- Next-Gen Enduro Racer Based on Flagship YZ450F™
The WR450F™ builds on Yamaha’s exceptional motocross race platform with added features and unique settings designed to optimize the WR® for enduro riding. - Potent Electric Start Engine
A high-compression cylinder head, forged piston, aggressive cam profiles, cylinder geometry and much more work together to give WR450F riders a broad spread of useable thrust with expanded high-rpm power. All available with the convenient push of a button starting that features a compact starter motor system battery. - Advanced Alloy Frame
Yamaha’s bilateral beam aluminum frame is derived straight from the YZ450F to centralize mass and provide an ideal balance between cornering feel and straight-line confidence. - Class-Leading Suspension
Yamaha uses KYB® spring-type forks on the WR450F, with industry leading functionality and easy tuneability for a wide range of conditions. - EPA-Compliant Emissions
Thanks to carefully balanced ECU tuning and the Forestry Service-complaint spark arrestor-type muffler, the WR450F is ready to go where you want, when you want.
