FULL DESCRIPTION
Athena Top End Piston & Gasket Kit
This Athena Top End Piston Kit combines a high-performance forged piston with a compatible top-end gasket set, offering a complete solution for engine maintenance and enhancement. Athena designs, develops, and tests all piston technologies and materials internally, ensuring a perfectly tuned kit for superior performance and maximum reliability.
Key Features:
- Forged Piston: Manufactured using advanced numerical control (CNC) machines from a special high-performance aluminum alloy with a high silicon content. This provides excellent reliability comparable to Original Equipment (OE) pistons, while offering enhanced resistance and superior performance.
- Optimized Profile: The piston features a perfectly smooth profile designed for regular airflow and efficient flame propagation. Some piston skirts are treated with a molybdenum disulfide coating to further reduce friction, boosting performance and durability.
- High-Quality Piston Rings: Included piston rings are Made in Japan and feature wear-resistant coatings (PVD or chromium nitride) to minimize friction with the cylinder, increasing performance and extending lifespan. The kit includes 2 segments.
- Reliable Gasket Kit: Athena's extensive experience ensures the reliability of their gasket kits. Developed with deep technical knowledge, constant technological advancement, and strict adherence to manufacturer parameters.
- Precision Gasket Manufacturing: Latest generation lasers are used for cutting, guaranteeing exceptional precision and quality for the gaskets. Surface treatments are employed to address irregularities, and material stress-relieving processes enhance sealing in critical areas.
- Kit Includes: Forged 4-stroke piston and a complete top-end gasket kit.
