Product Details

The Vortex 775AZUV4-45 is a 45-tooth aluminum rear sprocket engineered for sport bike riders who demand lightweight performance without sacrificing durability. Built to Vortex's exacting standards, this sprocket is a direct upgrade over heavier OEM steel units.

Key Features:

  • Lightweight aluminum construction reduces rotating mass for improved acceleration and handling response
  • 100% CNC manufactured in the USA to precise tolerances
  • Specially formulated alloy developed per Vortex's proprietary specifications
  • Silver anodized finish provides corrosion resistance and a clean, race-ready appearance
  • Patented Vortex tooth design for extended sprocket longevity
  • 45 teeth for optimized drive ratio tuning

Vortex rear aluminum sprockets are a trusted choice among road racers and performance street riders. The reduced rotating mass compared to stock steel sprockets translates directly to sharper throttle response and more efficient power transfer to the rear wheel. Pair with a quality 520-pitch chain for best results.

Low friction purchase. Fast shipping. Very satisfied.

Your online system would not allow me to put my Alaska address for billing, even though the order was to be shipped to Texas. I sent repeated emails requesting a phone call and no one would call me or provide me a number to call.

Ordered a tire and received a tire. Took a couple days after shipping tag was created for it to actually ship, but it was a holiday week. Came pretty quick after the FedEx tracking was updated.

Returning customer from almost 17 years ago! I built a b16a and I bought all of the internals from you guys. Couldn't find my old account

Found what I was looking for

Quick and easy thank you

Fair prices , great tires

Average service
