Product Details

The Vortex 528CZR-45 is a CAT5 aluminum rear sprocket featuring 45 teeth for 525-pitch chain applications. Part of Vortex Racing's iconic CAT5 lineup, this sprocket is CNC machined from a specially formulated aluminum alloy to deliver an exceptional strength-to-weight ratio over stock steel sprockets.

The CAT5 process starts with anodizing the billet aluminum before CNC machining, resulting in the sprocket's signature two-tone appearance — a vibrant red anodized finish with bright silver machined highlights on the teeth and swept areas. This is not paint or a surface coating; the color is built into the aluminum itself for lasting appearance.

Key Features:

  • 525 Chain Pitch — designed for 525-series O.E.M. road applications
  • 45 Teeth — ideal for adjusting final drive gearing toward more low-end torque and acceleration
  • Lightweight CAT5 aluminum construction — reduces rotating mass for improved throttle response
  • 100% CNC manufactured in the USA to tight tolerances
  • Specially formulated aluminum alloy per Vortex Racing specifications
  • Saber tooth groove design — Vortex patented tooth profile increases sprocket longevity and improves chain engagement
  • Red anodized with contrasting silver machined accents — anodized first, then machined for a durable two-tone finish
  • Trusted by professional road racing teams worldwide

Vortex Racing has been producing the CAT5 sprocket design since 1995, making it one of the most proven and recognized sprocket designs in motorsport. The 528CZR-45 is an excellent performance upgrade or direct replacement for worn OEM sprockets on compatible 525-chain motorcycles.

Paypal made it quick & easy to order!

Very easy, so far.

These people are just awesome! I got my Thule Bike Rack for a fraction of the cost compared to everywhere else. Shipping was very fast and cheap but when I received it there were a couple of missing hardware parts. Thule wanted to make me ship the whole thing back. Rob Fratu of Autoplicity took control of the situation and got Thule to ship me the missing parts and some extras, all within a couple of days. I cant remember a better experience with a retailer.

Quick and easy to pay. I used my Amazon account

So far, so good. Just have to wait for the part to arrive.

Great prices

Ordered a K&N air filter from these guys because they about cut the cost to half what I found everywhere else. Planning on buying a few more items in the near future considering the savings.I'm bookmarking their page now. Motorcyclists I'd suggest doing the same ;)
