Specs At A Glance

Good To Know

Q: Does this piston kit include rings and clips? A: Yes, a complete piston kit commonly ships with the piston, ring set, wrist pin, and circlips for a full top end rebuild.

Q: Do I need to check bore clearance before installing? A: Always measure the cylinder bore and piston clearance against the manufacturer specification, since a worn or out of round cylinder can affect ring seal and piston life.

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