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.
