Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% silicon content depending on the application. Pistons are made using gravity casting or hydraulic forging, followed by a heat treatment process 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. Each Vertex piston undergoes rigorous manual and automatic quality control. Pistons are coated with a special Molybdenum Bisulphite black coating for break-in and friction reduction. A new Phosphate Coating offers increased hardness and light surface porosity for superior Molybdenum Coating adhesion and durability. This piston is +1.00mm oversize with a 54.95mm diameter.

FULL DESCRIPTION
Vertex High Performance Oversize Single Ring Piston
The Vertex +1.00mm oversize single ring piston is engineered for riders seeking maximum reliability and performance. Precision manufactured to a 54.95mm diameter, this piston is designed to restore engine power and compression, making it an essential component for top end rebuilds where a cylinder bore has been enlarged.
Vertex utilizes advanced Low-Ex silicon-charged aluminium alloys to ensure minimal thermal expansion and consistent performance under extreme operating conditions. Using a combination of gravity casting and hydraulic forging, these pistons undergo a sophisticated heat treatment process that refines the material structure for superior strength and durability.
Key Features
- Advanced Alloy Technology: Manufactured from specialized silicon-charged aluminium alloys to manage thermal expansion effectively.
- Precision Machining: CNC machined using diamond tooling to achieve precise tolerances and specific surface finishes required for high performance applications.
- Phosphate Coating: Features a sophisticated phosphate coating that increases surface hardness and provides superior adhesion for the friction reducing top layer.
- Molybdenum Bisulphite Finish: Coated with a specialized Molybdenum Bisulphite layer to reduce internal friction and assist during the critical piston break in period.
- Rigorous Quality Control: Every component undergoes strict manual and automatic inspections to ensure the highest standards of engineering excellence.
- Durability Focused: The combination of advanced coating technology ensures the piston maintains performance and integrity throughout its service life.
Whether you are performing routine maintenance or a performance rebuild, Vertex pistons provide the professional grade quality necessary to keep your engine running at its peak.
