Description

Athena Forged Racing Piston Kit Ø 71.96 mm is designed for the Athena Big Bore Cylinder, offering high-performance durability and precision engineering. Manufactured using advanced CNC machining for tight tolerances of less than 0.01 mm, this piston is made from a high-performance aluminum alloy with a high silicon content for enhanced strength and reliability. The piston’s smooth profile promotes optimal flow and flame propagation, while certain models feature a molybdenum disulfide coating on the skirt to reduce friction. Engineered and tested in Italy under extreme conditions, this piston kit ensures excellent performance and longevity.
