HONDA CR 85 2003-2007 Grade B 47.45mm single ring replica piston. Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18% or 21% silicon content depending on the application. They are made using gravity cast or hydraulic forging and refined with a hi-tech heat treatment process in an automatic HT implant with solubilization by quench in hot water. Machining is completed using the latest CNC machines and software with diamond tools to achieve specific surface finishes. Every Vertex piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with a special Molybdenum Bisulphite black coating to aid break-in and reduce friction. Vertex also offers a new Phosphate Coating with increased hardness and porosity for superior adhesion and durability.

FULL DESCRIPTION
High Performance Vertex Replica Piston - 47.45mm
Upgrade your engine reliability and performance with this premium Vertex replica piston. Engineered for precision and durability, this piston is manufactured using advanced metallurgical processes to meet the demands of high-performance riding. Whether you are performing a routine top-end rebuild or restoring your engine to factory specifications, Vertex provides the quality components necessary for consistent power delivery.
Advanced Manufacturing and Material Quality
Vertex pistons are crafted from exotic Low-Ex (low expansion) silicon-charged aluminium alloys. Depending on the specific application, these alloys contain 12%, 18%, or 21% silicon to ensure thermal stability and reduce wear. The manufacturing process utilizes either gravity casting or hydraulic forging, followed by a sophisticated heat treatment in an automated HT implant. This process includes solubilization and a hot water quench to refine the material structure, resulting in a piston that is both lightweight and incredibly resilient.
Precision Engineering and Durability
Every piston is finished using state-of-the-art CNC machining and diamond tooling, ensuring exact tolerances and optimal surface finishes. To further enhance performance, these pistons feature a specialized Molybdenum Bisulphite black coating. This coating is designed to assist during the break-in process and significantly reduce friction during cylinder operation.
Additionally, this piston incorporates advanced phosphate coating technology. Inspired by Formula One engine developments, this phosphate layer provides a slight increase in surface hardness and a light porosity that allows for superior adhesion of the Molybdenum coating. This combination ensures that the protective finish lasts twice as long as standard coatings, providing extended component life.
