Athena 10-17 Honda CRF 250 R 81.95mm 4T Forged Piston

Athena, a leader in producing motorcycle spare parts for over 40 years, offers a new range of 4-stroke off-road forged pistons made by reverse extrusion. These pistons are produced with cutting-edge CNC machining tools, ensuring dimensional tolerances of less than 0.01 mm. They are made of a special high-performance aluminum alloy with a high silicon content, guaranteeing the same reliability as the OE piston while providing greater resistance and excellent performance. The perfectly smooth profile ensures a regular flow and perfect flame propagation. Some pistons' skirts are treated with a molybdenum disulfide coating, applied by screen printing, to further reduce friction and enhance performance and durability. This piston kit contains the piston, pin, the circlips, and the piston rings. All components are replaceable and interchangeable. All Athena products with greater displacement and power than provided by the road code of the user's country are intended exclusively for competitive use.
