Good To Know

Q: Does this kit include the rings and pin? A: Yes, this Wiseco piston kit ships with the piston, rings, wrist pin, and circlips for a complete top-end install. Q: Can I fit this piston without boring the cylinder? A: No, a .040 oversize piston requires the cylinder to be bored and honed to the matching 80.00 mm size for proper clearance.

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