APRILIA RS 125 GRADE B 53.98mm NIKASIL BORE
Vertex pistons are manufactured using Low-Ex (low expansion) Silicon aluminium alloys (12%, 18% or 21% silicon content depending on application) produced via gravity cast or hydraulic forging. The material structure is refined using a hi-tech heat treatment process in an automatic HT implant with solubilization by quench in hot water. Machining is completed using the latest CNC machines and software with diamond tools, allowing specific surface finishes for different applications. Each Vertex piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with Molybdenum Bisulphite black coating to aid break-in and reduce friction. A new Phosphate Coating, developed following Formula One engine advancements, offers increased hardness, light surface porosity, and superior adhesion of the Molybdenum Coating for doubled durability. This is a Grade B, 53.98mm Nikasil bore.

FULL DESCRIPTION
High Performance Vertex Nikasil Bore Piston
Upgrade your engine reliability with this premium Vertex piston, specifically engineered for high-revving two-stroke applications. Designed for a 53.98mm Nikasil bore, this Grade B piston offers a precision fit to restore compression and optimize performance in your engine.
Advanced Manufacturing and Material Quality
Vertex pistons are crafted from exotic, low-expansion silicon-charged aluminum alloys, containing between 12% and 21% silicon depending on the application. Each piston blank is produced using either gravity casting or a hydraulic forging process. The structural integrity is further refined through a cutting-edge heat treatment process, utilizing automated solubilization and quenching to ensure maximum durability under extreme operating conditions.
Precision Engineering and Coatings
Every Vertex piston is machined using advanced CNC technology and diamond-tipped tooling to achieve the precise surface finishes required for high-performance engines. To ensure longevity and smooth operation, these pistons feature a multi-layer coating system:
- Molybdenum Bisulphite Coating: A specialized black coating that significantly aids in the break-in process and reduces internal friction during cylinder operation.
- Phosphate Coating: Drawing on Formula One development, this all-over treatment provides a slight increase in surface hardness and creates a light surface porosity. This technology ensures superior adhesion for the Molybdenum coating, effectively doubling its durability.
