Specs At A Glance

Good To Know

Q: Does this piston kit fit a standard bore cylinder? A: No, this is a .040 oversize piston, so the cylinder must be bored and honed to match the 71.00 mm size. Confirm your current bore before ordering.

Q: Is the piston ready to install as shipped? A: Measure your bore and ring end gap before assembly, since final honing tolerance and break-in affect how the piston seats. Follow the piston maker's clearance guidance for your build.

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