Vertex Cast Race Piston Kit - 47mm Bore - 85cc - Size D - 24355D

Elevate your motorcycle's performance with the high-quality Vertex 85cc 2-stroke cast race piston kit. Engineered for demanding race conditions, this kit delivers exceptional durability and power, ensuring your engine runs at its peak.

Description

Designed with advanced Vertex technology, this 85cc 2-stroke cast race piston kit features a specialized race shape profile for optimal engine dynamics. Each piston undergoes a rigorous T-5 hardening and tempering cycle, significantly enhancing its strength and longevity under extreme operating temperatures. The piston skirts are meticulously coated with a high-tech Molybdenum Disulphite (Moly) layer, which not only facilitates a faster break-in period but also extends the overall piston life by reducing friction and wear. Constructed from a gravity cast aluminum alloy with an impressive 18% silicone content, this piston is engineered to be remarkably light yet exceptionally strong, capable of withstanding the rigors of competitive racing. With a precise bore size of 47.00 mm and a piston diameter of 46.97 mm, this standard size D piston kit is a perfect fit for your 85cc 2-stroke engine, providing reliable and consistent performance.
