Product Details

The Vortex 120A42 is a lightweight aluminum rear sprocket designed for performance motorcycle and powersports applications using 420-pitch chain. Featuring 42 teeth, this sprocket is precision CNC-machined in the USA to the tightest tolerances in the industry, delivering race-proven reliability and performance.

Key Features:

  • 7075 T6 aerospace-grade billet aluminum construction for an optimal strength-to-weight ratio
  • Reduces rotating mass compared to stock steel sprockets, improving throttle response and acceleration
  • Silver anodized finish provides corrosion resistance and long-lasting appearance
  • Vortex patented tooth geometry engineered for optimized chain engagement, hold, and release
  • 100% CNC manufactured in the USA to exacting tolerances
  • Lightening holes further reduce weight without sacrificing structural integrity
  • Fits 420-pitch chain — common on mini bikes, pit bikes, and small-displacement sport motorcycles

Vortex Racing is a U.S.-based manufacturer trusted by professional racers across Motocross, Supercross, Road Racing, and Flat Track disciplines. The 120A42 rear sprocket is a direct performance upgrade for riders looking to shed drivetrain weight and sharpen acceleration response.

Found what I needed at a fair price. There was never an email confirming that my purchase was shipped so I had no way to track it or any idea when it would arrive. After I received my order I received an email stating that my purchase had been shipped but the information of when this took place was not included. Product was great, got it within a week, but communication to purchaser is lacking.
