PISTON KIT 68MM YAMAHA YFZ 350 BANSHEE 87-06, ATHENA S4C06800001B 392CC BIG BORE

Athena 68mm Piston Kit for Big Bore Cylinders

Upgrade your engine's performance with this high-quality Athena 68mm Cast Piston Kit. Engineered in Italy, this piston is designed for Athena Big Bore cylinder kits, offering a direct replacement for your original component with enhanced capabilities.

Crafted from a special high-performance aluminum alloy with a high silicon content, Athena pistons provide the reliability of original equipment manufacturer (OEM) parts while delivering superior resistance and excellent performance. The cutting-edge CNC machining ensures dimensional tolerances of less than 0.01 mm, guaranteeing a precise fit and optimal function.

This piston features a domed head type and a smooth profile for regular flow and perfect flame propagation. Some piston skirts may also include a molybdenum disulfide coating, applied via screen printing, to further reduce friction, boosting performance and durability. The included piston rings, produced in Japan with wear-resistant coatings like PVD or chromium nitride, are designed for reduced friction against the cylinder, leading to higher performance and extended durability.

This comprehensive kit includes the piston, pin, circlips, and piston rings, all of which are replaceable and interchangeable. Athena rigorously tests its pistons on engine dynamometer benches and on the track to validate their performance, even under extreme conditions.
