Good To Know

Q: Do I need to replace the piston rings as well? A: Yes, this kit includes new piston rings that should always be installed together with the piston to ensure proper sealing and break-in.

Q: Can I use this piston on a standard bore cylinder? A: No, this 0.020 overbore piston requires the cylinder to be honed to 81.5mm. Always measure your cylinder bore before ordering.

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