Vortex 491ZR-46 Red 46-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 491ZR-46 is a 46-tooth, 520-pitch CAT5 aluminum rear sprocket finished in Vortex's signature red anodized color with contrasting silver machined highlights. Designed as a direct-fit replacement or performance gearing upgrade, this sprocket is 100% CNC manufactured in the USA from a specially formulated aluminum alloy developed to Vortex's proprietary specifications.

Key Features:

• Lightweight CAT5 aluminum construction — reduces rotating mass for improved throttle response and acceleration
• 520 pitch — compatible with standard 520 drive chains
• 46 teeth — increases low-end torque and acceleration compared to lower tooth-count sprockets
• 100% CNC machined in the USA — precision manufacturing ensures concentricity and consistent fit
• Vortex patented saber tooth groove design — unique tooth profile increases sprocket longevity and chain engagement
• Red anodized finish with silver machined accents — anodized coating resists corrosion and adds a distinctive appearance
• Lightening holes — strategically placed cutouts further reduce unnecessary rotating weight

Vortex Racing has been the preferred sprocket brand of racers and performance riders for decades. The 491ZR-46 delivers race-proven durability and precision in a streetable package, making it an excellent upgrade for riders looking to optimize their drive system gearing.
