FULL DESCRIPTION
Athena Top End Piston and Gasket Kit
Enhance your motorcycle's engine performance and reliability with the Athena Top End Piston and Gasket Kit. This comprehensive kit combines a high-performance forged piston with a complete top-end gasket set, designed to work in perfect synergy for optimal results. Athena meticulously researches, develops, and tests all piston technologies and materials in-house, ensuring compatible gasket engineering for a perfectly tuned combination.
Key Features:
- Forged Piston: Manufactured using advanced reverse extrusion and state-of-the-art CNC machinery, this forged piston is crafted from a special high-performance aluminum alloy with a high silicon content. This ensures OE-level reliability while offering increased durability and superior performance.
- Optimized Piston Profile: The precisely smoothed piston profile promotes regular airflow and perfect flame propagation within the combustion chamber.
- Friction Reduction: Certain piston skirts are treated with a molybdenum disulfide coating applied via screen printing, further minimizing friction to boost both performance and longevity.
- High-Quality Piston Rings: The included piston rings, manufactured in Japan, feature wear-resistant coatings (PVD or chromium nitride). These advanced coatings reduce friction with the cylinder, leading to higher performance and extended durability.
- Reliable Gasket Set: Drawing on over 40 years of industry experience, Athena gaskets are renowned for their dependability. Developed by an internal team of engineers and designers, and produced to strict manufacturer parameters, these gaskets ensure excellent sealing.
