Specs At A Glance

Good To Know

Q: Is this kit compatible with the 2018 Yamaha YZ450F? A: No, this kit is designed specifically for 2014-2017 models; the 2018 and later engines use a different bore size and configuration.

Q: Do I need to replace the cylinder or just the piston? A: If your cylinder is within service limits, you can reuse it; otherwise, a reconditioned or new cylinder is recommended for best results.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
