APRILIA RS GP 125 GRADE D 53.980mm 0.8mm RING NIKASIL BORE
Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% silicon depending on application. Piston blanks are made using gravity casting or hydraulic forging, then refined with automatic heat treatment and hot water quenching. Machining is done with the latest CNC machines, software, and diamond tools to achieve specific surface finishes. Each piston undergoes manual and automatic quality control. Vertex pistons feature a Molybdenum Bisulphite black coating for break-in and friction reduction. A new Phosphate Coating, developed from Formula One engine technology, offers increased hardness, light surface porosity, and superior adhesion for extended durability. This product is a GRADE D NIKASIL BORE piston, 53.980mm with a 0.8mm ring.

FULL DESCRIPTION
Vertex Grade D High-Performance Piston for Nikasil Bores
Engineered for precision and reliability, this Vertex piston is designed specifically for high-performance two-stroke engines requiring a Nikasil bore finish. Manufactured using advanced metallurgical processes, this Grade D piston features a 53.980mm diameter and is engineered to meet the demanding requirements of competitive racing applications.
Advanced Manufacturing and Material Quality
Vertex utilizes high-quality Low-Ex (low expansion) silicon-charged aluminium alloys, with silicon content tailored to the specific application for optimal thermal stability. The production process incorporates either gravity casting or hydraulic forging, followed by a state-of-the-art heat treatment cycle in an automatic implant to refine the material structure. This ensures superior strength and longevity under high-stress conditions.
Precision Engineering and Surface Treatment
Each piston is machined using high-precision CNC equipment and diamond tooling to achieve the exact surface finish required for maximum performance. To enhance durability and engine efficiency, this piston includes:
- Molybdenum Bisulphite Coating: A specialized black coating applied to the piston surface to aid in the break-in process and significantly reduce friction during cylinder operation.
- Phosphate Coating: Drawing on Formula One technology, the added phosphate layer provides a slight increase in surface hardness and improves porosity. This allows for superior adhesion of the Molybdenum coating, effectively doubling its durability.
- Rigorous Quality Control: Every unit undergoes a strict combination of manual and automatic inspections to ensure the highest standards of manufacturing precision.
This replacement piston is an ideal choice for engine rebuilds where quality, friction reduction, and long-term durability are the primary objectives.
