Vertex Race Cast Piston Kit for 2-Stroke 125cc Engines

Elevate the performance and reliability of your 2-stroke 125cc engine with the Vertex Race Cast Piston Kit. Engineered for demanding conditions, this kit delivers exceptional durability and a precise fit, making it an ideal choice for enthusiasts seeking a high-performance cast piston solution.

Description

The Vertex Race Cast Piston Kit is meticulously developed using advanced Vertex technology, featuring a race-shaped profile optimized for superior power delivery and longevity in 125cc 2-stroke engines. Each piston undergoes a rigorous T-5 hardening and tempering heat treatment cycle, significantly enhancing its structural integrity and resistance to wear under extreme operating temperatures. For reduced friction and extended component life, the piston skirts are expertly coated with a high-tech Molybdenum Disulphite layer. This specialized coating ensures a faster break-in period and provides crucial protection against scuffing, critical for any 2-stroke piston replacement.

Constructed from a gravity cast aluminum alloy with an optimal 18% silicone content, this aluminum alloy piston kit achieves an impressive balance of lightness and exceptional strength. This manufacturing process results in a very strong yet lightweight piston (with a 53.97 mm diameter for a 54.00 mm bore) designed to withstand the rigors of racing and aggressive riding while maintaining a standard compression ratio. The complete kit includes the piston, high-quality nitride coated steel rings, wrist pin, and circlips, offering a comprehensive solution for your motorcycle engine piston overhaul.
