Vertex Piston Kit

Vertex is the original equipment (OE) supplier of two-stroke pistons for KTM, known for its exceptional quality and performance. These gravity-cast pistons are made from premium aluminum alloys with a 12-21% silicon content.

The high silicon content helps control thermal expansion, which occurs when the engine reaches operating temperatures. By reducing this expansion, Vertex pistons maintain tight tolerances, offering better power output, lower noise, and a longer lifespan. The increased silicon also minimizes wear on the piston skirt, further extending the piston’s life. Additionally, each piston is coated with a unique Molybdenum Disulfide (MOS2) coating, which facilitates the break-in process and reduces wear over time.

Vertex Gasket Kit

Manufactured in the U.S.A., the Vertex Gasket Kit uses the latest materials and production technology to meet Vertex’s high standards. These gaskets are designed to prevent leaks and provide long-lasting performance for your rebuild. The kit includes head, base, and exhaust gaskets, valve seals, O-rings, and other essential gaskets to complete your top-end rebuild.
