Yamaha Cross Country Bike – WR450F

Description

THE BIKE FOR ALL REASONS

Featuring a new more powerful, user‑friendly engine and an updated frame, this off‑road bike offers enhanced performance for aggressive enduro riding.

 

  • 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 new combustion chamber geometry with steeper valve angles, more aggressive cam profiles, a higher compression piston with low friction rings, longer connection rod, larger exhaust head pipe connector, a high flow air filter, more efficient breather system and 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.
  • Advanced Frame
    Yamaha’s aluminum frame features all-new flex characteristics that give riders the ultimate combination of precise cornering performance, traction and bump stability. By tuning the rigidity balance of the chassis with changes to the lateral beams and engine cradle tube thickness as well as engine mounts, top triple clamp and front axle, the 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.
