The complete ATHENA forged BIG BORE piston kit D.84.95 selection A Off-Road is designed to optimize the performance of Yamaha motorcycles, making it an essential component for off-road enthusiasts. This kit is the result of an innovative line of pistons specifically developed for 4-stroke off-road motorcycles, made with special high-performance materials through a reverse extrusion process.
The piston features a sintered molybdenum disulfide coating, applied via screen printing, which enhances smoothness and reduces friction and noise, ensuring smooth and quiet operation. The latest generation stainless steel rings, equipped with a CrN PVD coating, offer superior wear resistance and are designed to optimize conformity even under reduced tangential loads.
Developed in Italy and subjected to rigorous quality testing both on the dynamometer and on the track, these pistons ensure high performance and durability over time. With a wide range to fit most 4-stroke off-road motorcycles, the complete ATHENA piston kit represents a smart choice for those looking to enhance their off-road riding experience.
