Vertex pistons are made from Low-Ex aluminum alloys with 12%, 18%, or 21% silicon, depending on the application. They are produced using gravity casting or hydraulic forging. Vertex pistons undergo a specialized heat treatment process called solubilization, quenched in hot water. Machining is done using advanced CNC machines and diamond tooling to achieve specific surface finishes. Each piston is subjected to strict manual and automatic quality control. Vertex pistons feature a Molybdenum Bisulphite black coating for break-in and friction reduction. They also incorporate a new Phosphate Coating for improved adhesion and durability of the Molybdenum Coating. This piston is 66.34mm with twin rings.

FULL DESCRIPTION

Premium Grade A Vertex Twin Ring Piston - 66.34mm

Upgrade your engine performance with this precision-engineered Vertex Twin Ring Piston. Designed for riders who demand reliability and power, this 66.34mm piston is manufactured to meet rigorous quality standards, ensuring an ideal fit and superior performance for your motorcycle engine.

Advanced Manufacturing Technology

Vertex utilizes exotic Low-Expansion (Low-Ex) silicon-charged aluminium alloys to create these pistons. The material composition, containing 12%, 18%, or 21% silicon depending on the application, ensures exceptional thermal stability and durability. The production process involves sophisticated gravity casting or hydraulic forging, followed by a state-of-the-art heat treatment in an automated implant to refine the material structure for maximum strength.

Precision Engineering and Durability

Each piston is finished using cutting-edge CNC machinery and diamond-tipped tooling to achieve the exact surface specifications required for high-performance use. To further enhance longevity, every unit features a dual-layer coating system:

  • Molybdenum Bisulphite Coating: A high-performance black coating that assists with the initial break-in period and significantly reduces friction during operation.
  • Phosphate Coating: Borrowing technology from Formula One engines, this all-over coating increases surface hardness and provides a light porosity that ensures superior adhesion of the Molybdenum layer, effectively doubling the coating durability.

Key Features

  • Precision Diameter: 66.34mm Grade A sizing for accurate clearance.
  • Twin Ring Design: Engineered to provide an excellent seal and consistent compression.
  • Rigorous Quality Control: Every piston undergoes extensive manual and automated inspections to ensure it meets the highest industry benchmarks.
  • Friction Reduction: Specialized coatings minimize wear and heat buildup, extending the life of both your piston and cylinder.
