Description
The Vertex Cast Piston Kit for the KTM 85 SX 85cc is a high-quality OE replacement designed for durability and performance. This two-stroke piston is gravity cast from an aluminum alloy with 18% silicone content, making it both lightweight and strong. The piston undergoes a T-5 heat treatment process for added hardness and longevity. To enhance performance, the piston skirt is coated with a molybdenum disulphide (MoS2) coating, which reduces friction, speeds up the break-in process, and extends piston life. The kit includes a piston, rings, wrist pin, and circlips, providing everything needed for installation. Vertex is a trusted OEM supplier, known for producing reliable replacement pistons for motorcycles, ATVs, and other powersports applications.
