2025 Yamaha WR250F Service and Repair Manual

The 2025 WR250F is coded WR250FS1 and its factory service publication is LIT-11626-38-53, covering the 2025 model year.

Working on a recent competition four-stroke without the factory figures is guesswork, so this is the reference to have on the bench. It gives valve clearance specifications and the shim procedure, piston and cylinder service limits, fastener torques throughout the engine and chassis, suspension and brake overhaul, fuel injection diagnosis, and the full wiring diagrams. The maintenance schedule is stated in the intervals Yamaha wrote, which matters for a bike still early in its life.

Before ordering, check that the code on your frame plate reads WR250FS1.

The specification pages also set out the recommended lubricants, capacities and adjustment ranges, which are the details most often lost when a bike changes hands. Having them stated plainly avoids a good deal of second-hand advice.
