Important Notice: Piston components and kits are subject to Size AND Fitment Specificity. You NEED TO MEASURE YOUR CYLINDER BEFORE ORDERING. If you use the wrong size piston/piston rings - you will damage your cylinder and we will not be liable. Return will NOT be accepted.

Produced with cutting-edge CNC machining tools that ensure dimensional tolerances of less than 0.01 mm - Athena pistons are made of a special high-performance aluminum alloy with high silicon content that guarantees the same reliability of the OE piston while providing greater resistance and excellent performance. The perfectly smooth profile ensures a regular flow and perfect flame propagation.

Athena engineers ensure advanced technical solutions and the highest quality standards equal to or better than those adopted in OE production to guarantee performance and reliability. Each piston is engineered in Italy by Athena's R&D department and is tested on engine dynamometer benches under progressive stress load and thereafter on track to validate its performance even in the most extreme conditions. The proven quality of Athena pistons is offered at an extremely affordable price.
