Athena 05-10 Kymco HR 300 4T Forged Racing Piston Bore 72.65mm for Athena Cylinder and OE

Forged from a special aluminum alloy with nickel and silica, this Athena piston is built for serious performance. It's made using advanced CNC machining to hold tolerances tighter than 0.01 mm, ensuring a precise fit and reliable operation. This piston is designed to work with both Athena cylinders and your Kymco HR 300 4T's original equipment cylinder, giving you options when you're rebuilding your engine.

Athena has been making motorcycle parts for over 40 years, and this piston reflects that experience. The high-performance alloy provides greater resistance and excellent performance compared to a standard piston, while the smooth profile helps with regular fuel flow and proper flame propagation. You get the reliability you expect from OE parts, but with an added edge for when you push your machine.

This piston is a direct replacement for 2005-2010 Kymco HR 300 4T models. Please note that this part is not CARB approved and cannot be shipped to California.
