Vertex Cast Replica Piston Kit for 66.40 mm Bore

Upgrade your 2-stroke engine's performance and reliability with the Vertex 66.40 mm Cast Replica Piston Kit. Engineered for precision and durability, this piston kit provides an OE-quality replacement, ensuring optimal power delivery and extended engine life for your motorcycle.

Description

The Vertex Cast Replica Piston Kit is meticulously designed as an original OE form replacement, ideal for rebuilding your 250 cc 2-stroke engine. Each piston undergoes a rigorous T-5 hardening and tempering cycle, enhancing its structural integrity and resistance to extreme operating conditions. This robust heat treatment ensures that the 66.40 mm piston maintains its strength and shape under high stress, crucial for the demands of motorcycle engines. Furthermore, the piston skirts are treated with an advanced Molybdenum Disulphite (Moly) coating. This high-tech application significantly reduces friction during initial break-in, promoting faster seating of the rings and substantially increasing overall piston life. Crafted from a gravity-cast aluminum alloy with an impressive 18% silicone content, these pistons strike an optimal balance between being incredibly light and exceptionally strong. This specific alloy composition contributes to the piston's excellent thermal stability and wear resistance, making it a reliable choice for maintaining or restoring your engine's peak performance. As OEM replacements, both the replica pistons and their nitride-coated steel rings are engineered to meet or exceed original factory specifications.
