Vortex and RK MAX-O 520 Kit CBR 600RR 2003-2006
The Vortex 520 front sprocket is precision CNC machined, chromoly steel, nickel plated, and induction hardened. Vortex front sprockets have lightening holes to reduce rotating mass, which helps improve drive train performance. The sprockets are machined to a tight tolerance that does not exceed 0.1mm of runout, which is better than stock!
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.
The MAX-O chain is a high-quality O-ring chain at an unbeatable price for the quality offered. With 8500 pounds tensile strength, the 520 MAX-O chain is suitable for street motorcycles up to 750cc. It comes with a clip-style link and a rivet link. We strongly recommend using the rivet link, especially for track and racing use. Made in Japan.
This is a 120 link chain and will need links removed to fit properly.
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.
