ProX pistons are precision-finished using the latest state-of-the-art CNC machinery. The material used is the same alloy that other leading Japanese engine manufacturers rely on. ProX piston kits are a premium alternative to OEM parts when you need a replacement component for your motorcycle, scooter, moped, ATV or jet ski.

Most ProX pistons feature an OEM-style coating that aids the break-in process.
In addition, ProX has developed a special skirt coating that reduces friction throughout the entire service life of the piston. This black coating is designed specifically to boost performance.

Nikasil-coated cylinders cannot be bored. Pistons are available in 0.01 mm increments (sizes A, B, C). The diameter of this piston is 77.96 mm (standard cylinder bore 78.00 mm).

In addition to the piston, the retail package includes the piston rings, piston pin and circlips.
