Athena 01-10 HM CRE Six 50 2T 47.55mm Bore Cast Piston (For Athena Big Bore Cylinder Kit)

This Athena cast piston is made from a special alloy blend of nickel, silica, and aluminum. This material choice helps it stand up to the demands of a 2-stroke engine, offering reliability similar to original equipment but with added resistance and performance. The piston's skirt features a molybdenum disulfide coating, applied through screen printing, which works to reduce friction. This smoother operation contributes to better performance and longer life for the piston.

The manufacturing process uses advanced CNC machining tools, ensuring very tight dimensional tolerances, down to less than 0.01 mm. This precision means the piston will work smoothly within its cylinder, promoting regular airflow and proper flame propagation for efficient combustion. This piston is specifically designed to be used with an Athena Big Bore Cylinder Kit.
