About this product
Upgrade your 4-stroke off-road motorcycle with the Athena Piston Kit, engineered for superior performance and lasting durability. This kit provides enhanced reliability and power output compared to OEM pistons, ensuring your engine runs at its peak.
Description
The Athena Piston Kit is designed for 250cc 4-stroke engines and manufactured using a high-performance aluminum alloy with a high silicon content. This ensures exceptional resistance to wear and tear while maintaining the same reliability as original equipment (OE) pistons. The piston's smooth profile optimizes flow and flame propagation for increased efficiency. Precision-crafted through reverse extrusion and CNC machining, this piston guarantees optimal fit and performance. The included piston rings, made in Japan, minimize friction with the cylinder wall, further enhancing performance. The piston rings feature advanced wear-resistant coatings, such as PVD or chromium nitride, providing increased retention and exceptional durability. This kit features a 77.97 mm bore size and a 13.5:1 compression ratio. Upgrade your engine with the Athena piston kit for improved power and dependability.
