PISTON KIT A 76.8MM HONDA CRF 250 16-17, ATHENA S4F07680012A STD BORE, KIT A

Athena Forged Racing Piston Kit A - 76.8mm Bore

Enhance your motorcycle's performance with the Athena Forged Racing Piston Kit A. Engineered for exceptional reliability and power, this piston kit is crafted using advanced reverse extrusion and cutting-edge CNC machining for precise dimensional tolerances. Made from a special high-performance aluminum alloy with a high silicon content, it offers superior resistance and excellent performance, matching or exceeding Original Equipment (OE) standards.

The piston features a perfectly smooth profile for optimized airflow and efficient flame propagation. Some applications include a molybdenum disulfide coating on the piston skirt, applied via screen printing, to significantly reduce friction, further boosting performance and durability.

Each Athena piston is meticulously engineered in Italy and rigorously tested on engine dynamometer benches and on the track to validate its performance under extreme conditions. This piston kit includes the piston, pin, circlips, and piston rings, all of which are replaceable and interchangeable.
