Product description

The piston is made of a robust aluminum alloy with a cast structure and has a molybdenum disulfide coating on the piston skirt. This coating reduces frictional resistance between the piston and cylinder liner, contributing to improved mileage and longer service life.

The oversize of +0.50 mm enables use on machined cylinders or to compensate for wear. The compression ratio of 9.1:1 is tailored to the engine characteristics of the Yamaha Grizzly 660 and ensures optimal combustion.

The kit contains all the necessary components for replacing the piston including the appropriate piston rings. The precise manufacturing ensures an exact fit and supports reliable function of the engine.

Scope of application

The piston kit is suitable for use in 4-stroke engines with a displacement of 660 cm³, especially for the Yamaha Grizzly 660. It is used as a spare part for repairs or to optimize performance after cylinder machining.
