FULL DESCRIPTION
Athena Forged Big Bore Piston Kit
Enhance the performance and reliability of your motorcycle with this Athena Forged Big Bore Piston Kit. Engineered in Italy by Athena's R&D department, this piston kit is designed for superior strength and durability.
Crafted from a special high-performance aluminum alloy with a high silicon content, Athena pistons offer excellent resistance and performance, rivaling OE specifications. The kit features advanced technical solutions and adheres to the highest quality standards.
The piston's smooth profile ensures optimal airflow and perfect flame propagation. Some piston skirts are treated with a molybdenum disulfide coating, applied by screen printing, to further reduce friction, boosting performance and extending lifespan.
This piston kit is specifically designed for Athena Big Bore cylinder kits and includes high-quality piston rings produced in Japan with wear-resistant coatings (PVD or chromium nitride) for increased durability and longevity. The rings perfectly conform to the cylinder liner, even under low tangential load, ensuring reduced friction and higher performance.
