PISTON KIT 69MM HONDA CRF 150 07-10, ATHENA S4F069000030 163.5CC BIG BORE

Athena Forged Racing Piston Kit - 69mm Big Bore

Upgrade your engine's performance with this Athena Forged Racing Piston Kit. Engineered for durability and power, this kit is designed to enhance your motorcycle's capabilities. Athena, a leader in motorcycle spare parts for over 40 years, utilizes advanced manufacturing processes to deliver exceptional quality.

This forged piston is crafted from a special high-performance aluminum alloy with a high silicon content. This ensures reliability comparable to Original Equipment (OE) pistons while offering superior resistance and excellent performance. The precisely machined profile guarantees a smooth flow and optimal flame propagation for efficient combustion.

Some piston skirts feature a molybdenum disulfide coating applied via screen printing. This treatment further reduces friction, contributing to enhanced performance and extended durability.

Athena's commitment to engineering excellence means this piston kit meets or exceeds OE production standards, delivering both performance and reliability. Each piston is 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 components are replaceable and interchangeable for convenient maintenance.
