Vertex pistons are manufactured using Low-Ex Silicon aluminium alloys with 12%, 18%, or 21% silicon content depending on the application. They are produced using gravity casting or hydraulic forging, followed by a high-tech heat treatment process in an automatic HT implant with solubilization by hot water quench. Machining is performed using the latest CNC machines and software with diamond tools, achieving specific surface finishes. Each piston undergoes rigorous manual and automatic quality control. Vertex pistons feature a Molybdenum Bisulphite black coating for break-in and friction reduction, and a new Phosphate Coating for increased hardness, light surface porosity, and superior adhesion, doubling the coating durability. This piston is a big bore 145cc with a 57.95mm bore size.

FULL DESCRIPTION

Vertex Big Bore 145cc Piston Kit

Upgrade the performance of your machine with the Vertex Big Bore 145cc Piston Kit. Engineered for riders looking to increase displacement and power, this 57.95mm piston is manufactured using advanced aluminium alloys and cutting-edge production techniques to ensure durability and reliability under high-performance conditions.

Advanced Manufacturing and Material Quality

Vertex pistons are crafted from Low-Ex (low expansion) Silicon-charged alloys, utilizing gravity casting or hydraulic forging processes. The structural integrity of each piston is refined through a high-tech heat treatment process involving automatic solubilization and hot water quenching. Precision CNC machining and diamond tooling ensure exact tolerances and specific surface finishes tailored for high-output engine environments.

Enhanced Durability and Reduced Friction

This piston features a specialized Molybdenum Bisulphite black coating, which is essential for reducing friction during the break-in period and throughout the engine's operational life. To further improve longevity, Vertex incorporates an all-over Phosphate coating. This treatment provides a slight increase in surface hardness and a light porosity that promotes superior adhesion of the Molybdenum coating, effectively doubling its durability.

Key Features

  • Increased Displacement: Designed for 145cc big bore applications with a 57.95mm bore size.
  • Superior Alloy Construction: Utilizes high-silicon content alloys for thermal stability and low expansion.
  • Molybdenum Coating: Reduces friction and aids in smooth piston break-in.
  • Phosphate Coating: Enhances the adhesion and lifespan of the primary friction-reducing coating.
  • Strict Quality Control: Every unit undergoes rigorous manual and automated inspections to meet premium standards.
