KAWASAKI'S FORMIDABLE FLAGSHIP, THE 2008 NINJA® ZX-14 FINE-TUNED FOR EXTRA FIREPOWER
Every champion knows sustained dominance is only possible with constant improvement. Such is the case with Kawasaki's Ninja® ZX-14. Since its debut in March of 2006, this motorcycle has ruled the open class sportbike roost with nearly non-stop magazine comparison victories. Even though the 1352cc Ninja ZX-14 won lavish praise for its massive torque, effortless power, agile handling and comfortable ergonomics, Kawasaki engineers were not willing to leave the door open to potential challengers.
The 2008 ZX-14 retains all the great features that made it a legend, plus more bottom, mid and top-end power. Changes to the engine and exhaust system allow it to comply with strict Euro-III emissions and tightening noise regulations. To meet noise standards, the engineers focused on reducing internal mechanical noise instead of muzzling the exhaust system. The result wasn't a power loss, but an overall improvement of the engine character and an actual increase in the ZX-14's legendary peak power! Yes, you read that correctly. Emissions and noise levels are lower, peak power is higher, the mid-range hit is stronger and smoother and low-end torque has been increased. A win-win solution for all, in our books.
To achieve those stringent emission levels, a third honeycomb catalyzer was added in the collector, joining the two honeycomb catalyzers already in each silencer. The secondary air ports in the cylinder head and its cover were made approximately 20 percent larger to permit an easier air flow into the exhaust system. A new Air Switching Valve (ASV) caps off the low emission updates and can handle approximately five percent more flow than the last year's version.
Conquering the challenging Euro-III regulations is admirable, but Kawasaki took it to the next level on the ZX-14 with changes to its 1352cc engine which improve the power characteristics while meeting noise regulations. The injection system was first to receive attention in an effort to boost peak power, give a more linear mid-range and stronger low end torque with the same user-friendly personality. The fine-atomizing fuel injectors had their lateral spray angle increased from 15 to 20 degrees to disperse the atomized fuel over a wider area and the intake porting was revised to provide optimum flow characteristics. Outside of the engine, the exhaust silencers feature refinements to the capacity of the first and third chambers and the lengths of the pipes projecting from the baffle plates have been adjusted. Next the entrances to the connecting tubes (joining header pipes 1-4 and 2-3) were enlarged approximately 75 percent to compensate for the new collector shape, which was altered to allow the inclusion of a third honeycomb catalyzer. These changes were a major component of the enhanced the torque characteristics, especially in the low rpm range.
Reducing internal mechanical noise allowed for the engineers to employ comparatively little exhaust modification to meet noise mandates and consequently the exhaust system could remain free flowing for greater power. Lower mechanical noise was attained by revising the piston profiles and adding a urethane insulation sheet to the inside of the magnesium chain cover.
The engine and exhaust system weren't the only areas updated for 2008. The ZX-14's chassis design is every bit the equal of its power plant. Using an advanced version of Kawasaki's unique aluminum monocoque design, its frame is lightweight and very strong. Switching to die instead of gravity casting for the cast aluminum sections of the main frame resulted in lighter parts, allowing the Kawasaki engineers to shave weight on the already slim and compact frame.
Featuring a relaxed sport riding position, the ZX-14 is compact without being cramped, with its bars positioned within easy reach. The narrow engine, monocoque frame, and fuel tank provide a slim rider interface. Footpegs are low-set to give ample legroom and the low seat height and narrow seat front make it easy to plant both feet on the ground when stopped. Comfort levels are high enough that riders might think they're on a dedicated sport tourer, but one twist of the ZX-14's throttle is all it takes to remind anyone this is the world's quickest and most powerful production motorcycle.
Uninterrupted fairing lines give the ZX-14 a smooth, flowing appearance from front to rear due in part to the monocoque frame that goes over the engine and doesn't protrude through the cowling. Quadruple projector beam headlights adorn the ZX-14's front, with low beams in the two center lenses and the outer lenses containing the high beams and position lamps. The turn signals are cleanly integrated into the fairing and rear cowl with a unique "V" design LED tail lamp capping off the sleek aerodynamics of the ZX-14 that reinforces Kawasaki's aircraft heritage.
This blending of form, power, and handling characteristics yields a motorcycle with appeal that extends far outside of its high performance audience. The Ninja ZX-14 lives up to its Ninja heritage, by surpassing the competition.

KAWASAKI'S 2008 NINJA® ZX-10R SUPERBIKE IS POISED FOR COMPETITION
Factory Superbike Talent in a Street Savvy Performer
For the 2008 NINJA® ZX-10R, Kawasaki engineers aimed for an ideal superbike with engine and chassis performance capable of satisfying professional racers, combined with top-notch streetbike qualities for mainstream riders. It's a delicate balance, but these aren't your average engineers. They've been directly involved in the development of every 600 and 1000cc supersport machine since the 2003 Ninja ZX-6R, plus Kawasaki's factory Superbike racing efforts, so they have the know-how to deliver the goods.
The result is an exceptionally communicative machine that provides the clean two-way rider/machine dialog demanded by professional racers. Placing the ZX-10R in the racing crucible and applying lessons from that unforgiving environment resulted in an ideal balance to satisfy the most demanding of riders. Japanese Superbike racer Akira Yanagawa was the man pushing the engine and frame components to the limits of their performance in actual competition. Parts that met with Yanagawa's approval were then tried on the production test bike, tweaked, retested on the racer and adjusted again. This process was repeated throughout the development cycle for the all-new 2008 Ninja ZX-10R.
At the heart of this capable package is a new engine tuned for even greater high-rpm performance, without sacrificing the stellar mid-range performance of its predecessor. Refinements include installing secondary fuel injectors, changing to oval throttle bodies and reshaping the intake ports. Intake flow was further enhanced with reshaped ram air ducts and a larger airbox that feeds into the new oval shaped velocity stacks. Exhaust efficiency was boosted with a new system that not only flows better but generates less noise and emissions. And to suit the enhanced power delivery, the transmission features new gear ratios for 1st, 4th and 5th gears along with an extra tooth on the rear sprocket. These changes make it essentially a race-ready engine with performance similar to Kawasaki's factory Superbikes.
Professional riders know it's useless to have the most power if you can't get it to the ground. The 2008 Ninja ZX-10R features a new ignition system that assists with torque management by monitoring throttle opening, gear position and rate of RPM change, then retarding ignition timing to reduce torque when sudden unwanted RPM spikes are detected. This system doesn't interfere with normal operation and still allows the engine to rev freely under typical riding conditions.
A superb engine deserves a superb chassis, and this is where the new ZX-10R really shines. To achieve the best-possible handling, Kawasaki used the lessons learned at the track to build a list of refinements including: changing the length of the steering tube and moving it 10mm forward, alleviating stress concentrations through subtle changes to the frame stampings (switching concave parts to convex pieces), increasing the wall thickness around the relocated swingarm pivot, adding ribbing on the interior of the pivot plate, and mounting a narrower, two-piece sub-frame to the main frame's upper cross member.
With a fully-adjustable 43mm inverted fork and a new swingarm that uses pressed instead of cast beams, the ZX-10R's track orientated suspension endows the chassis with better feedback. Refinements include adding a Diamond Like Carbon (DLC) coating to the fork tubes for less stiction and enhanced feedback, relocating the springs to the bottom of the fork for reduced oil frothing, and new settings that are better-suited for racetrack use. Rear suspension changes include dual (low and high-speed) compression damping on the fully-adjustable rear shock for better fine-tuning, a new mounting spot for the Uni-Trak® linkage and a re-shaped swingarm with a top-mounted brace.
No part was left untouched on the ZX-10R, even the wheels are new. Produced using a squeeze-casting process instead of the earlier gravity casting method, the new wheels are lighter, stiffer and more precise, to perfectly match the new chassis. The lower unsprung weight of the wheels helps improve suspension action and their reduced rotational inertia provides quicker steering and acceleration.
Braking duties are handled by radial mounted Tokico brake calipers squeezing new 310mm petal discs which are 10mm larger for 2008, and feature reduced thickness from 6 to 5.5mm for better heat dispersion. The rear is a 220mm petal disc squeezed by a single-piston caliper.
The designers didn't rest when it came to styling either. Given great freedom with the 2008 ZX-10R, their efforts are illustrated in the clean design with superb fit and finish. While shaping the rear frame, tank and seat to offer improved ergonomics and increase the rider's contact with the bike, they also refined its aerodynamics from a new front cowling to the sharp, minimalist tail cowl.
The result of these efforts is a slim and compact package with the presence befitting its Ninja name.

THE ULTIMATE LIGHTWEIGHT DUAL PURPOSE MOUNT, THE KAWASAKI KLX250S
A leaner, meaner and greener lightweight dual-sport machine
The fun doesn't have to stop at pavement boundaries when riding Kawasaki's street legal KLX250S. This lightweight dual-purpose motorcycle is equally at home on the pavement or off-road and always ready for your next adventure. Now, thanks to significant updates that saw refinements made everywhere from its improved braking prowess to its aggressively styled bodywork, the KLX250S is more fun than ever.
A compact, liquid-cooled, four-stroke, single-cylinder engine displacing 249cc, the KLX250S features convenient electric-starting. The engine is mounted beneath a lightweight, high-tensile steel perimeter frame to deliver a low center of gravity and enhanced maneuvering on tight trails.
A gear-driven engine balancer means reduced engine vibration for greater comfort and less fatigue on longer rides. The 34mm semi-flat slide Keihin CVK carburetor boosts throttle response and contributes to improved power. It also helps to provide increased fuel economy. The addition of a new evaporative emissions system allows it to meet strict CARB regulations, making the KLX250S eligible for sale in all 50 states.
Further refinements appear in the transmission. Closer ratios between 5th and 6th gear enhance the KLX250S' high-speed off-road capabilities, while a reshaped shift cam offers a more positive shift feel and promotes firmer gear engagement.
The rigors of off-road motorcycling dictate additional protection for the exposed underside of most machines. The KLX250S comes standard with aluminum engine guards to protect its crankcase during off road adventures. Negotiating tight terrain also highlights another off-road reality - heat. The incorporation of dual lightweight, high-capacity Denso radiators and a shallow-footprint cooling fan is an ample solution to potential heat issues.
The rake was increased a degree to 27.5 to boost straight-line stability, which is further enhanced by the rigid square-section frame. Thanks to its short wheelbase, the stability improvements didn't sacrifice any of the 250S' outstanding nimbleness or turning aptitude. At the other end of the chassis, a new lightweight aluminum swingarm employs a highly-rigid D-shaped cross section and features new KX racing-type chain adjusters for precise chain adjustment.
For 2009, the KLX250S received revised damping settings and reduced wheel travel at both ends, plus an all-new rear suspension linkage. These modifications help to increase straight-line stability, give a more planted feel in corners and make it easier for riders to reach the ground. The 43mm inverted cartridge-style front fork and Uni-Trak® rear suspension both come with 16-way adjustable compression damping and offer 10.2-inches and 9.1-inches of travel, respectively.
New wheels feature 0.5mm thicker spokes for increased wheel rigidity and enhanced off-road durability. The KLX250S also offers upgraded stopping power from a twin-piston caliper and a 250mm semi-floating petal disc up front and a larger 240mm petal disc at the rear.
Finishing off this reworked package is a completely new set of aggressively styled bodywork, a re-shaped seat with firmer urethane, and a handlebar with a straighter profile.
The KLX250S offers serious capabilities in a fun, easy-to-ride package, regardless of where the adventure takes it. Riders seeking enduro handling and modern engine performance in a dual-purpose motorcycle designed for effortless street riding will find it at their local Kawasaki dealership.
