The same championship-proven engine performance found in KX™ motocross bikes is what propels the all-new 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.

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.

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.

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.
