The PROX cast piston (ref. 01.2224.A) is designed for motocross riders looking for a reliable OEM part for their 125 engine. Machined from a specific aluminum alloy, this piston is engineered to minimize friction and ensure durability suitable for off-road conditions. Its design incorporates useful details for amateur competition: a domed head, optimized intake passage, and a skirt shaped for good stability in the bore.
The Mos2 treatment of the skirt helps reduce friction inside the cylinder, while the two lubrication holes promote an oil film on the exhaust area. This piston is ideal for the restoration or periodic maintenance of 125 cm3 motocross engines.
