2026 Yamaha YZ450F 70TH ANNIVERSARY EDITION Service and Repair Manual

Anyone servicing the 2026 YZ450F 70th Anniversary Edition needs LIT-11626-39-20. Yamaha wrote that volume for this bike, model code YZ450FTSE, and for the standard 2026 YZ450F, because nothing in the commemorative treatment changes the work.

Engine coverage

• Valve clearance measurement and shim tables
• Camshaft timing and cylinder head service
• Piston, bore and crankshaft wear limits
• Clutch and transmission rebuild
• Fuel injection and ignition test values

The chassis chapters document fork and shock disassembly with the specified oil quantity, brake and wheel service, bearing replacement, and the torque figures for frame and engine fasteners. Wiring diagrams and troubleshooting sequences complete the book.

Confirm the code YZ450FTSE on the frame sticker before ordering, then quote LIT-11626-39-20 if you are cross-checking against a parts catalogue.
