PISTON KIT 63MM HONDA CRE/YAMAHA WR 125 08-11, ATHENA S4C06300002A 182CC BIG BORE

Athena 63mm Big Bore Piston Kit for 125cc Off-Road Motorcycles

Enhance the performance and reliability of your off-road motorcycle with this high-quality cast piston kit from Athena. Designed for big bore cylinder applications, this kit is engineered using advanced CNC machining for exceptional precision and durability. The specialized aluminum alloy with a high silicon content ensures superior resistance and performance while maintaining the reliability of original equipment.

The meticulously crafted piston profile promotes smooth airflow and efficient flame propagation for optimized combustion. Certain piston skirts feature a molybdenum disulfide coating applied via screen printing, which further reduces friction, boosting both performance and longevity.

Athena's commitment to quality is evident in every component. These pistons are developed and tested rigorously in Italy, undergoing engine dynamometer and track validation to ensure they perform under the most demanding conditions. This piston kit includes all necessary components for installation:

• Piston
• Piston Pin
• Circlips
• Piston Rings

All parts are designed for interchangeability and can be replaced individually if needed. The included piston rings are produced in Japan with wear-resistant coatings (PVD or chromium nitride) for increased durability and to ensure a perfect seal with the cylinder liner, even under low tangential load, leading to reduced friction and higher performance.
