The VERTEX 2-stroke piston kits are crafted using a gravity casting process with an aluminum alloy containing 18% silicon. The presence of silicon reduces thermal expansion at operating temperature, making the piston less prone to rattling and fractures. Additionally, silicon enhances the piston's wear resistance, thereby extending its lifespan. The kit includes the piston, piston ring(s), piston pin, and piston pin circlips. Available in three versions for 2-stroke engines: Replica (original form), Race (performance-enhancing), and Pro Race (forged specialty piston).
