Product Details

The Vortex 251AZUV4-45 is a 45-tooth aluminum rear sprocket engineered for powersports applications. Manufactured by Vortex Racing, a trusted name in high-performance drivetrain components, this sprocket is precision-machined from lightweight aluminum alloy to deliver an optimal balance of strength and weight savings over stock steel sprockets.

Key Features:

  • 45-Tooth Rear Sprocket – Provides tunable gearing for acceleration and top-speed optimization
  • Lightweight Aluminum Construction – Significantly reduces unsprung rotational mass compared to steel alternatives
  • Precision CNC-Machined – Tight tolerances ensure smooth chain engagement and extended sprocket life
  • Hard Anodized Finish – Resists corrosion and wear for long-lasting durability
  • Direct OEM Replacement Fitment – Designed to bolt on without modification
  • Part of the VTX Series – Vortex's line of performance-focused sprockets for street and track use

Vortex sprockets are a popular upgrade for riders looking to fine-tune their motorcycle's power delivery. A larger rear sprocket like this 45-tooth unit increases low-end torque and acceleration, making it an ideal choice for riders who prioritize corner-exit drive and street performance. Pair with a matching front sprocket and quality chain for best results.
