PISTON KIT A 58MM KAWASAKI KX 125 03-07, ATHENA S4C05800002A 144CC BIG BORE, KIT A

Athena Piston Kit A 58mm for Big Bore Cylinder Kit

This Athena Piston Kit is designed for big bore cylinder applications, offering enhanced performance and durability for your motorcycle. Crafted with precision and advanced engineering, this kit is engineered to meet the demands of high-performance riding.

Athena pistons are manufactured using a specialized high-silicon aluminum alloy and cutting-edge CNC machining to achieve incredibly tight dimensional tolerances. This ensures exceptional reliability, comparable to Original Equipment (OE) pistons, while providing superior resistance and improved performance. The smooth piston profile promotes efficient fuel flow and optimal flame propagation.

Some pistons feature a molybdenum disulfide coating applied via screen printing to the skirt. This treatment further reduces friction, contributing to enhanced performance and extended durability.

Each Athena piston is meticulously engineered in Italy and rigorously tested on engine dynamometers and on track to validate performance under extreme conditions.

This piston kit includes the piston, pin, circlips, and piston rings. All components are designed for interchangeability.
