Athena Forged Piston Ø 81,96mm for Athena Big Bore Cylinder

This piston for Athena Big Bore Cylinders is equipped with piston rings that guarantee less friction with the Cylinder and therefore a higher performance.

Athena takes care of the development of the pistons down to the smallest detail: the rings are produced in Japan with wear-resistant coatings (PVD or chromium nitride) to increase the retain and the durability. The rings perfectly adapt to the Cylinder liner even at low tangential load.

This piston kit contains the piston, the pin, the circlips, and the piston rings. All components are replaceable and interchangeable in case of need.
