FULL DESCRIPTION
Athena Forged Piston Kit B - 76.8mm Bore
Upgrade your engine's performance and reliability with the Athena Forged Piston Kit B. Engineered in Italy by Athena's renowned R&D department, this piston is crafted from a special high-performance aluminum alloy with a high silicon content. This advanced material ensures the same reliability as original equipment (OE) pistons while offering superior resistance and enhanced performance.
Utilizing cutting-edge CNC machining, Athena achieves dimensional tolerances of less than 0.01 mm, guaranteeing precision and a perfect fit. The piston's perfectly smooth profile promotes regular airflow and optimal flame propagation for improved combustion efficiency.
Some piston skirts feature a molybdenum disulfide coating applied through screen printing. This treatment further reduces friction, leading to increased performance and extended durability. Each piston kit includes the piston, pin, circlips, and piston rings, all of which are replaceable and interchangeable.
The included piston rings are produced in Japan with wear-resistant coatings (PVD or chromium nitride) to maximize durability and performance. These rings are designed to adapt perfectly to the cylinder liner even under low tangential load, minimizing friction and maximizing power output.
Athena rigorously tests its pistons on engine dynamometer benches under progressive stress loads and on the track in extreme conditions to validate their performance and reliability.
