The VERTEX TopEnd Piston Kit for KTM, HQV, GASGAS 2-stroke engines is designed with precision and durability in mind. These pistons are produced using gravity casting from an aluminum alloy containing 18% silicon. The high silicon content reduces thermal expansion at operating temperature, which minimizes the risk of piston slap and fractures. Additionally, silicon enhances the wear properties of the pistons, thereby extending their lifespan. The kit includes the piston, piston rings, piston pin, and piston pin clips. Available in three types: Replica (piston matches the original shape), Race (performance-enhancing design), and Pro Race (forged specialty piston). Ideal for motorcycle enthusiasts looking for reliable and high-performance engine components.
