Vortex 251AK 520 Rear Sprocket
Vortex 520 rear sprocket is manufactured to close tolerances from 7075-T6 aluminum alloy, then hard anodized for wear resistance, durability, and a beautiful, high-quality finish, which is black for this specific set, exactly as shown in the picture. This sprocket is lighter than the stock steel sprocket, which results in quicker acceleration due to the reduction in rotating mass.
Warning: Chain and sprocket sets must be installed by a qualified motorcycle mechanic with the proper tools and knowledge to safely complete the repair. Improper installation of these items could result in bodily injury or death.
