Vortex 255AZB-46 CAT5 Aluminum Rear Sprocket 46-Tooth Black Anodized

The Vortex 255AZB-46 is a lightweight 46-tooth CAT5 aluminum rear sprocket finished in a striking black anodize with contrasting silver machined highlights. Designed and manufactured in the USA, this sprocket is a direct upgrade for riders seeking reduced rotating mass and improved throttle response compared to a stock steel unit.

Key Features:

• Lightweight CAT5 aluminum construction — reduces rotating mass for improved acceleration and throttle response
• 100% CNC machined in the USA — precision-manufactured to exacting tolerances
• Specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio
• Black anodized finish with contrasting silver machine cuts on the teeth and lightening pockets
• Vortex patented saber-tooth groove design — unique tooth profile increases sprocket longevity and chain engagement
• 46-tooth rear sprocket — adds low-end torque and improves acceleration compared to lower tooth counts

Vortex CAT5 sprockets are the benchmark in motorcycle performance drivetrain components, trusted by racers and street riders alike. The black anodized coating not only provides a bold visual accent but also helps resist corrosion and oxidation. As with all aluminum sprockets, regular chain cleaning and tension checks every 300–400 miles will maximize service life.
