Product Details

The Vortex 775AZBV4-45 is a 45-tooth aluminum rear sprocket built to the exacting standards Vortex Racing is known for in the powersports industry. Designed as a lightweight, high-performance replacement for OEM steel sprockets, this sprocket delivers reduced rotating mass for improved throttle response and acceleration.

Key Features:

  • 45-Tooth, 520 Chain Pitch — precision-matched for 520-series drive chain applications
  • Silver Anodized Finish — corrosion-resistant anodizing protects the aluminum surface and provides a clean, high-quality appearance
  • 100% CNC Machined in the USA — manufactured to tight tolerances for concentricity and long-term durability
  • Specially Formulated Aluminum Alloy — proprietary Vortex alloy specification balances strength and weight reduction
  • Vortex Patented Tooth Design — unique tooth profile engineered to increase sprocket longevity and promote smooth chain engagement
  • Lightening Holes — strategically placed cutouts further reduce rotating mass without sacrificing structural integrity

The Vortex 775AZBV4-45 is the preferred choice for street riders and track enthusiasts who demand OEM-quality fitment with race-proven performance upgrades. Replacing a heavy steel OEM sprocket with this lightweight aluminum unit helps reduce unsprung and rotating weight, contributing to sharper handling and quicker acceleration.

I received my order of Shurflo replacement o-rings very quickly - sooner than expected. Unfortunately, I really only needed 1 or 2 o-rings, but they are only offered in a pack of 10. I'll never use 10 o-rings, so it was wasteful spending. I shopped other companies, and could not find packs of 1 or 2, and Boatplicity was the least expensive for what is available on-line.

Fast shipping. No complaints.

First time customer and very pleased with price and service.

Package was shipped out very fast. The packaging and materials were very good.

Quick service

Quick and easy. I can't tell if the tire is New or how much gas life is on it of the tire is used. Pictures make it look like the tire does not have much, if any, wear.
