HONDA CR 250 2005-2007 GRADE B 66.35mm TWIN RING REPLICA PISTON
Vertex pistons are manufactured using Low-Ex aluminum alloys with 12%, 18% or 21% silicon content depending on the application. They are produced using gravity cast or hydraulic forging processes, followed by heat treatment in an automatic HT implant with hot water quenching. Machining is performed on the latest CNC machines with diamond tools to achieve specific surface finishes. Every Vertex 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 Phosphate Coating has been introduced, offering increased hardness and light surface porosity for superior adhesion and durability of the Molybdenum Coating. This piston is a Grade B, twin ring, replica piston with a bore of 66.35mm.

FULL DESCRIPTION
Premium Vertex Twin Ring Replica Piston
The Vertex Grade B 66.35mm Twin Ring Replica Piston is engineered to meet the demanding requirements of high performance two stroke engines. Manufactured using advanced aluminium alloys and state of the art production techniques, this piston provides exceptional reliability and consistent engine performance.
Advanced Materials and Engineering
Vertex utilizes proprietary Low-Ex (low expansion) aluminium alloys, with silicon content specifically calibrated for this application. The blanks are produced through a precise gravity cast or hydraulic forging process, followed by a sophisticated automated heat treatment cycle. This ensures a refined material structure that delivers superior strength and heat resistance.
Precision Manufacturing
Every piston is machined using high tech CNC equipment and diamond tipped tooling. This level of precision allows for specific surface finishes optimized for internal engine environments, ensuring a perfect seal and long service life. Every unit undergoes rigorous manual and automated quality control inspections to meet strict engineering tolerances.
Enhanced Coatings for Performance
To maximize durability and minimize friction, this piston features a dual layer coating system:
- Molybdenum Bisulphite Coating: A high performance black coating applied to the piston skirt to facilitate a smooth break in period and reduce internal engine friction.
- Phosphate Coating: Borrowing technology from Formula One engines, the addition of a phosphate coating provides increased surface hardness and light porosity. This creates superior adhesion for the Molybdenum layer, effectively doubling the durability of the piston coating.
Key Features
