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 Big Bore cylinder kit 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.
