Product Details

The Vortex 526AZK-45 is a lightweight CAT5 aluminum rear sprocket designed for performance-minded riders seeking a direct OEM replacement or a 520-pitch chain conversion upgrade. Machined entirely in the USA from a specially formulated aluminum alloy developed to Vortex's own specifications, this sprocket delivers a superior combination of low rotating mass and long-lasting durability.

Key Features:

  • CAT5 aluminum construction — lightweight aerospace-grade alloy reduces rotating mass for improved throttle response and acceleration
  • 100% CNC manufactured in the USA — machined to the tightest tolerances for precise fit and consistent performance
  • Vortex patented tooth design — saber tooth grooves and unique profile extend sprocket service life
  • Black anodized finish with contrasting silver machine cuts on sweeps and mud grooves for a premium appearance
  • Available in four colors (red, blue, gold, black) — color anodizing is applied exclusively to non-contact surfaces
  • 520 pitch — suitable for 520 OEM applications or 520 conversion builds
  • 45-tooth rear sprocket — ideal for fine-tuning final drive gearing

The Vortex CAT5 line is a favorite among track day enthusiasts and street riders alike. Its race-proven design and domestic manufacturing make the 526AZK-45 a top-tier upgrade over standard OEM steel sprockets.

Great

Shopping was easy. Shipping was fast the product quality was only issue but the problem was stuff I fixed.

Your website is great, but I only made this transaction because you cancelled my last one. I tried to order the Deezee brand box and your inventory was off. Hopefully I'll get this one, I really need my toolbox! Update- got the new box, it's just as advertised. It cost more than my original purchase and seems to be slightly lower quality, but still a good price vs. other sites. Definitely not the fastest shipping speed, but not outside of the usual time.

good

Quick and easy

This is my second purchase and it has all been good

Parts were easy to locate and at a great price thank you

Great so far!

satisfied

Ordering was easy, over the phone or online i was able to find all my parts on Autoplicity conveniently and my order was shipped out in a timely manner. I had concerns that were tended to by a quick phone call and great customer services reps.

So far, they did good getting my package to me...downfall it was opened from whoever was subcontracted to send it to me. however they promptly have provided me with a return slip and we will see where it goes from there. they were quick to help fix their problem as long as i had pictures of what was wrong. still cheaper than anywhere else.

Great!!

good service so far

Fast service even when shipping from the manufacturer. My product got to me in 3 days and it works great! Ordered an Odyssey PC1200 battery which was 20% cheaper than anyone else, with shipping included. Shipping information is a little slow on getting the tracking number, but their staff is efficient and friendly. Would definitely do business with them again.
