Vertex Piston 18-22 KTM 300 EXC TPI 300cc Top End Piston Kit

The Vertex Top-End Piston Rebuild Kit VTK24244A provides all the necessary components for a full top-end rebuild in one convenient package. Each kit contains a high-quality Vertex cast replica piston, a complete set of piston rings, a wrist pin, circlips, and a full top-end gasket kit. For 2-stroke applications, a wrist pin bearing is also included. Vertex pistons are forged from premium 2618 aluminum alloy, offering exceptional strength and durability to withstand the demanding pressures of high-performance engines. The piston skirts feature a molybdenum disulfide coating to reduce wear and improve break-in. The included gasket kit comprises head, base, and exhaust gaskets, along with O-rings, crucial for maintaining a proper seal after cylinder and head removal. It is recommended to measure your cylinder bore prior to ordering to ensure perfect piston fitment (available in exact fit A, B, or C sizes).
