now you already know the outcome…

Kawasaki Ninja 250R Review

But then, does Kawasaki’s Ninja 250R even need an introduction? Since receiving a stylistic and functional makeover in 2008, which you can read about here, the Ninja has continued its legacy as a top seller for Team Green.

To those of us who’ve known this little screamer for a while now, it’s not a mystery. Perhaps the only mystery in our minds is why the other Japanese OEMs have been content to let Kawasaki own this segment for the past couple of decades or more, but we’ll save that for the sidebar.

For those of you who need a refresher, here goes:

The Numbers

Motivated by a smooth-running DOHC 249cc parallel-Twin pushing a peak of 25.4 hp to the rear wheel, this 374-lb machine offers enough power to stay ahead of around-town and suburban traffic, and will top out around an indicated 100 mph or so.

Its twin Keihin constant-velocity carburetors aren’t as sophisticated as the fuel-injection on the Euro version, and the twin carbs are jetted lean to pass emissions regs. This results in an engine that needs to be warmed up before it’s able to be ridden away, and low-end throttle response is a bit soggy.

“It’s definitely on the lean side in the low end and midrange,” says Kerry Bryant, who has tuned many Ninja 250s as owner of Area P, a SoCal-based shop that also manufactures exhaust systems. “Changing/adjusting the jetting can make a dramatic improvement in throttle response, even with the OEM exhaust system.”

Once warmed up after a few minutes, the machine will accelerate from a standstill with the revs at around 3,000 rpm while slipping the clutch. Carburetor tuning is not a pre-requisite, but to make it run the way it could, it is something we would do.

For optimum performance, Bryant recommends a Dynojet kit. Short of this, improvement could be had by simply adjusting the fuel mixture screws to see how that works first. This tweak can be done by a qualified technician, or competent do-it-yourselfers and can be discussed with a dealer’s service department.

“Adjustments depend on elevation, temp and humidity (and of course other mods made to the bike such as aftermarket exhaust, airbox, etc.),” Bryant elaborates for those wanting to fully tune their Ninjas. “For our particular location and conditions, adjusting the fuel mixture screws out 2.5 - 3.0 turns (from bottom out) improves the low-end. Replacing the needles with a different taper and adjustable clips will improve the mid-range. Main jet size normally ends up being #98 (Dynojet [brand] jet kit sizes/numbers and not to be confused with the OEM Keihin sizes/numbers).”

With a jet kit installed, Bryant says, “The primary difference a street rider will notice is throttle response more than anything else. It will now feel like your right hand actually controls and modulates the power input like it should be.”

In stock trim, the liquid-cooled mill is reliable and quick. Although the power delivery is soft off the bottom and requires some clutch slipping, it responds with enthusiasm once past 8,000 rpm until 11,500 rpm when power begins tapering off before hitting the 13,000-rpm rev limit. A brisk pace requires gear changes to its six-speed transmission at short intervals.

The powerplant rolls within a steel diamond-style frame, utilizing Kawasaki’s Uni-Trak rear suspension with five-position preload, in conjunction with a 37mm telescopic fork canted at a stable yet nimble 26 degrees rake, and 3.2 inches trail.

Slowing it all down are brakes that are reliable and drama-free. A single 290mm front rotor clamped by a twin-piston caliper does most of the work, with the 220mm rear and twin-piston caliper rear there for backup.

Its Purpose

The Ninja 250R’s aerodynamic bodywork and styling looks remarkably similar to the ZX-6R and ZX-10R, and that is purely not coincidental. There’s no “250” emblem on this big little 250, and that’s no mistake either.

But before we start talking about the Ninja’s sporting capability, let’s be clear about its mission. It is an entry-level sportbike, to be sure, but its upright handlebars and low 30.5-inch seat height make it a user-friendly all-rounder, not unlike Kawasaki’s larger parallel-Twin Ninjas.

As such, this bike is quite suitable for commuting, and we saw upwards of 50 mpg sipped from its comparatively large 4.8-gallon fuel tank, even while testing redline on a regular basis.

Its fairing and windshield offer suitable protection from wind buffeting, and if we can be utterly biased for a moment, we think commuters also looking for a bit of weekend fun might be more satisfied with this 250 over, say, a comparable displacement scooter.

A trip to the aftermarket for luggage options would also be advisable to add to this bike’s utility, or just strapping on a duffel bag to the rear seat could do the trick.

As a Sportbike

The Ninja 250R is sane fun for the street. We won’t pretend to say it’s as adrenaline-inducing as a ZX-6R, but it didn't exactly put us to sleep either.

Acceleration is brisk, and gear changes come fast and crisply. If determined, a rider can twist its tail into the indicated red zone. Whether this is good policy or needed is another issue. As the dyno chart indicates, power progressively drops off past 11,000 rpm, so there’s not much point to flogging it.

