Vortex 253ZK-46 46-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 253ZK-46 is a 46-tooth, 520-pitch aluminum rear sprocket designed for sport and performance motorcycle applications. Built to Vortex Racing's exacting standards, this sprocket delivers a winning combination of reduced rotating mass and long-lasting durability.

Key Features:

• 46 teeth, 520 chain pitch — bolt-on replacement or gearing upgrade for compatible motorcycles
• Lightweight aluminum construction — significantly lighter than OEM steel sprockets to reduce rotating mass and improve throttle response
• 100% CNC manufactured in the USA — precision-machined to tight tolerances for consistent, concentric fit
• Specially formulated alloy per Vortex specifications — optimized for strength and longevity
• Clear coat finish — silver anodized/clear-coated to resist oxidation and corrosion
• Patented Vortex tooth design — unique profile engineered to extend sprocket life and reduce chain wear

Vortex Racing rear sprockets are a popular choice for street, track day, and club racing riders looking to fine-tune their final drive gearing. A 46-tooth rear sprocket increases the final drive ratio compared to most stock configurations, delivering stronger low-end acceleration and improved out-of-corner drive. As with all Vortex aluminum sprockets, regular chain cleaning and proper tension maintenance will maximize service life.
