Vortex 520 Quick Acceleration Kit for 2019-2024 Kawasaki Ninja ZX6R 636 with 15/43 stock gearing. Supplied with RK MAX-O 520 chain shown in photo.


Front Sprocket:

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!


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.


Chain:

The RK 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 kit is shipped with a 120 link chain which will need links removed by your mechanic to fit the bike correctly. This kit should be installed by a qualified motorcycle mechanic with the proper tools and knowledge. Failure to install and maintain this kit correctly can lead to serious damage to the motorcycle, bodily injury, or death.
