Vortex 208K-48 Black Aluminum 520-Pitch 48-Tooth Rear Sprocket

The Vortex 208K-48 is a 48-tooth, 520-pitch aluminum rear sprocket finished in a black anodized coating. CNC-machined in the USA from a specially formulated aluminum alloy, this sprocket delivers the precision, durability, and weight savings that Vortex Racing is known for across street, track, and racing applications.

Key Features:

• 48-Tooth / 520-Pitch — direct-fit rear sprocket for compatible 520-chain drivetrains
• Black Anodized Finish — anodized coating applied before machining for the iconic two-tone machined look and corrosion resistance
• CNC Machined in the USA — 100% CNC manufactured to tight tolerances for consistent, reliable performance
• Lightweight Aluminum Construction — approximately half the weight of a steel sprocket, reducing rotational mass for improved throttle response
• Vortex Patented Tooth Design — unique tooth profile engineered to extend sprocket longevity and promote smooth chain engagement
• Specially Formulated Alloy — proprietary aluminum specification developed by Vortex Racing for optimal strength-to-weight ratio

Vortex aluminum sprockets are a popular choice for riders looking to fine-tune their gear ratio, reduce unsprung weight, or replace worn OEM sprockets with a higher-quality component. The black anodized finish provides both aesthetic appeal and added protection against oxidation. As with all aluminum sprockets, regular chain cleaning and proper tension maintenance will maximize service life.
