The Vortex 338ZR-50 is a 520-pitch steel rear sprocket featuring 50 teeth, finished in a satin black electro-plated coating. Precision-engineered by Vortex Racing — a U.S.-based manufacturer trusted by professional racers worldwide — this sprocket delivers the durability and consistency demanded by serious street and track riders.

Key Features:

• 520 Pitch: Designed for motorcycles equipped with a standard 520-pitch drive chain
• 50 Teeth: Higher tooth count for increased low-end torque and acceleration
• Hardened Carbon Steel Construction: Resists wear over extended use without compromising structural integrity
• Satin Black Electro-Plated Finish: Provides corrosion resistance against the elements and maintains a clean appearance
• Lightening Holes: Strategic cutouts reduce rotating mass for improved throttle response and handling
