Yamaha's service manual for the 2025 YFZ450R is part number LIT-11616-27-31, and the machine carries model code YFZ45YSXSL.

The coverage is unusually wide for a current model. This one volume documents the YFZ450R from 2014 through 2026, and it takes in the YFZ450R SE and YFZ450R Special Edition as well, so the variants are handled alongside the standard machine with differences noted where they exist. If you own more than one year of this platform, that is one reference rather than several.

Chapters cover periodic inspection and adjustment, engine and transmission service with clearances, wear limits and tightening sequences, fuel injection and ignition specifications, electrical testing with the readings Yamaha expects, and chassis repair across steering, suspension, wheels, brakes and drive. Wiring diagrams and troubleshooting tables are included.

Confirm YFZ45YSXSL on the frame, then use LIT-11616-27-31 as the primary source for every figure.
