PISTON KIT 100MM HONDA CRF 450 02-14, ATHENA S4F10000005A 100MM BIG BORE

Athena Forged Racing Piston Kit - Big Bore Upgrade

Elevate your motorcycle's performance with this Athena Forged Racing Piston Kit. Designed for big bore applications, this kit is crafted from a special high-performance aluminum alloy with a high silicon content, ensuring both exceptional reliability and increased resistance compared to OE pistons.

Athena's pistons are manufactured using cutting-edge CNC machining tools, guaranteeing dimensional tolerances of less than 0.01 mm. The advanced design features a perfectly smooth profile for optimal airflow and efficient flame propagation. Some applications may include a molybdenum disulfide coating on the piston skirts, applied via screen printing, to further reduce friction and enhance performance and durability.

Engineered in Italy by Athena's R&D department, each piston undergoes rigorous testing on engine dynamometer benches and on the track to validate its performance under extreme conditions. This high-compression piston is specifically designed for Athena Big Bore cylinder kits and features piston rings that minimize friction with the cylinder wall, leading to higher performance. The piston rings themselves are produced in Japan with wear-resistant coatings, such as PVD or chromium nitride, for increased lifespan and durability. These rings are designed to perfectly adapt to the cylinder liner even under low tangential load.

This comprehensive kit includes the piston, pin, circlips, and piston rings. All components are replaceable and interchangeable.
