Vertex VTK22926B-1 Cast Replica Top End Piston Kit - Standard Bore 63.95mm, Standard Compression casual-wear-bags-pouches Kevlar and Biaxial Fiberglass compositesBore: 63. 95mm Compression: Standard Compression Sizing: Standard Bore All pistons are heat treated with a T 5 hardening and tempering cycle. All piston skirts are coated with a high tech molybdenum disulphite coating for faster break in time and increased piston life. Cast piston kits are gravity cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston. Forged pistons are forged from 2618
