Vortex 625ZB-50 530 Aluminum Rear Sprocket 50-Tooth Black

The Vortex 625ZB-50 is a 530-pitch, 50-tooth aluminum rear sprocket finished in a striking black anodized hard-coat. Engineered for performance street and track riders, this sprocket delivers a measurable reduction in rotating mass compared to steel alternatives, helping translate more engine power directly to the rear wheel.

• 50 Teeth — taller gearing option for improved low-end torque and acceleration
• Aerospace-Grade Aluminum Construction — lightweight material reduces rotational mass for improved throttle response
• Black Hard-Coat Anodized Finish — durable surface treatment resists corrosion and wear while providing an aggressive appearance
• Vortex Patented Tooth Design — unique saber-tooth profile increases sprocket longevity and optimizes chain engagement
• CNC Machined in the USA — precision manufacturing ensures tight tolerances and consistent fit
• Lightening Cutouts — strategically placed weight-reduction pockets further minimize unsprung and rotating mass
