Two versions of the 2025 YZ250F sit under one part number. LIT-11626-38-27 was written for the bike coded YZ250FSL and also covers the YZ250F Monster, which shares its mechanical specification entirely.
Engine chapters
- Valve clearance measurement and shim tables
- Camshaft timing and head service
- Piston, bore and crank wear limits
- Clutch and transmission rebuild in split cases
- Fuel injection and ignition test values
Away from the engine, the book details fork and shock disassembly with the specified oil volume, brake and wheel service, bearing replacement and the frame torque tables. The electrical chapter provides the wiring diagram together with diagnostic sequences.
Confirm YZ250FSL against the frame sticker before ordering. Where a bike has been repainted or fitted with parts from a neighbouring year, that code and LIT-11626-38-27 are the only reliable way to know which book applies.
