Specs At A Glance

Good To Know

Q: Can this piston run on regular pump fuel? A: A 10:1 compression ratio is generally compatible with pump fuel, though the correct octane rating for the engine should still be followed. Q: Is this a direct replacement for the stock piston? A: It is a standard 103mm bore piston sized to the original cylinder, but cylinder condition and clearances should be checked 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.
