The 2025 KX450X is an off-road cross-country competition model that features the same championship-proven technology found on KX race machines and has been purposely tuned for off-road competition. The addition of a 21”/18” wheel combination allows the power of the KX450X to be transferred directly to the ground and the Dunlop AT81 tires make sure the bike can handle the obstacles found in cross-country riding. A high-performance 49mm inverted coil-spring fork and New Uni-Trak rear suspension are inherited from its KX450 brethren, with the spring rates and damping settings optimized for the cross-country environment. The KX450X also comes with a convenient side stand for when at a stop.
