FULL DESCRIPTION
Athena Forged Racing Piston Kit 83mm - 300cc Big Bore
Enhance the performance and reliability of your motorcycle with the Athena Forged Racing Piston Kit. Designed for Athena Big Bore Cylinder kits, this piston is engineered in Italy using a special high-performance aluminum alloy with a high silicon content. This advanced material ensures exceptional durability and performance, meeting or exceeding original equipment (OE) standards.
Athena pistons are produced using cutting-edge CNC machining tools, guaranteeing dimensional tolerances of less than 0.01 mm. The precisely engineered piston profile promotes a regular flow and optimal flame propagation for improved combustion efficiency.
This kit includes the forged piston, piston pin, circlips, and piston rings. The piston rings, manufactured in Japan with wear-resistant coatings like PVD or chromium nitride, are designed to minimize friction with the cylinder, leading to higher performance and extended durability. They are engineered to adapt perfectly to the cylinder liner, even under low tangential load.
