2014 Kawasaki KX100

A New Challenger Helps Riders Prepare for the Big Time!

IRVINE, CA – July 8, 2013 – (Motor Sports Newswire) – The Kawasaki KX™100 represents a natural step in the progression of any budding young motocrosser who has outgrown the 85’s, but could still stand to grow a few more inches, gain a couple more lbs. or simply put in a little more seat time before jumping aboard a powerful, full-sized KX250F. The new KX100 offers the perfect blend of a proportional power increase and a physically larger chassis for a more gradual learning curve en route to the big bikes.

2014_KX100F_LIM_RF_OR.highThe KX100’s liquid-cooled two-stroke engine delivers more power by virtue of its greater displacement. Its 99 championship-bred cubic centimeters deliver hard-hitting power and a broader power curve than the KX85, thanks in part to the proven Kawasaki Integrated Power-valve System (KIPS®) which amplifies the KX100’s low-end torque and creates a more seamless transition to its furious top-end rush. Crisp throttle response is also assured through the KX100’s 28mm Keihin carburetor and carbon-fiber reed valve assembly, while a durable, smooth-shifting six-speed transmission offers the perfect ratios for tackling any obstacle on the track

The KX100’s host of performance- and reliability-improving changes start at the top of its capable engine. A new cylinder head gasket with a 1mm increase in bore surface height is held in place with an additional dowel pin to prevent detonation and increase engine reliability. The KX’s durable, Nikasil-plated cylinder also features a larger exhaust port that is optimally shaped for better flow, improving peak power at wide open throttle. A new piston uses a single piston ring, rather than two rings, to reduce cylinder wall friction for even better engine response.

The power increase warranted changes to maintain the KX100’s bold yet flawless power character. Its 28mm Keihin PWK carburetor receives new jetting specs for optimized fuel atomization and smoother fuel delivery throughout the improved powerband. Further enhancing the KX100’s mid-range and top-end power is a revised Kawasaki Integrated Power-valve System (KIPS®) with new independent valves for each port that replace the previous three-piece valve design, reducing maintenance and further improving reliability.


More durability improvements can be found in the KX’s crankshaft, which is now 83mm, 2mm larger than the previous model, and features a precisely shaped resin block added to the crankshaft to close the gap around the machined area near the crank pin. The resin block reduces the volume of the bottom-end to increase intake transfer to boost power as well as increasing rigidity and durability. More power usually generates more heat, but the KX100’s new radiator increases cooling capacity by nearly 52% to improve engine life and reduce the chance of engine overheating during grueling motos.

The KX100’s six-speed transmission delivers smooth and positive shifting along with extreme durability thanks to its hard chrome-finished shift fork ends, a thick base on the clutch basket housing and an additional bushing on the input shaft.

All of the engine improvements to bolster the KX100’s class-conquering horsepower would be worthless if the suspension couldn’t put that power to the ground, but a new Uni-Trak® linkage equipped KYB reservoir shock, and revised valving in the KYB 36mm inverted fork help ensure that the KX100 can thrive in the roughest motocross terrain. Just like its big brothers, the KX100’s fork now features shim-type valving and firmer damping for faster riders while also offering superior bottoming resistance, but a wide range of adjustability allows it to be tailored for precise damping to fit a variety of riding styles as well as track conditions. Out back, the new shock’s black-anodized aluminum body is 150 grams lighter, while a new clicker-type adjuster makes fine-tuning the rear suspension damping quick and easy.


New petal-type brakes improve the KX100’s stopping power, too. The 220mm front and 184mm rear rotors deliver strong, efficient braking performance while the shape of the petals helps clean the brake pads—a real plus in muddy conditions. The front brake hose is now routed behind the axle for better protection, and it gets new hose guides that are just like the guides on the big KX models. The KX100 also wears new Dunlop® Geomax MX51 intermediate tires that help provide optimal grip over varying terrain and riding conditions.

The KX100’s high-tensile steel perimeter frame is reinforced in key areas to maintain Kawasaki’s legendary handling traits and works in perfect harmony with the more potent engine, improved suspension and more powerful brakes, but significant ergonomics and styling changes greatly improve the KX’s overall look and feel. Its 34.3” tall seat height fits a wide variety of growing inseams. More adjustability than ever before is available on the KX100, thanks to a new wider and taller handlebar, three-position handlebar risers and two-position handlebar clamps that offer a total of six different handlebar positions to custom tailor rider ergonomics for a comfortable fit.

The KX100, also looks as fast as it runs, thanks to bold new factory racer styling that is virtually identical to the big KX models. A new fuel tank with a 20mm lower fuel cap, slim radiator covers and side panels blend harmoniously with a new, flatter two-tone seat that features a seamless cover and gripper material to improve cockpit room and increase rider comfort. A new angular front fender, number plate and white rear fender not only match the big KXs, but the front fender also help to reduce mud accumulation, while new wrap-around fork guards protect the inner fork tubes and seals. Last but not least, a new brushed finish on the aluminum swingarm helps keep the KX100 looking fresher longer.

2014_KX100F_LIM_LS_OR.highCompleting its factory-racer styling, the KX100 is finished off in Kawasaki’s signature lime green with eye-catching detail appointments such as blue alumite coatings on the adjusters and black alumite coating on the rims, just like Villopoto’s factory KX450F.
