About this product

Description
Athena's piston kits are engineered to withstand the demanding conditions of high-performance 2-stroke engines. This cast piston, crafted from a special high-performance aluminum alloy with high silicon content, matches the reliability of original equipment pistons. It provides high resistance to both mechanical and thermal stresses. The piston's design and material composition have been validated through extensive testing on engine dynamometer benches under progressive stress loads and on the track under the most extreme conditions.

Ideal for rebuilds or performance upgrades, the Athena piston ensures consistent and reliable power delivery.
