Specs At A Glance

Good To Know

Q: Will these pistons work with stock cylinders? A: They are designed for .040 oversize bores, so cylinders must be machined to 65mm to accept them.

Q: Do they require any special assembly steps? A: Proper ring gap and clearance checks are necessary; follow the engine manufacturer's service manual for installation.

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