Specs At A Glance

Good To Know

Q: Are the rings pre-gapped? A: Rings are not pre-gapped; they must be properly fitted to the rebored cylinder during installation.

Q: Will this fit a Kawasaki KFX80 without reboring? A: This is an oversize piston and requires the cylinder to be rebored to 51mm; it will not fit a standard bore cylinder.

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