When the road gets twisty, cornering is predictable. Its suspension, with 4.7-inches front and 5.1-inches rear travel is reasonably compliant for riders up to 220 lbs or so. Much heavier riders, or those intending to trounce down rough roads, may wish for more adjustability.

Riders accustomed to bikes with four times the power will feel underwhelmed on sweepers because this bike doesn’t go into warp drive when requested like a literbike can, but newer riders, or those just not looking for a ten-tenths experience ought to enjoy the ride. On tighter roads, the Ninja 250R leaves little to be desired. Assuming the rider has the skills, its lighter weight, quick and neutral steering can give larger and faster bikes a run for their money.

Stock tires for our California bike were IRC RX-01 front and rear specific, although Kawasaki may spec equivalent Bridgestones and Dunlops in other regions. Sized at 110/70-17 front, and 130/70-17 rear, the IRC rubber is plenty adequate for most uses. Aggressive riders may want to experiment with premium sport-compound tires when the originals eventually wear out.

To complete its role as an entry-level sportbike, there’s another benefit potentially available. While wearing race leathers during parking lot cornering practice, we discovered that compared to some larger sportbikes, the Ninja’s low saddle and confident handling makes scuffing knee pucks somewhat easier

Kawasaki Ninja 1000 Review - First Ride

According to Kawasaki, the Ninja was conceived and born alongside the revised Z, which was released last year.

The decision to stagger their model years was made in part to meet a perceived greater demand for the allegedly “naked” Zed, particularly in Europe. Also, because sorting the details involved in bringing a new bike to market takes from limited resources, Kawasaki says the Ninja got bumped to 2011.

Speaking of the Ninja 1000 as a variation on the same motorcycle theme, we could nearly summarize it in one sentence and say that if you’re familiar with the Z1000 and can imagine extra wind protection and a bit more plastic, then you practically know the Ninja already.

But to be fair, this isn’t quite true. The Ninja’s above-the-triple-clamps alloy handlebar differs from the tubular bar on the Z1000. They’re about 45mm higher, 10mm narrower, and the grip angle is slightly different. Also its footpegs are set at a somewhat more relaxed position, and the Ninja’s rider and passenger saddle sections utilize 10mm more urethane padding. This extra cush should augment its long-legged comfort potential that also comes with its 1.1 gallon greater fuel capacity.

And then there’s the aesthetic impression, including slightly mellower intake sound due to a deleted “intake-howl” inducing resonator that comes in the Z1000’s intake tract, and a functional full-coverage fairing with a three-way adjustable windscreen. The combined affect makes it feel like its own bike which is kind of surprising, considering on paper

Suzuki RF600


Suzuki's entry in the hot-selling 600cc sportbike class - the RF600 - is a decidedly average bike, one that it will probably emerge as a salesroom winner. A contradiction? Not really: The RF600 is not the most powerful, fastest, nor the best handling mid dleweight, so the folks at Suzuki must be counting on potential buyers to look past the spec-sheet and judge this motorcycle on its merits. This strategy worked for the press-panned Katana series, one of Suzuki's best-sellers in recent years. Will this ap proach be successful for the RF600? It shouldn't be, at least not this year.

Sure, the RF600 has a lot going for it. The sexy full-coverage bodywork turns many heads in all its arrest-me-red glory - from the Ferrari-like side
panel grates to a tailpiece that incorporates a highly visible brake light and a GP-style underbelly fair ing, the RF600 is drop-dead gorgeous. Indeed, it's one of the best-looking bikes we've ever seen. But the beauty here is only skin-deep.

The motor, canted forward 55 degrees to give incoming charge a more vertical path past the intake valves (it's always easier to "drop" charge into the cylinder than it is to suck it "up"), is an upgraded version of the discontinued GSXR600's mill, certa inly not the strongest motor in its class. This 16-valve powerplant barely managed 80 rear-wheel horsepower on a Dynojet dyno.

No, this bike won't be winning any Supersport trophies this year. And it won't be winning any Friday-night drag races, either: Off-idle carburetion is horrible, with a massive flat-spot that lags all the way to 4000 rpm. Launching the RF600 can be like r iding a tempermental two-stroke - get it above the low-rpm flat spot and it'll take off, come off the line with the revs too low, and you'll bog, stall, and generally look like a wimp. This is a new-for-'95 feature, as the '94 version had no such problems .

