The championship-proven technology of KX race machines has now been tuned for off-road competition. Purposefully designed to take on tough off-road conditions, the all-new KX250X motorcycle delivers the edge to ride ahead. No matter how technical the terrain, lead with confidence on the KX250X.

Experience Legendary Power

The KX™250X motorcycle features the same podium-ready engine of the legendary KX™250 motocross bike. This fuel-injected 249cc 4-stroke engine delivers high-revving performance to power past the competition. 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.

Compete With Confidence

Light and nimble handling comes by way of a lean, lightweight chassis, the same one featured on the KX™250 motocross bike. Overall weight is kept low thanks to a well-balanced aluminum perimeter frame, which also allows for slim ergonomics. The high-performance, race-ready suspension has been optimized for cross-country racing, especially on aggressive trails. Large-diameter disc brakes deliver strong stopping power, offering a high level of control.

Take on Tough Trails

The KX™250X motorcycle is built to meet the tough demands of cross-country racing. Cross-country wheels (F21”/R18”) are paired with soft-to-intermediate terrain Dunlop Geomax AT81 tires. A factory-style skid plate and a convenient side stand both come as standard equipment.

Get The Perfect Fit

Slim ergonomics stem from a narrow frame and minimalist bodywork. To help facilitate the perfect fit, the KX™250X motorcycle features ERGO-FIT adjustability. Four handlebar positions and two footpeg positions allow you to tailor the KX250X to your body size, riding style and preference.
