Specs At A Glance

Good To Know

Q: Do I need to measure my cylinder before ordering? A: Yes, confirm your bore size and current piston match the 52.50mm spec, since a worn cylinder may need replating or boring before installation.

Q: Should I replace the rings if I am reusing the piston? A: New rings should be installed any time the top end is opened, and this kit supplies a matched set for correct sealing.

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