HONDA CR 125 1992-1999 +0.50mm OVERSIZE 54.45mm TWIN RING REPLICA PISTON
HONDA CR 125 +0.50mm OVERSIZE 54.45mm TWIN RING REPLICA PISTON. Vertex pistons are manufactured using Low-Ex (low expansion) Silicon aluminium alloys with 12%, 18% or 21% silicon content depending on the application. Pistons are made using gravity cast or hydraulic forging processes, with material structure refined by a hi-tech Heat Treatment process in an automatic HT implant with solubilization by quench in hot water. Machining is completed using CNC machines and software with diamond tools, achieving specific surface finishes. Every piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with a special Molybdenum Bisulphite black coating for break-in and friction reduction. A new, all over, Phosphate Coating offers increased hardness, light surface porosity, and superior adhesion qualities of the Molybdenum Coating, extending durability.

FULL DESCRIPTION
Vertex Oversize Twin Ring Replica Piston
Maintain engine performance and reliability with the Vertex +0.50mm Oversize Twin Ring Replica Piston. Engineered to meet the exacting standards of high performance two-stroke engines, this piston is designed for those performing a top-end rebuild or cylinder repair that requires a larger bore diameter.
Advanced Materials and Engineering
Vertex manufactures these pistons using premium Low-Ex aluminium alloys, which are silicon-charged to provide optimal thermal expansion characteristics. Depending on the specific application, these alloys contain between 12% and 21% silicon. The blanks are produced through advanced gravity casting or hydraulic forging processes, followed by a state of the art heat treatment in an automatic HT implant for refined material structure and enhanced durability.
Precision Manufacturing
Each piston is machined on high-precision CNC equipment using diamond tooling. This manufacturing process allows for specific surface finishes that are tailored to the internal dynamics of the cylinder, ensuring efficient operation and longevity. Every component undergoes rigorous manual and automatic quality control inspections before leaving the factory.
Enhanced Coatings
To ensure peak performance, this piston features specialized coatings:
- Molybdenum Bisulphite Coating: A black surface finish that reduces friction during the critical break-in period and throughout the engine's lifespan.
- Phosphate Coating: Borrowed from Formula One technology, this all-over coating increases surface hardness and provides light porosity. This creates superior adhesion for the Molybdenum layer, effectively doubling the durability of the piston coating.
Key Features
