Product Details

The Vortex 839AKV4-42 is a 42-tooth aluminum rear sprocket from Vortex's VTX series, engineered for performance-oriented motorcycle riders seeking a lightweight, durable alternative to stock steel sprockets. CNC-machined from high-grade aluminum alloy, this sprocket delivers an optimal balance of strength and weight savings for street and track applications.

Key Features:

  • 42-Tooth Configuration — alters final drive ratio for improved acceleration or top-speed tuning depending on application
  • CNC-Machined Aluminum Construction — significantly lighter than OEM steel sprockets, reducing unsprung and rotating mass
  • VTX Series Design — precision-cut teeth for smooth, consistent chain engagement and reduced drivetrain wear
  • Hard-Anodized Finish — resists corrosion and wear for extended service life
  • Direct OEM-Style Fitment — bolt-on installation using factory mounting hardware
  • Compatible with Standard O-Ring, X-Ring, and Z-Ring Chains

Vortex sprockets are a trusted choice among performance riders and racers worldwide. The 839AKV4-42 rear sprocket is an ideal upgrade for those looking to fine-tune gearing, reduce drivetrain weight, and improve overall performance over stock components.

No shop around had the prop I needed. We had plans to fish but I hit a rock. The prop came in time to get back out on the water and get out limit!! Arrived next day!

Everything was smooth and easy

Superfast shipping!!

Ordered a tire and received a tire. Took a couple days after shipping tag was created for it to actually ship, but it was a holiday week. Came pretty quick after the FedEx tracking was updated.

Very easy.
