Vertex Cast Race Piston Kit - 47mm Bore - 85cc - Size A - 24446A

Upgrade your 2-stroke 85cc engine with the high-performance Vertex Cast Race Piston Kit, engineered for durability and optimized power delivery. This complete kit provides everything needed for a robust engine refresh, ensuring your motorcycle performs at its peak on the track or trail.

Description

The Vertex Cast Race Piston Kit is meticulously developed using advanced Vertex technology, featuring a specialized race shape profile designed for competitive environments. Each piston undergoes a rigorous T-5 hardening and tempering cycle, significantly enhancing its strength and longevity under extreme conditions. To minimize friction and accelerate the break-in process, the piston skirts are treated with a high-tech Molybdenum Disulphite coating, which also contributes to increased piston life. Crafted from a gravity cast aluminum alloy with an impressive 18% silicone content, this piston achieves an exceptional balance of being extremely lightweight yet remarkably strong. Designed specifically for 2-stroke 85cc engines, this kit ensures a precise fit with a 47.00 mm bore size and a 46.94 mm piston diameter. The kit comes complete with the piston, nitride coated steel rings, wrist pin, and circlips, providing a comprehensive solution for your engine rebuild or upgrade.
