Athena cast piston for Aprilia RX 50 95-04 (for Athena Big Bore Cylinder)

This Athena piston for Athena Big Bore cylinder is equipped with piston rings, which guarantee less friction with the cylinder and therefore a higher yield.
The kit includes, in addition to the piston itself, the piston pin, the piston pin rings and the ring kit. All these components are replaceable and interchangeable in case of need.

Athena, leader in motorcycle spare parts for over 40 years, offers a complete range of hot forged pistons using reverse extrusion for the main 2-stroke and 4-stroke off-road motorcycle models. Produced with state-of-the-art numerical control (CNC) machines, which ensure production dimensional tolerances of less than 0.01 mm, Athena pistons are produced in a special high-performance silicon-based aluminum alloy that ensures reliability equal to the original. and, at the same time, greater resistance and excellent performance. The perfectly smooth profiles thus ensure a regular flow and ideal propagation of the flame front.
Each piston, engineered in Italy by the Athena R&D department, is also subjected to severe bench and track tests to test its performance.

All Athena items produced in displacements and powers higher than those required by the road code of the user's country are intended for competitive use only. Athena declines all responsibility for any use of the product contrary to national standards.
