HONDA NSR JC22 KY4 CRM 125 GRADE B 53.97mm TWIN RING PISTON
Vertex pistons are manufactured using Low-Ex Silicon aluminium alloys with 12%, 18%, or 21% silicon content depending on the application. The manufacturing process involves gravity casting or hydraulic forging, followed by a heat treatment process using an automatic HT implant with solubilization by quench in hot water. Machining is performed using CNC machines and diamond tools to achieve specific surface finishes. Each Vertex piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with Molybdenum Bisulphite for break-in and friction reduction, and newer pistons feature an all-over Phosphate Coating for increased hardness and superior adhesion of the Molybdenum Coating, doubling its durability. This product is a twin ring piston with a 53.97mm bore size and is Grade B.

FULL DESCRIPTION
High Performance Twin Ring Piston for 125cc Engines
Upgrade your engine reliability with this premium grade Vertex piston. Engineered for precision and durability, this component is designed to meet the rigorous demands of high-performance riding. Vertex pistons are trusted globally, having been utilized by top-tier racing organizations such as the Honda Gresini Race Team.
Advanced Manufacturing and Material Quality
Each piston is crafted from high-grade Low-Ex (low expansion) silicon-charged aluminium alloys. This material choice ensures superior thermal stability and structural integrity. Utilizing either gravity casting or hydraulic forging processes, the blanks undergo a sophisticated heat treatment in an automatic HT implant, followed by quenching in hot water to refine the material structure.
Precision Engineering and Surface Finishing
Every piston is machined using state-of-the-art CNC technology and high-precision diamond tools. This ensures exact tolerances and optimal surface finishes tailored to specific engine requirements. Before leaving the factory, each unit undergoes a comprehensive manual and automatic quality control inspection to guarantee peak performance and reliability.
Enhanced Durability Coatings
This piston features specialized surface treatments designed to improve longevity and performance:
- Molybdenum Bisulphite Coating: A black surface coating that assists during the initial engine break-in period and significantly reduces internal friction during cylinder operation.
- Phosphate Coating: Drawing from Formula One engine development, this coating provides a slight increase in surface hardness and introduces light surface porosity. This ensures superior adhesion for the Molybdenum coating, effectively doubling its durability for a longer service life.
