Product Details

The Vortex 823ZK-51 is a 51-tooth black hard-anodized aluminum rear sprocket engineered for performance motorcycle applications. Vortex Racing has been manufacturing top-quality racing drivetrain components in the USA since 1995, and this sprocket reflects that heritage of precision and durability.

Machined from a specially formulated aluminum alloy to Vortex's exact specifications, this rear sprocket delivers a significant weight reduction over OEM steel sprockets, helping reduce rotating mass for improved throttle response and acceleration. The black hard-coat anodized finish provides excellent corrosion resistance and a race-ready appearance.

Key Features:

  • 51-Tooth rear sprocket for modified gear ratio tuning
  • Lightweight CNC-machined aluminum construction reduces rotating mass
  • Black hard-coat anodized finish for corrosion resistance and durability
  • Specially formulated alloy per Vortex specifications for strength and longevity
  • Unique patented tooth design increases sprocket life
  • Lightening holes further reduce overall weight
  • 100% CNC manufactured in the USA
  • Direct OEM-style bolt pattern for straightforward installation

The higher 51-tooth count delivers increased low-end torque and improved acceleration compared to lower-tooth-count sprockets, making this an ideal upgrade for riders looking to optimize their gearing for track days, racing, or spirited street riding.

PERFECT!!!

Great site and prices.

I ordered the end links for quite a bit cheaper from THMotorsports that I was able to find them anywhere else including the manufacturer's website, Ebay & Amazon. I expected the shipping to take a week but within two days I was surprised with a package on my doorstep. So early, in fact, that I wondered what the package contained.

Very fast and easy best deal I found on my size tire

Great experience smooth transaction, I encourage everyone who is thinking about doing business, too pull the trigger!!

Skeptical at first cause of price difference compared to other sellers, researched site and after receiving as ordered and within 3 days, skepticism fully removed.

Easy to find what I needed!

Easy purchasing
