Produced with cutting-edge CNC machining tools, which 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  guarantee the same reliability of the OE piston, while at the same time  providing greater resistance and excellent performance. The perfectly  smooth profile ensures a regular flow and the perfect flame propagation.\u003c\/p\u003e \u003cp\u003eSome  pistons’ skirts are moreover treated with a molybdenum disulfide  coating applied by screen printing which further reduce friction to  enhance performance and durability.\u003c\/p\u003e \u003cp\u003eAthena engineers ensure  advanced technical solutions and the highest quality standards equal to  or better than those adopted in OE production, so as to guarantee  performance and reliability.\u003c\/p\u003e \u003cp\u003eEach piston, engineered in Italy by Athena R\u0026amp;D department, is  tested on engine dynamometer benches under progressive stress load, and  thereafter on track to validate its performance even in the most extreme  conditions.\u003c\/p\u003e \u003cp\u003eThe proven quality of Athena pistons is offered at an extremely affordable price.\u003c\/p\u003e \u003cp\u003eThis  piston for Athena and OE cylinders is equipped with piston rings that  guarantee less friction with the cylinder and therefore a higher  performance.\u003c\/p\u003e \u003cp\u003eAthena takes care of the development of the pistons down to the  smallest detail: the rings are produced in Japan with wear-resistant  coatings (PVD or chromium nitride) to increase the retain and the  durability. The rings perfectly adapt to the cylinder liner even at low  tangential load.\u003c\/p\u003e \u003cp\u003eThis piston kit contains the piston, the pin, the  circlips, and the piston rings. All components are replaceable and  interchangeable in case of need.\u003c\/p\u003e \u003cp\u003eAll Athena products produced in  greater displacement and power than those provided by the road code of  the user's country, are intended exclusively for competitive use.
