Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% silicon content depending on the application. Pistons are made using gravity cast or hydraulic forging processes, followed by heat treatment. Machining is completed using CNC machines and diamond tools to achieve specific surface finishes. Each piston undergoes manual and automatic quality control. Vertex pistons are coated with Molybdenum Bisulphite for break-in and reduced friction. A new Phosphate Coating is also available, offering increased hardness and superior adhesion for the Molybdenum Coating, doubling its durability. This piston is a Grade C, 66.37mm single ring race piston.

FULL DESCRIPTION

High-Performance Vertex Race Piston

Upgrade your engine performance with this precision-engineered Vertex single ring race piston. Designed for riders who demand reliability and power, this piston is manufactured using exotic Low-Ex silicon-charged aluminium alloys, providing superior structural integrity and thermal resistance.

Advanced Manufacturing and Durability

Vertex utilizes a state of the art gravity cast or hydraulic forging process, followed by a sophisticated heat treatment cycle that refines the material structure for maximum durability. Every piston is machined using high-precision CNC equipment and diamond tooling, ensuring exact tolerances and optimal surface finishes.

Key Features

  • Advanced Alloy Composition: Constructed from Low-Ex silicon-charged aluminium to minimize thermal expansion and maintain optimal piston-to-cylinder clearance.
  • Phosphate Coating: Features an all-over phosphate coating that increases surface hardness and provides light porosity, significantly improving the adhesion and longevity of the Molybdenum Bisulphite coating.
  • Molybdenum Bisulphite Coating: A specialized black coating that reduces friction during operation and assists during the critical engine break-in period.
  • Rigorous Quality Control: Every unit undergoes strict manual and automatic inspection processes to ensure the highest manufacturing standards are met.
  • Engineered for Racing: Specifically designed to meet the demands of high-performance racing environments.

Technical Specifications

  • Type: Single Ring Race Piston
