2023 Yamaha YZ450F Service and Repair Manual

LIT-11626-36-32 is the factory service manual for the 2023 YZ450F, written around the model code YZ450FPME. No other year shares its pages.

The engine chapters give the sequence a technician follows: valve clearance and shim selection, cam timing, cylinder head and piston service against wear limits, clutch work, then case splitting for the crank and transmission. Fuel injection and ignition material lists the factory test values rather than general guidance.

Chassis and electrical

• Fork and rear shock service with oil quantity
• Brake, wheel and bearing procedures
• Steering head and swingarm work
• Torque tables for frame and engine fasteners
• Wiring diagram and troubleshooting charts

Read the code off the frame sticker before ordering. YZ450FPME confirms this is the correct book, and LIT-11626-36-32 is the number worth noting for parts enquiries.
