FULL DESCRIPTION
Athena Forged Piston Kit for Honda CRF 250 (2014-2015) - 76.76mm Bore
This Athena forged piston kit is engineered for high-performance off-road motorcycles. Manufactured using cutting-edge CNC machining, it ensures precise dimensional tolerances for optimal engine function. The piston is crafted from a special aluminum alloy with a high silicon content, offering the reliability of original equipment (OE) pistons with enhanced durability and performance.
The smooth piston profile promotes regular airflow and perfect flame propagation. Some piston skirts feature a molybdenum disulfide coating, applied via screen printing, to further reduce friction, boosting performance and longevity. Athena's commitment to quality means this piston meets or exceeds OE production standards, validated through rigorous engine dynamometer and track testing.
Included piston rings are designed for reduced friction against the cylinder, contributing to higher performance. These rings are produced in Japan and feature wear-resistant coatings like PVD or chromium nitride for increased durability. The rings are designed to adapt perfectly 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 for convenience.
