Vortex 526AZR-44 CAT5 Aluminum 520 Rear Sprocket Red 44-Tooth

The Vortex 526AZR-44 is a lightweight CAT5 aluminum rear sprocket designed for 520-pitch chain drive systems. Precision-engineered for performance street and track riders, this 44-tooth sprocket is 100% CNC manufactured in the USA from a specially formulated aluminum alloy developed to Vortex's own specifications — delivering a strong, lightweight alternative to heavier OEM sprockets.

This sprocket features Vortex's patented saber tooth groove design, which promotes self-cleaning and extends sprocket longevity by reducing chain wear. The red anodized finish applies color to the face of the sprocket while leaving the sweeps, mud grooves, and teeth with bright silver machine-cut highlights — giving it a distinctive, race-ready appearance.