All of this is wrapped in a steel perimeter frame which is painted to match the bodywork. A few pounds were gained using steel, but it's an acceptable trade-off for Suzuki: Their GSXR line has a tendancy to wobble under high-speed, high-stress (read: racing) situations, and the RF600 exhibited no such traits when we tested it at Laguna Seca. The perimeter frame also gave the engineers more room behind - and above - the motor than the twin-cradle design of the GSXRs, and they made good use of the space . A huge, 6-liter air box mates to a rack of four 33mm downdraft Mikuni carburetors, which in turn feed the motor through a redesigned inlet system.

nts as they ar e blitzing around Laguna Seca Raceway, where we spent a day evaluating the RF.

The revised-for-1995 rear shock offers adjustable spring-preload and more-effective rebound-damping adjustments - Suzuki's have been plagued in recent years with too-soft damping. Unfortunately, this year, Suzuki overshot the mark, dialing in excessive r ebound into the rear. Even on the lowest of four settings, the rear shock still rebounds too slowly, meaning this is one of the few OEM shocks that will actually get better as time wears and it begins to fade.

Tires are high-quality Dunlop D202s that offer excellent grip and acceptable mileage. Wheels are 17x3.5" up front and 17x4.5" out back, meaning that finding high-quality replacement rubber won't be a problem.

Once at speed, the RF is an easy bike to ride fast. Clutch action is light and positive, and there is good throttle response once clear of the flat spot. A six-speed transmission diverts power to the ground and shifts very smoothly with a short click of the shifter. Gear ratios are closely spaced, but without the too-tall first gear found on most race-replicas. The bike turns into corners easily and neutrally, and stays on line without constant rider input. At a claimed 429 pounds dry, the RF is light en ough to be ridden hard without feeling like you've just gone 10 rounds with big George Foreman, and it hides its relatively long 56.3 inch wheelbase remarkably well.

Out on the open highway, a windscreen provides ample coverage to hide behind, and there is an integrated push-to-open glovebox in the left fairing that's within easy reach. The box is big enough to hold a couple packs of smokes, or a garage-door opener. Thankfully the gas tank, which hold 4.7 gallons of juice, is quite tall, meaning that it's a short dip to lean on and rest aching wrists and arms (which will ache, no matter how jaded a sport-bike enthusiast you are!) while cruising.

There is an amber low-fuel indicator light on the dash-panel that alerts the rider when there is about 80 miles left on tap. Expect to see this light often. On average, we went 34 miles per gallon (mpg) in the city and when sport-touring, and about 42 mp g when droning at constant speeds. The light is simply a reminder, as there is also a fuel petcock with reserve switch.

Overall, though, we weren't impressed with the RF. If you don't mind spending the time and money to replace the handlebars (easily changed since they bolt on above the triple clamps) and dig through the carburetors to replace low-speed pilot jets, the RF 600 could be the perfect bike for you. Indeed, once the kinks are worked out, the silky-smooth engine and striking beauty of this machine could make it a timeless masterpiece. But in stock form, Suzuki's missed the mark with the RF600--its flaws simply ou tnumber the benefits, especially for 6699 dollars.

Kawasaki's ultimate high-speed tourer

Mode-changing mechanisms allow the rider to select the riding position and functionality to suit the conditions for example, it can be a low or high speed touring machine and there's even a full-on sports mode where the adjustable fairing and screen takes on its most aerodynamic profile. Borrowing from many exclusive automobiles which offer varying aerodynamics dependent upon speed, the Kawasaki ZZX-R has speed sensitive fairing components which change position depending on speed too.

Some other firsts on display within the concept machine include cone-shaped, rim-mounted disk brakes which are designed for maximum cooling efficiency, and a centrally-mounted fuel tank which is designed to centralise the mass on what is obviously a very large machine.Ample storage capacity has been designed into the machine, with a capacious storage area in front of the seat. Yet another first is the muffler which is built into the bodywork.

Details on the machine are purposefully vague - no weight, no engine details and no power figures have been released, which indicates Kawasaki was attempting to float the concept rather than indicate a specific machine. Perhaps even more significant than the machine which was shown, were the sketches which accompanied the showing. They clearly illustrate a line of thinking which involves an all-purpose bike with different panelling to be clipped on for different purposes - with the add-ons ranging from expandable panniers through to a roof.

2013 Honda PCX150 Review

Now, with the new and improved Honda PCX150, Team Red has directly addressed this issue, boring out the original 125cc, two-valve, programmed fuel-injected engine to 152.9cc, making it officially eligible to hop on the freeway. Of course, being a Honda, while the 125 engine was getting a facelift, engineers made other improvements as well.

If you didn’t know any better, you’d think this PCX had a 125cc engine. But you’d be wrong.

A number of subtle improvements to the cylinder and rocker arm reduce friction, while the piston itself went on a diet, thanks to CAE (Computer Aided Engineering) analysis. A more efficient radiator allows the use of a smaller, lighter cooling fan, and internal modifications reduce oil agitation losses, allowing oil capacity to come down approximately 25% compared to the 125cc version.

All of these low-friction, higher-efficiency adoptions are a reflection of a global initiative Honda calls ESP, or Enhanced Smart Power. ESP’s aim is to develop environmentally responsible scooter engines without compromising performance. Further proof of this initiative is the 150’s “built-in” cooling system.

The 25-liter underseat storage can easily gobble up a full-face helmet with room to spare.

Whereas other scooters place their radiators near the nose or head of the leg shield, requiring complex hose routing, the PCX150’s radiator is placed directly adjacent of the engine, toward the center of its crank axis. This reduces and simplifies cooling system parts, with an added benefit of centralizing weight. Revised gearing results in more oomph when launching from a stop.

Honda claims this world-model scoot will achieve 102 mpg, but it’s interesting to note, in the interest of keeping costs down, the units coming to this side of the pond won’t be equipped with the Idle Stop feature, which shuts down the engine at a stop to conserve fuel. This technology becoming more prevalent in the car world.

The tamper-resistant ignition system uses a simple lever to cover the ignition. Using the plastic key on the key fob unlocks the cover to reveal the ignition.

Other changes: seat cushions use a different material for firmer support, and a new mounting bracket is available to accept an accessory 35-liter top box in case the 25-liter underseat storage and additional 1.5-liter front storage compartment weren’t enough.

Otherwise, the PCX150 remains largely unchanged from its 125cc predecessor. The Honda V-Matic CVT eliminates the need to shift, while a 31mm conventional fork and single shock, offering 3.5 and 3.1 inches of travel, respectively, handle suspension duties. Even styling cues have gone unchanged, still fresh and attractive with its angular, Euro-inspired lines. Bringing the scoot to a stop is a rear drum and single 220mm front disc mated to a three-piston caliper. Honda’s Combined Braking System links rear to front, but not front to rear.

A single 220mm disc is plenty strong enough to slow the PCX in most situations.

At first glance, it’s easy to mistake the PCX150 for its smaller predecessor. Pick it up off the sidestand or centerstand and this feeling continues even from the saddle, as the user interface has gone unchanged. Thumb the starter and the PCX quietly purrs to life like before. The difference is felt once you twist the throttle, as the extra muscle (relatively speaking) noticeably propels the PCX off the line with just a smidge more urgency than the 125cc model. Performance easily trumps anything in the 125 category, and will likely give fits to bigger competition as well.

And being fuel-injected, there’s no worry about waiting for it to warm up. Simply start it and ride away. There’s plenty of squirt to maintain pace with surrounding traffic, though when it comes time to hop on the freeway and reach merging speed, the urgency in its acceleration quickly drops.

Taller riders may find themselves sitting in the pillion seat to ride the PCX, though the long, sweeping floorboards provide plenty of legroom.

I was able to reach an indicated 70 mph before the little scoot plateaued. It wasn’t having any more. Ride quality is supple and compliant, though suspension damping feels more on the firmer side than I remember from the 125. The 90/90-14 front, 100/90-14 rear tires remain unchanged.

With its weight located low and central, the PCX150 has impressive handling characteristics for a scooter.

Apart from the extra grunt from the engine and perceived firmness in the suspension, it was difficult to notice much of a change between new and old. Mainly because there’s not much of one. My 5-foot, 8-inch frame fits nicely in the 29.9-inch high saddle with convenient support from the backrest. Taller riders may want to remove this backrest for a greater breadth of seating positions. Swooping floorboards allow riders to place their feet directly below them or out in front, cruiser style.

With its mass-centralized engine and fuel tank, the bulk of the PCX150’s claimed 286-pound curb weight is low in the chassis, allowing for quick, neutral handling despite its 27.0-degree rake. With its linked brakes, slowing down was never an issue. The front binder scrubs speed just fine for 90% of applications, though using both brakes makes a noticeable difference during emergency stops.

When viewed from a performance and intended design standpoint, the PCX150 is hard to top. With room for a full-face helmet (and then some) under the seat, responsive yet supportive handling, and a freeway-legal, fuel-injected engine, what more could you ask for? Judging from our past experience, Honda’s claim of 102 mpg is hard to believe, but we’ll have to wait until we can get one for a thorough test to find out. Still, expect impressive mileage numbers.

With enough motivation, you can wheelie nearly anything!

Honda says the mid-displacement scooter category is the second-most popular behind the 50cc category, with 66% of sales going to first-time scooter buyers. Interestingly, 20% of these consumers are brand new to two-wheels and 33% are women. At $3,449, it’s difficult to think of a more capable performer for the price.

Hell, maybe I’ll actually end up buying one this time.
