Developed directly from its motocross brethren, the YZ450FX takes that competition-dominating formula and adds a number of cross-country focused features and unique settings to make the ultimate four-stroke GNCC®/Woods racer.
The compact, powerful YZ450FX engine includes all the same race-developed technologies of the class-defining YZ450F motocrosser, tuned for cross country performance. A host of go-fast innovations include steep valve angles, aggressive cam profiles, high-compression forged piston with low friction rings, high-flow intake and exhaust systems—all thoughtfully packaged to optimize mass centralization.
A handlebar-mounted map switch allows the rider to quickly select between preloaded engine maps—loaded and configured in the Power Tuner App—to account for changing riding conditions.
