Product Details

The Vortex 313-55 is a 55-tooth, 420 chain pitch aluminum rear sprocket engineered for performance motorcycle applications. CNC machined in the USA from high-grade 7075-T6 aluminum, this sprocket delivers exceptional strength while significantly reducing rotating mass compared to steel alternatives.

Key Features:

  • Chain Pitch: 420
  • Tooth Count: 55 teeth
  • Material: 7075-T6 aerospace-grade aluminum
  • Finish: Silver anodized
  • Precision lightening holes to reduce unsprung and rotating weight
  • 100% CNC machined to tight tolerances for consistent concentricity
  • Manufactured in the USA

Vortex Racing sprockets are trusted by professional racers across AMA Superbike, Supercross, and motocross competition. The 313-55 is ideal for riders seeking increased low-end torque and acceleration through a higher rear tooth count. The 420 pitch makes this sprocket compatible with small-displacement and mini-sport motorcycle platforms.
