2022 Yamaha WR450F Service and Repair Manual

For the 2022 WR450F, the factory reference is LIT-11626-35-44 and the machine is identified as WR450FN. Coverage is the 2022 model year.

Structure follows Yamaha's own order, from general specifications and periodic maintenance through the engine, the chassis, the fuel system and the electrics. Tightening torques and service limits sit with the procedures that use them, valve clearance and shimming are set out step by step, and the wiring diagrams are the complete drawings rather than simplified extracts.

Check the code stamped on your frame plate against WR450FN before ordering. A 2023 machine reads differently and takes a different publication.

Capacities, lubricant grades and adjustment ranges are listed in the specification pages. The manual is dealer material rather than a rewrite, so the figures are the factory's own and nothing has been rounded off for readability.
