Athena's traditional line of high performance racing pistons specifically designed for all off-road bikes, has reached end-of-line. All of the "S4F" pistons have been reduced to clear.

Produced with the latest technologies, to the industries tightest tolerances, they are made using aluminium alloys that have the perfect balance of nickel, copper, and silicon offering exceptional characteristics of lightness and endurance. The result is better engine performance and durability. Available for most off-road 4 stroke bikes.
