The Vortex 825KV4-40 is a high-performance aluminum rear sprocket designed for riders who demand precision, durability, and reduced rotating mass. Featuring 40 teeth and compatibility with 520 chain pitch, this sprocket is CNC-machined from lightweight 7075-T6 aluminum for an optimal balance of strength and weight savings over OEM steel sprockets.

Key Features:

  • Material: CNC-machined 7075-T6 aluminum for maximum strength-to-weight ratio
  • Tooth Count: 40 teeth
  • Chain Pitch: 520
  • Carrier Code: KV4 — Vortex-specific hub carrier fitment
  • Hard anodized finish for corrosion resistance and extended wear life
  • Precision-machined tooth profile for smooth, consistent chain engagement
  • Significant weight reduction compared to OEM steel sprockets
  • Ideal for street performance and track/racing applications

Vortex is a trusted name in the sport bike and racing community, known for producing sprockets that meet the demands of both weekend riders and professional racers.
