Specs At A Glance

Good To Know

Q: Does this piston fit a cylinder that has been bored oversize? A: No, this is a standard 66.00 mm piston and is meant for a stock, unmodified bore. If your cylinder has been bored out, you need the matching oversize piston instead.

Q: Do I need to replace the wrist pin bearing at the same time? A: It is good practice to inspect the wrist pin bearing and small end during a rebuild and replace it if worn. A fresh bearing helps protect your new piston and rings.

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