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, followed by heat treatment in an automatic HT implant with solubilization by quench in hot water. Machining is performed on the latest CNC machines with diamond tools, allowing for specific surface finishes. Every Vertex piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with Molybdenum Bisulphite for break-in and friction reduction. A newer Phosphate Coating offers increased hardness, surface porosity, and superior Molybdenum Coating adhesion, doubling coating durability.

FULL DESCRIPTION
Vertex Grade D Single Ring Piston
The Vertex Grade D single ring piston is engineered for high-performance engine rebuilding, providing precision tolerances and superior durability. Manufactured using advanced Low-Ex aluminium alloys, these pistons are specifically designed to withstand the rigorous demands of two-stroke engine operation.
Vertex utilizes a sophisticated manufacturing process that includes either gravity casting or hydraulic forging, followed by a precision heat treatment in an automated implant to refine the material structure. This ensures optimal strength and resistance to thermal expansion under intense engine loads.
Key Features
- Advanced Alloy Composition: Constructed from Low-Ex (low expansion) Silicon charged aluminium alloys to ensure structural integrity and consistent performance.
- Precision Machining: Produced using state-of-the-art CNC technology and diamond-tipped tooling to achieve exacting surface finishes tailored for specific engine applications.
- Advanced Coating Technology: Features a Molybdenum Bisulphite black coating to reduce friction during the initial break-in period and throughout the piston life.
- Phosphate Coating: Incorporates a specialized phosphate surface treatment that increases hardness and provides superior adhesion for the Molybdenum coating, significantly extending the durability of the piston surface.
- Rigorous Quality Control: Each piston undergoes comprehensive manual and automatic inspection processes to guarantee high-level consistency and performance standards.
Engineered for reliability, the Vertex piston design incorporates the latest technological developments derived from high-level motorsport applications, ensuring your engine runs smoothly and efficiently. This 47.47mm Grade D piston is the ideal choice for riders looking to restore factory-level performance and longevity to their engine.
