Part number LIT-11626-37-33 identifies the factory service manual for the 2024 YZ250X. Yamaha wrote it around the model code YZ250XR and did not extend it to other years.
The engine material is arranged as a technician would work: top end first, with piston and bore limits, then the power valve, the clutch, and finally the crankcase and transmission. Carburetor settings and ignition test values come from the factory rather than from tuning folklore, which makes them the right starting point after a rebuild.
Chassis chapters handle fork and shock service with oil quantities and assembly order, brake and wheel procedures, bearing replacement, and the torque tables for frame, swingarm and engine mounts. Wiring diagrams and diagnostic charts are included.
Confirm YZ250XR on the frame sticker before ordering. Quoted together with LIT-11626-37-33, that code leaves no ambiguity about which machine this book fits.
