Vortex 312ZR-30 Aluminum Rear Sprocket 30-Tooth

The Vortex 312ZR-30 is a 30-tooth aluminum rear sprocket precision-engineered for motorcycle riders seeking a lightweight, high-performance replacement or gearing upgrade. Part of Vortex Racing's 312ZR series, this sprocket is 100% CNC machined in the USA from a specially formulated aluminum alloy to exacting Vortex specifications.

Key Features:

• 30-Tooth Rear Sprocket — ideal for fine-tuning final drive gearing for top-end speed or acceleration
• Lightweight Aluminum Construction — reduces rotating mass for improved throttle response and overall performance
• 100% CNC Manufactured in the USA — ensures precise concentricity and consistent fitment
• Specially Formulated Alloy — per Vortex specifications for optimal strength-to-weight ratio
• Vortex Patented Tooth Design — saber tooth grooves increase sprocket longevity and improve chain engagement
• Anodized Finish — hard-coat anodizing provides corrosion resistance and long-lasting appearance
• Weight-Reduction Cutouts — strategically placed to minimize rotating mass without sacrificing structural integrity

The 312ZR-30 is part of Vortex's trusted lineup of racing-grade sprockets used by enthusiasts and competitors alike. Changing rear sprocket tooth count allows riders to dial in gearing for specific riding conditions — a lower tooth count (like 30T) shifts the power band toward higher top-end speed relative to a larger rear sprocket. Always replace the front sprocket, rear sprocket, and chain together for optimal wear life and performance.
