The Kawasaki KX100 is squarely-aimed at that gap between the mini ranks and the pro classes. Featuring a larger frame, the KX100 gives adolescent racers an appropriately-sized machine, so they can focus on riding technique instead of on controlling excessive of power.
The KX100 has larger wheels and tires and more engine displacement than the KX85, and it’s powered by a 99cc liquid-cooled, two-stroke engine that breathes through a 28mm carburetor with a carbon-fiber intake reed valve to aid throttle response, coupled to a smooth-shifting six-speed transmission.
The engine is bolted into a high-tensile steel perimeter frame that has a specially designed gas tank to lower the fuel load, which lowers the center of gravity for improved handling. Adjustable long-travel suspension at both ends helps to smooth even the roughest motocross courses. The 36mm inverted cartridge fork has compression damping adjustment capability and the UNI-TRAK® rear suspension system comes equipped with a shock that is fully adjustable for spring preload, compression and rebound damping. In the braking department, both front and rear discs are mounted with shoulder bolts for easier maintenance.
The KX100 also features aggressive Kawasaki Lime Green and Black graphics with a two-tone seat, just like larger KX models.
FEATURES
Liquid-cooled Engine - Right-hand engine cover provides a separate clutch cover for quick servicing without removing the water pump - Assures greater reliability - Bridges between intake and exhaust ports are machined finish for increased durability - Magneto with lower inertial moment improves low-rpm response - Rotor comes with rare-earth magnets – the unitized piece is small, light and durable - Connecting rod big-end bearing has more rigid cage for improved durability - Intake port shape and cylinder skirt allow cooling air into the crankcase chamber - Primary gear is secured using a lock-nut to help reduce mechanical noise - Metafoam gaskets for the generator and water pump covers improve sealing Kawasaki Integrated Power Valve System (KIPS®) - KIPS system varies exhaust port height for increased horsepower and torque - Produces a broad powerband with more low-end torque while retaining excellent top-end power - Breather added to KIPS cover to improve high-rpm and overrun performance 28mm Keihin Carburetor - Crescent slide carburetor puts the needle closer to the intake ports for excellent throttle response - Adjustable for various conditions Clutch - Clutch hub rides on needle bearings for smooth action - Large clutch plates are 119mm in diameter for durability and control - Clutch-release lever ratio provides light clutch lever action - Thick clutch basket housing improves durability
