Product Details

The Vortex 491AZB-50 is a 50-tooth CAT5 aluminum rear sprocket finished in a striking black hard-coat anodized finish. Designed for performance-minded riders, this sprocket delivers a winning combination of reduced rotating mass and exceptional durability — straight from one of the most trusted names in motorcycle drivetrain components.

Key Features:

  • Lightweight CAT5 aluminum construction — reduces rotating mass for improved throttle response and acceleration
  • 100% CNC machined in the USA — precision manufacturing for exact tolerances and consistent fit
  • Specially formulated aluminum alloy per Vortex specifications for optimal strength-to-weight ratio
  • Black hard-coat anodized finish — provides corrosion resistance and a clean, aggressive look with contrasting silver machine cuts
  • Vortex patented tooth design — unique saber tooth profile increases sprocket longevity and chain engagement
  • 50-tooth rear sprocket — increases low-end torque and acceleration for street and track applications

The Vortex CAT5 series is the racer's choice for aluminum rear sprockets. Switching to a larger rear tooth count like this 50-tooth sprocket increases acceleration and low-end pull, making it ideal for technical circuits or riders looking to enhance their bike's throttle response. Always ensure the sprocket pitch matches your front sprocket and chain.

Great price and quick delivery

I ordered a tire from thmotorsports that the manufacturer had discontinued two years earlier and which I could not find anywhere else, without checking customer reviews first, something I never do. Had I checked reviews first I would never have placed the order as the reviews I read after placing my order were uniformly awful. But rather than call and cancel the order, which was my first impulse, I resisted the urge to do so and waited. A day later, the shipping update said my tire had shipped, so I waited. Another day later, the shipping update said my tire would arrive a day later by the end of the day so I waited. On the appointed day, the tire, exactly the tire I had ordered and which was unavailable anywhere else, arrived at the end of the day, brand new, in perfect condition and I was utterly amazed. Thank you, thmotorsports, I am so glad I did not look at your reviews before placing my order.

All good, thanks.

VERY EASY TO ORDER AND CHECK OUT.
