For over 10 years Athena has worked with the best motocross racing teams in the world to develop pistons.
All piston models are made from aluminum alloys and have a perfect blend of nickel, copper and silicon.
Designed and manufactured with the best technology available.
The careful selection of top quality raw materials, together with the latest mechanical engineering techniques, guarantee the lightness and resistance of the pistons,
