Specs At A Glance

Good To Know

Q: Will this piston drop into a stock bore? A: No, this is a .080 oversize piston, so the cylinder must be bored and honed to match 56.00 mm before installation.

Q: Does the kit include rings and a pin? A: Wiseco piston kits of this type typically ship as a complete assembly, but confirm the exact contents listed by the seller 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.
