Vertex Cast Replica Piston Kit - 54mm Bore - 125cc - Size D - 23749D

Upgrade your motorcycle's engine performance with the Vertex Cast Replica Piston Kit, specifically designed for 125cc 2-stroke engines. This high-quality piston kit offers an OEM-style replacement, ensuring reliable operation and enhanced durability.

Description

The Vertex Cast Replica Piston Kit is engineered to meet or exceed original equipment specifications for 125cc 2-stroke engines, featuring a precise 54.00 mm bore and standard compression ratio. Each piston undergoes a rigorous T-5 hardening and tempering heat treatment cycle, significantly enhancing its strength and longevity under demanding conditions. The piston skirts are meticulously coated with a high-tech Molybdenum Disulphite (Moly) layer. This advanced coating not only facilitates a faster break-in period but also substantially increases overall piston life by reducing friction and wear.

Constructed from a gravity-cast aluminum alloy with an impressive 18% silicone content, this piston kit delivers an exceptionally light yet remarkably strong component, ideal for motorcycle engine rebuilds. Unlike forged pistons, the cast design provides excellent thermal stability and consistent expansion characteristics. All included replica pistons and rings are direct OEM replacements, ensuring seamless compatibility and straightforward installation. This Vertex 54.00mm piston kit is a reliable choice for restoring peak performance to your 2-stroke motorcycle.
