YAMAHA YZ 125 1998-2001 GRADE D 53.97mm SINGLE RING PISTON
Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18% or 21% silicon content. Pistons are made using gravity casting or hydraulic forging. The material structure is refined through a heat treatment process using an automatic HT implant with solubilization by quenching in hot water. Machining is completed using the latest CNC machines, software, and diamond tools, achieving specific surface finishes. Each piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with Molybdenum Bisulphite for break-in and friction reduction. A new Phosphate Coating offers increased hardness, light surface porosity, and superior adhesion qualities over the Molybdenum Coating, doubling its durability. This piston is 53.97mm with a single ring.

FULL DESCRIPTION
Vertex Grade D Single Ring Piston
The Vertex Grade D single ring piston is engineered to meet the demanding requirements of high performance engines. Designed with precision and durability in mind, this piston utilizes advanced metallurgical processes and cutting edge manufacturing techniques to ensure optimal performance and longevity for your engine rebuild.
Advanced Materials and Construction
Vertex manufactures their pistons using high quality Low-Ex silicon-charged aluminium alloys. Depending on the application, these alloys contain between 12% and 21% silicon to minimize thermal expansion. The production process involves either gravity casting or hydraulic forging, followed by a sophisticated heat treatment process that refines the material structure for superior strength.
Precision Machining and Quality Control
Each piston is machined using state of the art CNC equipment and diamond tipped tooling. This allows for specific surface finishes tailored to the requirements of the engine cylinder. To ensure the highest quality standards, every unit undergoes rigorous manual and automatic inspection throughout the manufacturing cycle.
Enhanced Coating Technology
To maximize performance, this piston features a dual-layer coating system:
- Molybdenum Bisulphite Coating: A specialized black coating that assists during the critical piston break-in period and reduces internal friction during operation.
- Phosphate Coating: Borrowing technology from Formula One engines, the phosphate base provides a slight increase in surface hardness and introduces light porosity. This creates superior adhesion for the Molybdenum layer, effectively doubling the durability of the protective coating.
Key Features
- Grade D sizing with a 53.97mm diameter.
- Single ring design optimized for reduced friction and high-rev performance.
- Low expansion alloy construction for consistent clearances.
- Advanced surface treatments for improved wear resistance and break-in protection.
