Vertex Cast Race Piston Kit for 85cc 2-Stroke

Elevate your engine's performance with the Vertex 85cc Cast Race Piston Kit, meticulously engineered for demanding 2-stroke applications. This high-performance piston kit delivers exceptional durability and power, making it an ideal choice for riders seeking an edge.

Description

Designed with Vertex's advanced technology and a race-specific profile, this cast piston kit ensures optimal combustion and power delivery for your 85cc 2-stroke engine. Each piston undergoes a rigorous T-5 hardening and tempering heat treatment cycle, significantly enhancing its strength and resistance to extreme operating conditions. The piston skirts are meticulously coated with a high-tech Molybdenum Disulphite finish. This specialized Moly coating reduces friction, promotes a faster break-in period, and extends the overall life of the piston, providing consistent, reliable performance throughout its lifespan.

Crafted from a gravity-cast aluminum alloy with an impressive 18% silicone content, this aluminum alloy piston strikes an optimal balance between being extremely lightweight and remarkably strong. This construction contributes to responsive engine characteristics without compromising on robustness. The complete Vertex 2-stroke piston kit includes everything needed for installation: the piston, rings, wrist pin, and circlips, ensuring a hassle-free upgrade for your motorcycle engine.
