Product Details

The Vortex 765ZK-42 is a 42-tooth steel rear sprocket designed as a direct OEM-style replacement for sport and street motorcycle applications. Manufactured by Vortex Racing, a trusted name in motorcycle drivetrain components, this sprocket delivers reliable performance and durability for everyday riding and track use alike.

Constructed from high-quality chromoly steel, the 765ZK-42 offers excellent wear resistance and long service life compared to standard OEM sprockets. The precision-cut teeth ensure smooth, consistent chain engagement and reduced drivetrain noise.

Key Features:

  • 42 teeth for optimized acceleration and gear ratio tuning
  • Heavy-duty chromoly steel construction for maximum durability
  • Precision CNC-machined teeth for smooth chain engagement
  • Direct OEM-replacement fit — no modifications required
  • Compatible with standard motorcycle drive chain
  • Corrosion-resistant finish for extended service life
