Specs At A Glance

Good To Know

Q: Will this piston kit work with a stock cylinder? A: Yes, the 81mm standard bore is sized for a standard cylinder that has not been oversized, but always measure before installation.

Q: Are the piston rings pre-gapped? A: Rings are supplied as standard and may need to be gapped according to your specific cylinder clearance.

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