Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% Silicon, depending on the application. They are produced using gravity cast or hydraulic forging processes and refined with a high-tech heat treatment in an automatic HT implant with solubilization by quench in hot water. Machining is performed 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. A new, all-over Phosphate Coating offers increased hardness and superior adhesion qualities, extending coating durability. This is a Grade A 47.44mm single ring replica piston.

FULL DESCRIPTION

High-Performance Vertex Replica Piston

The Vertex Grade A single ring replica piston is precision engineered to restore engine performance and reliability. Manufactured using advanced metallurgical processes, this piston is designed to meet the rigorous demands of high-performance two-stroke engines, ensuring optimal combustion and power delivery.

Key Features and Engineering

  • Advanced Alloy Construction: Crafted from high-quality Low-Ex (low expansion) silicon-charged aluminium alloys to maintain structural integrity under extreme thermal stress.
  • Precision Manufacturing: Produced through either gravity casting or hydraulic forging, followed by a state of the art heat treatment process for a refined, durable material structure.
  • CNC Machined: Finished using cutting-edge CNC technology and diamond-tipped tooling to achieve exacting surface tolerances and specific finishes.
  • Enhanced Durability Coating: Features a phosphate-based coating combined with a Molybdenum Bisulphite finish. This advanced layering increases surface hardness, reduces friction during the break-in period, and extends the lifespan of the piston coating.
  • Rigorous Quality Control: Each piston undergoes comprehensive manual and automatic inspections to guarantee that every component meets the highest quality and safety standards.

Whether you are performing a top-end rebuild or restoring your engine to factory specifications, this Vertex piston provides the professional-grade performance required for consistent results. Designed for optimal fit and efficient heat dissipation, it remains a preferred choice for riders seeking quality and longevity.
