Vortex 151ZR-49 CAT5 420 Pitch 49-Tooth Aluminum Rear Sprocket Red

The Vortex 151ZR-49 is a CAT5 M Tooth 420 pitch, 49-tooth aluminum rear sprocket finished in a striking red anodize with contrasting silver machined highlights. Designed for performance-minded riders, this sprocket delivers a noticeable weight reduction over OEM steel units, reducing rotating mass and improving throttle response and acceleration.

Key Features:

• 420 Pitch, 49 Teeth — direct-fit rear sprocket in the CAT5 M Tooth series
• Lightweight aerospace-grade aluminum construction machined from a specially formulated alloy per Vortex specifications
• 100% CNC manufactured in the U.S.A. for precise tolerances and concentricity
• Patented saber tooth groove design — Vortex's unique tooth profile increases sprocket longevity and chain engagement
• Red anodized finish with bright silver machined accents on the body (anodizing excludes tooth faces, mud grooves, and sweeps for durability)
• Reduces rotating mass compared to OEM steel sprockets for improved acceleration and handling

The Vortex CAT5 series is a trusted choice among racers and performance street riders alike. The 151ZR-49 is part of a wide tooth-count range, allowing riders to fine-tune their final drive gearing. For best results, replace the front sprocket and drive chain at the same time to ensure even wear across all drivetrain components.
