Vortex 720ZK-50 Steel Rear Sprocket Pitch Sprockets - 520 50-Tooth

The Vortex 720ZK-50 is a precision-manufactured steel rear sprocket featuring a 520 pitch and 50 teeth, designed as a direct-fit replacement or performance gearing upgrade for compatible motorcycles. Built from hardened carbon steel, this sprocket delivers the strength, wear resistance, and consistent power transfer that Vortex Racing is known for.

The electro-plated satin finish provides corrosion resistance, while precision-cut weight-reduction slots help minimize rotating mass for improved throttle response. Induction-hardened teeth maintain their shape under demanding conditions, ensuring reliable chain engagement mile after mile.

Key Features:

• 520 pitch rear sprocket — 50 teeth
• Hardened carbon steel construction for long-lasting durability
• Electro-plated satin finish for corrosion resistance
• Precision weight-reducing cutouts to lower rotating mass
• Induction-hardened teeth for consistent chain engagement
• Direct OEM replacement or performance gearing upgrade
• Manufactured by Vortex Racing to precise tolerances

The Vortex 720ZK-50 steel rear sprocket is an ideal upgrade for riders seeking increased durability over aluminum sprockets without sacrificing the performance benefits of reduced rotating mass. A higher tooth count like 50T provides increased low-end torque and improved acceleration compared to stock gearing.
