Product Details

The Vortex 120ZK-54 is a 54-tooth, 520-pitch CAT5 aluminum rear sprocket designed as a high-performance replacement for OEM steel sprockets. Built for street riders and track enthusiasts who want to shed unsprung weight without sacrificing durability, this sprocket is a direct upgrade over stock.

Key Features:

  • Material: Lightweight aerospace-grade 7075-T6 aluminum — significantly lighter than OEM steel
  • Construction: 100% CNC-machined in the U.S.A. to precise tolerances
  • Chain Pitch: 520
  • Tooth Count: 54 teeth
  • Finish: Black hardcoat anodized for corrosion resistance and long-lasting appearance
  • Design: Unique CNC-machined CAT5 profile for enhanced aesthetics and reduced weight
  • Application: Model-specific fitment — verify compatibility before ordering

The Vortex CAT5 series is a popular choice for riders looking to fine-tune their gearing ratio for improved acceleration or top-speed performance. A higher tooth count rear sprocket like this 54T unit increases low-end torque and acceleration responsiveness. Sold individually as a single rear sprocket.

Delivery was much sooner than expected

I ordered a tire from thmotorsports that the manufacturer had discontinued two years earlier and which I could not find anywhere else, without checking customer reviews first, something I never do. Had I checked reviews first I would never have placed the order as the reviews I read after placing my order were uniformly awful. But rather than call and cancel the order, which was my first impulse, I resisted the urge to do so and waited. A day later, the shipping update said my tire had shipped, so I waited. Another day later, the shipping update said my tire would arrive a day later by the end of the day so I waited. On the appointed day, the tire, exactly the tire I had ordered and which was unavailable anywhere else, arrived at the end of the day, brand new, in perfect condition and I was utterly amazed. Thank you, thmotorsports, I am so glad I did not look at your reviews before placing my order.
