HONDA CR 250 1997-2001 GRADE D 66.37MM TWIN RING REPLICA
Vertex pistons are manufactured using Low-Ex aluminium alloys. The blank parts are made using gravity cast or hydraulic forging, then refined with a high-tech heat treatment. Machining is completed with the latest CNC machines and software using diamond tools to achieve specific surface finishes. Every Vertex piston undergoes rigorous quality control. Pistons are coated with a special Molybdenum Bisulphite black coating for break-in and reduced friction. A new Phosphate Coating is also available, offering increased hardness, light surface porosity, and superior adhesion qualities for durability. This is a twin ring replica piston with a 66.37mm bore size.

FULL DESCRIPTION
Vertex Replica Twin Ring Piston - Grade D 66.37mm
The Vertex Replica Twin Ring Piston is engineered to meet the demanding performance requirements of high-output engines. Utilizing advanced Low-Ex silicon-charged aluminium alloys, this piston provides exceptional structural integrity and thermal stability. Whether you are performing a top-end rebuild or a full engine restoration, this piston is designed to deliver reliable performance and durability.
Advanced Manufacturing and Material Quality
Vertex employs sophisticated manufacturing techniques to ensure every piston meets rigorous quality standards. The production process includes:
- Aluminium Alloy Composition: Manufactured using exotic Low-Ex silicon-charged alloys for optimal thermal expansion control.
- Precision Forging and Casting: Crafted using either gravity cast or hydraulic forging processes, followed by a state-of-the-art heat treatment in an automatic HT implant for refined material structure.
- CNC Machining: Machined with high-precision CNC equipment and diamond tooling to achieve specific surface finishes tailored to engine performance.
Enhanced Coating Technology
To reduce internal friction and assist during the critical engine break-in period, this piston features specialized coatings:
- Molybdenum Bisulphite Coating: A black surface treatment that minimizes friction and provides essential lubrication during the initial operation of the engine.
- Phosphate Coating: Borrowing from Formula One engine technology, the phosphate coating offers increased surface hardness and light porosity. This improves the adhesion of the Molybdenum coating, significantly extending the durability and wear resistance of the piston.
Every Vertex piston undergoes comprehensive manual and automatic quality control inspections to ensure consistent performance and reliability under heavy engine loads.
