Elevate the performance of your 85cc 2-stroke engine with the Vertex Cast Race Piston Kit. Engineered with advanced Vertex technology and a race-specific profile, this kit delivers exceptional durability and power for demanding riding conditions.
Description
The Vertex Cast Race Piston Kit is meticulously developed for peak performance in 85cc 2-stroke motorcycle engines. Each high-performance cast piston undergoes a rigorous T-5 hardening and tempering heat treatment cycle, significantly enhancing its strength and longevity. Crafted from a gravity cast aluminum alloy with an impressive 18% silicone content, this piston achieves an incredibly light yet robust construction, vital for high-revving applications. To ensure optimal break-in and extended operational life, every piston skirt is coated with a high-tech Molybdenum Disulphite (Moly) coating, reducing friction and wear. This complete kit includes everything you need for a straightforward installation: the piston itself, nitride-coated steel rings, a wrist pin, and circlips, ensuring a standard compression ratio and a precise 46.95 mm piston diameter, compatible with a 47.00 mm bore size.
