Product Details

The Vortex 170ZO-39 is a 39-tooth aluminum rear sprocket from Vortex's VTX series, engineered for performance motorcycle applications. Precision CNC-machined from high-grade aluminum alloy, this sprocket delivers an optimal balance of light weight and durability for street and track use.

Key Features:

  • 39-Tooth Count – Provides the specific gear ratio needed for your application
  • CNC-Machined Aluminum Construction – Reduces unsprung rotating weight compared to steel sprockets
  • Precision Machined Teeth – Ensures smooth, quiet chain engagement and extended chain life
  • Lightening Cuts – Strategic material removal further reduces weight without sacrificing strength
  • Hard Anodized Finish – Resists wear, corrosion, and heat for long service life
  • Direct OEM Replacement – Bolt-on fitment with no modifications required

Vortex Racing is a well-established American manufacturer known for producing high-quality sprockets, rearsets, and other drivetrain components. The VTX aluminum rear sprocket line is a popular upgrade for riders looking to reduce drivetrain weight and improve throttle response. Pair with a Vortex front sprocket and quality chain for a complete drivetrain refresh.

I ordered the products, the products were delivered, and I was satisfied. A good transaction.

Great product

Great deal, great service.

shipping was very fast packed well no problems

Everything was fine, but UPS delivery my order several days late. Pretty common inmy area.

Only complaint is with UPS-paid for 2 day shipping, but evidently that does not include weekend. Ordered Wed night, THM processed on Thurs morning promptly. Didn't receive item till Monday. Other than that, A+ for THM.

Had the Parts I needed.
