HONDA CR 250 1997-2001 GRADE B 66.35MM TWIN RING REPLICA
Vertex pistons are manufactured using Low-Ex aluminum alloys with 12%, 18%, or 21% silicon, depending on the application. Pistons are made using gravity casting or hydraulic forging, followed by a heat treatment process. Machining is done with CNC machines and diamond tools, allowing for specific surface finishes. Every Vertex piston undergoes manual and automatic quality control. Pistons are coated with Molybdenum Bisulphite for break-in and friction reduction. Vertex also offers a Phosphate Coating with increased hardness and porosity for superior adhesion and durability. This is a Grade B, 66.35mm twin ring replica piston.
