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.

NEW FOR 2021

All-New Cylinder Head
The WR450F's already potent engine was treated to a host of go-fast refinements, including 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—all while fitting under a smaller and lighter magnesium valve cover.

Revised Bilateral Beam Frame
The WR450F 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 2021 WR450F takes rider confidence to new levels.

Updated Suspension Tuning
The 2021 WR450F features revised front and rear damping tuned in concert with the updated chassis to improve cornering performance, traction, and bump absorption. With smoother chassis movement, the rider is able to make the most of the engine's exceptional power with greater confidence.

New Braking Systems
A new, more rigid front caliper with new pads and disc boost brake feel and controllability. The front brake rotor dissipates heat more efficiently, for more consistent performance under racing conditions.

Multi-Function Enduro Meter
The newly designed compact meter has a higher contrast liquid crystal display with a fuel consumption indicator. The meter features two modes: Standard and Race. Standard mode displayes the speedometer, two trips meters and clock functions while Race mode features average speed, timer and trip functionality as well as low fuel and engine warning lights.
