Specs At A Glance

Good To Know

Q: What does .060 oversize mean? A: It means the piston is 81.50 mm, larger than the stock bore, so the cylinder must be bored and honed to match before installation. A: Always check piston-to-cylinder clearance with the Wiseco specification for this part.

Q: Can I install this piston without machining? A: No, an overbore piston requires a matching bored cylinder. Installing it in a stock cylinder will cause poor sealing and possible seizure.

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