Vertex pistons are manufactured using Low-Ex silicon aluminum alloys. Pistons are made using gravity cast or hydraulic forging processes, then refined with a hi-tech heat treatment. Machining is completed using CNC machines and diamond tools. Every Vertex piston undergoes rigorous quality control. Vertex pistons are coated with a special Molybdenum Bisulphite black coating to aid break-in and reduce friction. Vertex has introduced a new Phosphate Coating which increases hardness and surface porosity, improving adhesion and durability of the Molybdenum Coating. This is a single ring, replica piston, 54.95mm oversize.

FULL DESCRIPTION
High-Performance Replica Piston by Vertex
Upgrade your engine's reliability and performance with this premium Vertex replica piston. Engineered for precision and longevity, this 54.95mm oversized piston is designed to meet the rigorous demands of two-stroke engine operation. Whether you are performing a top-end rebuild or restoring your machine to factory specifications, Vertex provides the quality components required to get back on the track.
Advanced Manufacturing and Material Quality
Vertex pistons are crafted from exotic Low-Ex (low expansion) aluminium alloys, specifically charged with 12%, 18%, or 21% silicon content depending on the application requirements. Each piston blank is created through advanced gravity casting or hydraulic forging processes. To ensure optimal structural integrity, the material undergoes a state-of-the-art heat treatment process in an automatic implant, featuring solubilization by hot water quench.
Precision Engineering and Coatings
Every piston is machined using high-precision CNC technology and diamond-tipped tooling to achieve exacting surface finishes tailored to the cylinder environment. To maximize durability and performance, these pistons feature a dual-layer coating system:
- Molybdenum Bisulphite Coating: A specialized black coating that assists during the critical piston break-in period and actively reduces friction during engine operation.
- Advanced Phosphate Coating: Inspired by Formula One engine technology, this surface treatment increases hardness and provides a light porosity that ensures superior adhesion of the Molybdenum coating, effectively doubling its durability.
Key Features
- Designed as a high-quality replica replacement part.
- +1.00mm oversize specification (54.95mm diameter).
- Single ring design for efficient engine performance.
- Rigorous manual and automatic quality control inspections on every unit.
- Engineered to resist thermal expansion and maintain consistent clearances.
