Product Details

The Vortex 251AZKV4-42 is a 42-tooth aluminum rear sprocket from Vortex Racing's VTX series, engineered for performance street and track riders demanding lightweight precision drivetrain components. Machined from high-grade aluminum alloy and finished with a hard black anodized coating, this sprocket delivers excellent wear resistance while significantly reducing unsprung rotational mass compared to steel alternatives.

Key Features:

  • 42 Teeth – Direct replacement count for compatible applications
  • Lightweight Aluminum Construction – Reduces unsprung weight for improved acceleration and handling response
  • Hard Black Anodized Finish – Provides corrosion resistance and extended service life
  • CNC Machined – Precise tooth geometry for smooth, consistent chain engagement
  • VTX Series Design – Vortex's proven carrier-mount sprocket platform for secure, rattle-free fitment
  • Direct OEM Replacement – Bolt-on installation with no modifications required

Vortex Racing sprockets are manufactured to exacting tolerances and are a popular upgrade for sport bike, supersport, and track day enthusiasts looking to optimize gearing and reduce drivetrain weight. The 251AZKV4-42 is designed to work with standard motorcycle drive chains and is compatible with Vortex rear sprocket carriers.

Fast great service

Great job

THMOTORSPORTS responded and shipped my purchases of Auxbeam products very quickly. When received, everything looked to be in great shape. They also had the best prices of several vendors that I looked at. I would strongly recommend anyones next purchase to take a good look at THMOTORSPORTS as they definitely delivered on this purchase.

Couldn't be more pleased!

great prices

I would like to rate 5 stars. However item description doesn't contain 3 year old manufacture date.
