Vertex Cast Replica Piston Kit for 250cc 2-Stroke (66.40mm)

Enhance the performance and longevity of your 2-stroke engine with the Vertex Cast Replica Piston Kit. Engineered to precise OEM specifications, this kit provides a reliable and durable replacement solution for your motorcycle, ensuring optimal engine function.

Description

The Vertex Cast Replica Piston Kit is meticulously designed as an original equipment (OE) replacement, offering exceptional quality for your 2-stroke engine. Crafted from a gravity-cast aluminum alloy with an 18% silicone content, this piston achieves an outstanding balance of lightness and strength, crucial for high-performance applications. Each piston undergoes a T-5 heat treatment cycle, a specialized hardening and tempering process that significantly enhances its structural integrity and resistance to wear under extreme engine conditions. For improved break-in and extended piston life, the skirts are coated with a high-tech Molybdenum Disulphite (Moly) coating, reducing friction and ensuring smooth operation. This Vertex Cast Replica Piston Kit is specifically tailored for 250cc 2-stroke engines, featuring a precise 66.40mm bore size and a standard 'A' piston size. The nitride-coated steel rings are also OEM replacements, guaranteeing a perfect fit and seal, making this 2-stroke engine piston an ideal choice for restoring or upgrading your engine's internal components.
