APRILIA RS 125 GRADE A 53.97mm NIKASIL BORE
Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% silicon content depending on the application. They 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 diamond tools to achieve specific surface finishes. Each piston undergoes manual and automatic quality control. Vertex pistons are coated with a black Molybdenum Bisulphite coating for break-in and friction reduction. A new Phosphate Coating, developed from Formula One engine technology, offers increased hardness, surface porosity, and superior adhesion for the Molybdenum Coating, doubling its durability. This Nikasil bore cylinder has a 53.97mm bore size.

FULL DESCRIPTION
Vertex High-Performance Piston for Nikasil Bores
Upgrade your engine performance with this premium Grade A Vertex piston, specifically engineered for precision and durability. Designed to meet the demanding requirements of high-performance engines, this 53.97mm piston offers superior thermal stability and reduced friction for an optimized ride.
Advanced Manufacturing and Material Quality
Vertex pistons are manufactured using exotic Low-Ex (low expansion) silicon-charged aluminium alloys, with silicon content tailored to the application. Using sophisticated gravity casting and hydraulic forging processes, each piston blank is refined through a high-tech automated heat treatment system to ensure maximum material integrity and strength.
Precision Engineering and Durability
Every piston is machined using state-of-the-art CNC technology and diamond-tipped tools to achieve exact tolerances and specific surface finishes. To enhance longevity, these pistons feature a dual-layer coating system:
- Molybdenum Bisulphite Coating: A black surface treatment designed to assist with the initial break-in process while significantly reducing internal friction during engine operation.
- Phosphate Coating: Borrowing technology from Formula One engines, the all-over phosphate coating increases surface hardness and provides a micro-porous texture. This superior base layer ensures the molybdenum coating adheres more effectively, doubling the overall durability of the piston surface.
