Front Sprocket for Robinson Output Shaft | Countershaft Sprocket

If your motorcycle is equipped with a Robinson Output Shaft you will need one of these sprockets for proper fitment FITMENTS Suzuki Hayabusa / All Years Nickel-Chrome-Molybdenum Alloy Steel / 18 & 19 Tooth Available Silver Steel / 16 – 20 Tooth Available Suzuki GSX-R1000 / 2001-2008 Black Steel / 16 – 18 Tooth Available   MATERIALS Nickel-Chrome-Molybdenum Alloy Steel Front sprockets made from case-hardened and core refined 655M13 nickel-chrome-molybdenum alloy steel for the ultimate combination of strength and hardness Precision CNC machined to extremely tight tolerances for maximum performance Black Steel Constructed of the same great quality and specifications that the Japanese OEMs have trusted and used since 1946 Parkerizing surface treatment prohibits rust and corrosion, building resistance against those agents, resulting in a longer lasting, better appearance Most race applications feature drilled weight-reduction holes (depends on application/tooth size) Manufactured from case-hardened chromoly steel for unparalleled strength and durability Silver Steel On the surface they feature a dazzling zinc coating and weight reducing holes. Beneath the surface they feature precision machined and induction hardened steel. Unlike heat treated steel, the process of induction hardening heats the steel using a controlled electrical current. This method allows Vortex to manufacturer a quality sprocket with extremely tight tolerances. Induction hardened steel Offers improved concentricity which provides a stronger, quieter and longer-lasting sprocket Drilled for weight savings Corrosion-resistant plating
