HONDA CR 250 1989-1994 1.1mm OVERSIZE 67.45mm TWIN RING REPLICA
Vertex pistons are manufactured using Low-Ex aluminum alloys. The pistons are made using gravity cast or hydraulic forging processes. The material structure is refined using a hi-tech heat treatment process. Machining is completed using the latest CNC machines and software with diamond tools. 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 which offers increased hardness and light surface porosity for superior adhesion and durability. This piston is 1.1mm oversize at 67.45mm and is a twin ring replica.

FULL DESCRIPTION
Vertex High-Performance Twin Ring Replica Piston
The Vertex Twin Ring Replica Piston is engineered for riders who demand precision, durability, and reliable performance. Manufactured using advanced metallurgical techniques, this piston is designed to meet or exceed OEM specifications, providing an ideal solution for engine rebuilds and performance maintenance.
Advanced Material Construction
Each piston is crafted from exotic Low-Ex (low expansion) aluminium alloys, with silicon content specifically calibrated between 12 percent, 18 percent, or 21 percent depending on the application requirements. The blanks are produced through either gravity casting or hydraulic forging, followed by a sophisticated heat treatment process in an automatic HT implant to refine the material structure for maximum strength.
Precision Engineering and Coatings
Vertex utilizes state-of-the-art CNC machinery and precision diamond tooling to ensure exact tolerances and optimal surface finishes. To enhance longevity and efficiency, every piston features a specialized Molybdenum Bisulphite black coating, which minimizes friction during operation and assists during the critical engine break-in phase.
Enhanced Durability
Taking inspiration from Formula One engine development, these pistons now include a comprehensive Phosphate Coating. This coating increases surface hardness and introduces light surface porosity, which ensures superior adhesion of the Molybdenum layer, effectively doubling the durability of the piston coating for extended service life.
