HONDA CR 250 2005-2007 GRADE A 66.34mm SINGLE RING RACE PISTON

Vertex Grade A 66.34mm Single Ring Race Piston

Enhance the performance and reliability of your engine with the Vertex Grade A 66.34mm single ring race piston. Engineered for competitive racing applications, this piston is designed to provide optimal combustion efficiency and superior durability under high-stress conditions.

Vertex utilizes exotic Low-Ex silicon-charged aluminium alloys, available in 12%, 18%, or 21% concentrations depending on the specific application requirements. These pistons are produced through precision gravity casting or hydraulic forging, followed by a state-of-the-art heat treatment process. This involves automated solubilization and hot water quenching to ensure a refined material structure and exceptional structural integrity.

Key Features

• Precision Engineering: Machined using advanced CNC technology and diamond tooling for exact tolerances and superior surface finishes.
• Advanced Coating: Finished with a Molybdenum Bisulphite black coating to reduce friction and assist during the initial engine break-in period.
• Enhanced Durability: Features an all-over phosphate coating that increases surface hardness and provides light porosity for superior adhesion of the Molybdenum layer, effectively doubling the durability of the coating.
• Quality Assurance: Each piston undergoes rigorous manual and automatic quality control inspections to meet professional racing standards.
• Race Ready: Single ring design specifically optimized for high-performance power delivery and reduced drag.

Whether you are performing a top-end rebuild or preparing for a race season, this Vertex piston offers the technology and consistency needed to maintain peak engine performance.
