Athena 21-23 Gas Gas MC 50 39.46mm Bore 2T Cast Piston

Athena has been making motorcycle spare parts for over 40 years, and they're known for their reliable components. This cast piston is designed for your 2021-2023 Gas Gas MC 50, featuring a 39.46mm bore. It's built using special high-performance alloys, including nickel, silica, and aluminum, which are chosen to match the reliability of the original equipment piston while offering improved resistance and performance.

These pistons are made with advanced CNC machining tools, ensuring very tight dimensional tolerances. The smooth profile helps with regular fuel flow and proper flame propagation. For some pistons, a molybdenum disulfide coating is applied to the skirt to further reduce friction, which can enhance both performance and how long the piston lasts.
