Product Details

The Vortex 491AZB-40 is a 40-tooth, 520-pitch black anodized aluminum rear sprocket engineered for performance motorcycle applications. Precision-manufactured to exacting standards, this sprocket delivers a significant weight savings over OEM steel units, reducing rotating mass for improved throttle response and acceleration.

Key Features:

  • Material: Lightweight 7075 T6 aluminum — significantly lighter than stock steel sprockets
  • Chain Pitch: 520
  • Tooth Count: 40 teeth
  • Finish: Black anodized for corrosion resistance and lasting appearance
  • Manufacturing: 100% CNC machined in the USA to tight tolerances
  • Alloy: Specially formulated per Vortex specifications for optimal strength-to-weight ratio
  • Tooth Design: Vortex's unique tooth profile promotes smooth chain engagement and increases sprocket longevity

Vortex Racing rear sprockets are a trusted choice among both track-day enthusiasts and professional racers. The reduced rotating mass of this aluminum sprocket translates directly to sharper acceleration and more responsive handling compared to heavier OEM alternatives. Compatible with standard 520-pitch chains and designed to meet precise fitment requirements for supported applications.

Product looks good and delivery was faster than expected. Thanks

I cant say any thing about the product yet, I haven't had a chance to analyze any boats yet with it. just got it yesterday. other then that i am happy with the order and shipping speed. the only reason for customer service was to verify the order.

Everything arrived as expected.
