Two years, one book. Check the code on your frame against YFZ450SET so you are reading the right column, since even across a short run there are values that differ.

Inside the book

• Inspection intervals and the adjustments behind them
• Engine and transmission overhaul with clearances and wear limits
• Torque figures and tightening sequences
• Fuel and ignition specifications
• Electrical testing with factory readings
• Steering, suspension, brake and drivetrain repair
• Complete wiring diagrams and troubleshooting tables

This is the reference a dealer technician used, written procedurally and without commentary. For a sport quad that spends its life near its limits, that level of detail is the difference between a rebuild done to specification and one done by feel.
