Features

Chassis Management Technology

  • ERGO-FIT®: Proper fit is key for rider comfort and control. However, the ideal fit varies from rider to rider, depending on their physical dimensions and riding style. ERGO-FIT® is an interface system designed to allow riders to find their ideal riding position. Various points of the chassis interface (the handlebar, footpegs and seat, etc.) can be adjusted through a combination of interchangeable parts and parts with adjustable positions. This enables a wide range of riders to find a riding position that offers both comfort and control. Feeling at one with their machine, they will be able to experience how Kawasaki machines are fun and rewarding to ride. *Adjustable parts and their range of adjustability vary by model.

Cross-Country Capability

  • TAKE ON TOUGH TRAILS: The KX™450X motorcycle is built to meet the tough demands of cross-country racing. Cross-country wheels (F21"/R18") are paired with specific Dunlop Geomax AT81 tires developed for GNCC racing. A factory-style skid plate and a convenient side stand both come as standard equipment.

Engine Management Technology

  • KLCM (KAWASAKI LAUNCH CONTROL MODE): Designed to assist riders by optimizing acceleration from a stop, KLCM electronically manages engine output to minimize wheel spin when moving off. With the clutch lever pulled in and the system activated, engine speed is limited to a determined speed while the rider holds the throttle open. Once the rider releases the clutch lever to engage the clutch, engine speed is allowed to increase, but power is regulated to minimize wheel spin and help keep the front wheel on the ground. The system disengages automatically once a predetermined speed has been reached, or when the rider shifts into third gear. Depending on the model, riders can choose from multiple modes, each offering a progressively greater level of intrusion.

Ergo-Fit® Ergonomics

  • GET THE PERFECT FIT: Slim ergonomics stem from a narrow frame and minimalist bodywork. To help facilitate the perfect fit, the KX™450X motorcycle features ERGO-FIT® adjustability. Four handlebar positions and two footpeg positions allow you to tailor the KX450X to your body size, riding style and preference.

Features

  • Easy engine tuning.
  • Finger-follower valve actuation.
  • Slim, ergonomic bodywork.

KX™ Chassis Performance

  • GAIN FULL CONTROL: Light and nimble handling is achieved thanks to the lean, lightweight chassis of the legendary KX™450 motocross bike. A well-balanced aluminum perimeter frame helps keep the overall weight down and allows for slim ergonomics. The high-performance, race-ready suspension has been optimized for cross-country racing, especially on aggressive trails. Large-diameter brakes deliver strong stopping power, offering a high level of control.

KX™ Engine Performance

  • POWER AHEAD: The same championship-proven engine performance found in KX™ motocross bikes is what propels the KX™450X motorcycle. This fuel-injected 449cc 4-stroke engine delivers the type of hard-hitting power and a flat torque curve that encourages quick acceleration. Engine maps are optimized for cross-country racing, delivering the ideal amount of useable power. Electric start makes starting the engine as easy as a push of a button. A coned disc-spring hydraulic clutch offers a direct feel, light lever action, and consistent performance.
