Specs At A Glance

Good To Know

Q: Can this kit be installed without splitting the cases? A: The crankshaft component requires splitting the cases, so plan for a full teardown during installation. If only a top end refresh is needed, the piston and gasket set can be used independently.

Q: Does this piston require re-plating or boring? A: Because it is a 96.00 mm standard bore piston, it suits a stock, undamaged cylinder rather than a resleeved or overbored one. Measure cylinder wear before ordering to confirm it stays within tolerance.

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