Product Details

The Vortex 821ZK-48 is a 48-tooth, 520-pitch black anodized aluminum rear sprocket engineered for serious street and track riders. 100% CNC-machined in the USA from a specially formulated aluminum alloy, this sprocket delivers an exceptional combination of lightweight performance and durability.

Key Features:

  • 48-Tooth / 520 Pitch – Compatible with standard 520 chain applications
  • Black Anodized Finish – Corrosion-resistant anodizing for long-lasting good looks and protection
  • 100% CNC Manufactured in the USA – Machined to precise tolerances for concentricity and consistent performance
  • Lightweight Aluminum Construction – Reduces rotating mass compared to steel sprockets, improving throttle response and acceleration
  • Vortex Patented Unique Tooth Design – Engineered tooth geometry extends sprocket life and reduces chain wear
  • Lightening Holes – Strategic material removal further reduces weight without compromising strength
  • Specially Formulated Alloy – Aluminum alloy developed to Vortex specifications for optimal strength-to-weight ratio

The Vortex 821ZK-48 rear sprocket is a direct upgrade for riders looking to optimize gearing for improved low-end torque, quicker acceleration, or track performance. As a trusted name in motorcycle racing, Vortex delivers race-proven quality in every sprocket.

Happy with results.

I needed an expensive part for my outboard motor's steering system, several of the internet sellers should out of stock/back ordered. Boatplicity showed the item in stock. I went on chat and was told the item was available. I paid the extra $9.99 for 2 day delivery. I ordered the $2000.00 item Wed. May 15 2024 at 1:00 pm. Fed Ex rang my door bell the next day at 11:30 am. I received that item less than 24 hours from the time I placed my order. That is as good as it gets !

Fast and easy!

Quick and easy process!

Awesome stock!!
