Description

Athena has been constantly investing in cylinder aftermarket replacement parts for more than ten years, to improve their production and performance. All the cylinders are entirely engineered in Italy by Athena�s R&D Department which has a strong internal know-how and cutting-edge tools to design and test each piece. They are coated with motor-nicksil, a nickel-silicon coating developed by Athena to obtain smoothness and optimal wear resistance.
