Vertex Top-End Piston Kit for Suzuki RM250, 66.35 mm (VTK22854B)

Restore reliable top-end performance with the Vertex VTK22854B Top-End Piston Kit for Suzuki RM250 applications. This cast OE-replacement piston is manufactured from gravity-cast aluminum alloy with 18% silicone content, providing a dependable balance of strength, durability, and thermal performance for demanding two-stroke riding conditions. The kit is designed as a practical replacement solution for engine rebuilding and top-end service.
The piston receives a T-5 heat-treatment hardening and tempering cycle to support long-term durability under heat and load. Its skirt features a high-tech molybdenum disulfide coating that helps promote faster break-in and reduce friction during operation, contributing to extended piston life when installed and maintained according to the manufacturer’s specifications. The 66.35 mm piston size is engineered for compatible Suzuki RM250 applications, helping ensure proper fitment when matched to the correct cylinder and engine configuration.
This Vertex kit includes the essential components needed for a complete top-end piston replacement, including the piston, piston rings, wrist pins, circlips, top-end gaskets, and a wrist pin bearing. Each component works together to simplify installation and support a thorough engine refresh. Verify your motorcycle model, year, cylinder specifications, and required piston clearance before ordering to ensure the VTK22854B kit is appropriate for your application.
