Product Details

The Vortex 921AV4-40 is a 420-pitch, 40-tooth aluminum rear sprocket engineered for performance-oriented mini bikes, pit bikes, and small-displacement motorcycles. Manufactured in the USA by Vortex Racing, this sprocket delivers the precision and durability that racers and enthusiasts demand.

Key Features:

  • 7075 T6 billet aluminum construction for an exceptional strength-to-weight ratio
  • 100% CNC machined to tight tolerances for superior concentricity and fit
  • 420 chain pitch compatibility — ideal for mini bikes and small-displacement applications
  • 40 teeth for optimized gearing performance
  • Lightening holes reduce rotating mass for improved throttle response
  • Unique saber tooth groove design increases sprocket longevity and chain engagement
  • Anodized finish provides corrosion resistance and lasting appearance
  • Made in the USA by Vortex Racing

Vortex Racing rear sprockets are a trusted choice across motocross, road racing, and minibike competition. The 921AV4-40 delivers a lightweight advantage over steel sprockets while maintaining the durability needed for demanding riding conditions.

Fast shipping great product!

Awesome experience! Thanks!
