LIT-11626-38-16 covers the 2025 YZ450F Monster, whose model code is YZ450FSME, and it is the same book Yamaha published for the standard 2025 YZ450F.

What the engine sections provide is specific and measurable: valve clearances and the shim tables, camshaft timing, cylinder head and piston limits, clutch service, then the full bottom end with case-splitting instructions and torque figures throughout. Fuel injection and ignition chapters list the test readings for chasing a fault.

On the chassis side, fork and rear shock service is set out with the specified oil volume and assembly order, followed by brake and wheel work, bearing replacement and the frame fastener tables. The wiring diagram and its troubleshooting charts round the volume out.

Confirm YZ450FSME against the frame sticker before ordering, and keep LIT-11626-38-16 noted for parts enquiries.
