Product Details

The Vortex 251AS-42 is a high-performance steel rear sprocket designed for sport bikes requiring a 520-pitch chain. Manufactured from durable carbon steel, this 42-tooth sprocket features an electroplated satin black finish that resists corrosion while maintaining a sleek appearance.

Key Features:

  • Premium carbon steel construction for exceptional durability
  • Heat-treated hardened teeth for extended wear life and many miles of reliable service
  • Electroplated satin black finish provides corrosion resistance
  • Cupped design reduces weight from the tooth ring to body without sacrificing strength
  • 520-pitch configuration with 42 teeth
  • Ideal for chain conversion applications (530 to 520 or 525 to 520)

This sprocket is engineered to deliver the perfect balance of strength and weight reduction. The strategic cupping design removes excess material while maintaining structural integrity, making it an excellent choice for riders looking to optimize performance. The hardened tooth profile ensures consistent power transfer and longevity, even under demanding riding conditions.

SOME OF THE BUTTONS ON THE WEBSITE WERE "HIDDEN" OR POPULATED BEHIND THE FIELD FOR ENTERING YOUR CITY. LUCKY AFTER 10 MINS OF LOOKING AT WHY IT WAS NOT ACCEPTING MY ORDER I NOTICED A SLIGHT EDGE OF IT POPPING OUT UNDER THE CITY FIELD. OTHERWISE IT WAS AN O.K. EXPERIENCE.

Thank you
