Made of 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 smooth profile ensures a regular flow and the perfect flame propagation. The piston for 4-stroke Off-Road motorcycles are made by reverse extrusion and produced numerical control (CNC) machines. Piston rings create less friction with the cylinder and therefore a higher performance. The segments included, Made in Japan, have a wear-resistant coatings (PVD or chromium nitride) to increase the retain and the durability.
