Athena 250cc 4-stroke Piston Kit

Upgrade your 250cc 4-stroke engine with the Athena Piston Kit, engineered for superior performance and durability. This kit provides improved resistance and excellent performance.

Description

The Athena Piston Kit is designed for enthusiasts and professionals seeking to maximize their engine's potential. Crafted from a high-performance aluminum alloy with a high silicon content, this piston ensures reliability comparable to OE pistons while offering enhanced strength. The smooth piston profile optimizes gas flow and flame propagation, contributing to a more efficient combustion process. Manufactured using reverse extrusion and CNC machining, this piston delivers unparalleled precision. The piston rings, made in Japan, minimize friction with the cylinder wall, increasing overall performance. The 77.96 mm bore size and 13.5:1 compression ratio are perfectly matched for optimal engine output. Experience the difference with Athena – where quality meets performance.
