Featuring a "reversed" rear slanted engine design for mass centralization, minimal bodywork and a proven KYB "SSS" suspension system, the YZ450F offers class-leading power in a 250 sized chassis. For 2016 the engine has been revised, we have added launch control for faster starts and added a larger front disc into the mix. The 2016 YZ450F balances the 3 essential elements of an ultimate motocrosser: easy cornering, lightweight and compactness and a deep, useable powerband.
