Vortex 527ZR-50 CAT5 530 Rear Sprocket 50-Tooth Red Aluminum

The Vortex 527ZR-50 is a 50-tooth, 530-pitch CAT5 aluminum rear sprocket finished in anodized red. Designed as a high-performance upgrade over OEM steel sprockets, it delivers a meaningful reduction in rotating mass for improved throttle response and acceleration.

Key Features:

• 7075 aerospace-grade aluminum construction — lightweight yet exceptionally strong
• 100% CNC machined in the U.S.A. to the tightest tolerances for perfect concentricity every time
• Saber tooth / unique tooth profile — engineered to reduce drag and friction while extending sprocket and chain life
• Color anodizing process — anodized first, then CNC machined, resulting in a vibrant red finish with silver highlights on the swept areas and teeth
• 530 chain pitch — compatible with standard 530 drive chains
• 50 teeth — taller gearing ratio for increased low-end acceleration and bottom-end torque
• Drilled lightening holes on most applications for additional weight savings
• Vortex patented sprocket design trusted by professional race teams worldwide

The CAT5 line is the standard choice in the road racing industry, combining race-proven performance with an aggressive look. Reducing rotating mass at the rear wheel multiplies the effect on overall drivetrain efficiency, freeing up horsepower and putting more power to the pavement.
