Product Details

The Vortex 525AZR-40 is a high-performance CAT5 aluminum rear sprocket engineered for 525-pitch drive chain applications on sport and performance motorcycles. Manufactured from aerospace-grade 7075-T6 aluminum, this sprocket delivers an ideal balance of lightweight construction and exceptional durability for both street and track use.

Key Features:

  • 525 Chain Pitch — designed for use with all standard 525-pitch drive chains
  • 40 Teeth — stock-replacement or performance-tuned tooth count for optimized gear ratio
  • 7075-T6 Aerospace Aluminum Construction — high-strength alloy reduces unsprung rotational mass compared to steel sprockets
  • Hard Anodized Finish — corrosion-resistant anodized coating for long service life
  • Precision Laser-Cut Teeth — CNC-machined to tight tolerances for smooth, quiet chain engagement
  • Lightweight Design — significantly lighter than OEM steel sprockets, improving throttle response and acceleration
  • Drilled Lightening Holes — further reduce overall weight without sacrificing structural integrity

Vortex sprockets are manufactured to exacting standards and trusted by professional racers across Supercross, Road Racing, and Flat Track disciplines. The 525AZR-40 is a direct bolt-on replacement that maintains OEM bolt patterns and carrier compatibility, making it a straightforward upgrade for riders seeking improved performance over the factory sprocket.

Saia is a horrible freight company. I used to deal with them at my previous job as a shipper. Box had a little damage, paint is rubbed off in a couple areas and swivel wheel assembly was bent. I was able to get it straight. Hopefully it will roll ok once it has weight on it. Not something I would expect for a $1500 item. I had to call Saia several times because I was getting a runaround on the delivery, they kept telling me they would schedule a delivery time. Never did, it showed up at my house unexpected, luckily my wife was still home. Seems like a good product though

Great pricing

I got an exact replacement for the anchor pulley I broke so I could use the same mounting holes on my boat.

Super easy!

Very easy, product description great
