Specs At A Glance

Good To Know

Q: Do I need to bore my cylinder to install this piston? A: No, this is a standard 81.00 mm piston kit intended for cylinders that are still within original bore spec. If your cylinder is scored or out of round, it will need machining and an oversize piston instead.

Q: Is this kit enough to rebuild my whole top end? A: This kit supplies one piston assembly with rings, wrist pin, and circlips. If you are rebuilding multiple cylinders, order the number of kits that match your engine's cylinder count.

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