Product Details

The Vortex 825-42 is a 42-tooth, 530-pitch aluminum rear sprocket designed specifically for motorcycles equipped with Marvic and Galespeed aftermarket wheels. Engineered for performance riders and racers, this sprocket delivers a lightweight, durable drivetrain upgrade over a standard steel sprocket.

The 825 bolt pattern is purpose-built for aftermarket wheel fitment, featuring a 6-bolt, 100mm bolt circle with 10.5mm bolt holes and an 80mm center hub diameter — the non-OEM specification used by Marvic and Galespeed wheels. The silver anodized finish provides corrosion resistance while keeping the classic aluminum look.

Key Features:

  • 42 teeth, 530 pitch — direct replacement for Marvic and Galespeed wheel applications
  • CNC machined from a specially formulated aluminum alloy per Vortex specifications
  • 100% manufactured in the USA
  • Silver anodized finish for corrosion resistance
  • Patented Vortex tooth design for extended sprocket longevity
  • Lightweight construction reduces rotating mass for improved throttle response
  • Bolt pattern: 6-bolt, 100mm bolt circle, 10.5mm bolt holes, 80mm hub diameter

The Vortex 825-42 is the go-to choice for riders running Marvic or Galespeed wheels who demand a precision-machined, race-proven rear sprocket without compromising on weight or durability.
