Description
Part #: S5F07800004A
Athena, leader in producing motorcycle spare parts for over 40 years, unveils its new range of 4-stroke off-road forged pistons made by reverse extrusion. Produced with cutting-edge CNC machining tools, which ensure dimensional tolerances of less than 0.01 mm, Athena pistons are made of special high-performance materials (nickel, silica, and aluminum alloys) 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.
MIA's Description
This piston offers reliability comparable to OE parts while providing enhanced resistance and performance. Its smooth profile contributes to regular flow and optimal flame propagation within the combustion chamber.
