Good To Know

Q: What is included in this piston kit? A: The kit includes the piston, piston rings, wrist pin, and circlips — everything needed for a .020 over bore rebuild.

Q: Is this piston compatible with the stock cylinder? A: The cylinder must be bored to 91.5mm to match this piston, so professional machine work is required before installation.

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