Product Details

The Vortex 312ZK-50 is a 50-tooth, 520-pitch CAT5 aluminum rear sprocket finished in a striking black anodized coating with contrasting silver machined accents. Engineered for performance riders and racers, this sprocket is 100% CNC manufactured in the USA from a specially formulated aluminum alloy developed to Vortex's own specifications.

Key Features:

  • Lightweight CAT5 Aluminum Construction: Reduces rotating mass compared to steel sprockets, improving throttle response and overall drivetrain efficiency
  • 100% CNC Manufactured in the USA: Precision machining ensures consistent tooth geometry, concentricity, and reliable fitment
  • Specially Formulated Alloy: Vortex-spec aluminum alloy balances strength and weight for demanding street and track use
  • Patented Unique Tooth Design: Vortex's proprietary tooth profile increases sprocket longevity and improves chain engagement
  • Black Anodized Finish with Silver Machined Accents: Provides corrosion resistance and an aggressive, race-ready appearance
  • 50 Teeth / 520 Pitch: Compatible with standard 520-pitch drive chains

The Vortex 312ZK-50 rear sprocket is an ideal upgrade for riders looking to reduce unsprung and rotating weight without sacrificing durability or performance. Vortex Racing sprockets are a trusted choice among professional and amateur racers worldwide.
