Good To Know

Q: Does this piston require boring the cylinder? A: No, it is a standard 81 mm piston meant for cylinders still at original bore. Cylinders with damage or wear typically need machining first.

Q: Should I replace other top-end parts at the same time? A: Rings, wrist pin, bearing, and gaskets are commonly replaced alongside the piston. Confirm your exact model year 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.
