About this product
Upgrade your 4-stroke off-road motorcycle with the Athena Piston Kit, designed for superior performance and lasting durability. This kit provides enhanced reliability and power, ensuring your engine operates at its peak potential. Experience improved combustion and reduced friction for a smoother, more efficient ride.
Description
The Athena Piston Kit is crafted from a high-performance aluminum alloy with a high silicon content, guaranteeing reliability comparable to original equipment (OE) pistons while offering increased resistance and exceptional performance. The piston's smooth profile ensures consistent flow and optimal flame propagation, maximizing combustion efficiency. Specifically designed for 4-stroke off-road motorcycles, the piston is manufactured using reverse extrusion and precision CNC machining. This meticulous process ensures tight tolerances and perfect fitment. The included piston rings, made in Japan, minimize friction against the cylinder walls, resulting in higher engine output and improved overall performance. Furthermore, the segments feature wear-resistant coatings (PVD or chromium nitride) to enhance retention and extend durability. This kit is a direct replacement, ensuring straightforward installation and compatibility with your existing setup. With a 13.4:1 compression ratio and 76.96 mm bore size, this Athena 250cc Piston Kit delivers the performance and reliability you demand.
