Product Details

The Vortex 312ZB-39 is a high-performance CAT5 rear sprocket featuring 39 teeth and a durable black zinc finish. Precision-manufactured from high-quality steel, this sprocket is designed to deliver reliable power transfer and extended service life for sport and street motorcycles.

Key Features:

  • 39-tooth configuration for optimized gearing
  • Black zinc plating provides corrosion resistance and distinctive appearance
  • Precision-cut teeth ensure smooth engagement with chain
  • Heat-treated steel construction for maximum durability
  • Computer-designed tooth profile reduces chain wear
  • Lightweight design minimizes unsprung weight

Vortex CAT5 sprockets are engineered to meet or exceed OEM specifications, making them an excellent choice for replacement or performance gearing modifications. The black zinc coating offers superior protection against the elements while maintaining a clean, professional appearance.

Ordered four tires it was quick and easy and delivery of the tires was fast also, overall a good experience.

Quick online service. Easy website to use.

Quick service. Only concern was that your check out/payment process seemed clunky. My order went through but I also received emails saying it had failed. I called customer service and they confirmed that the order did process.

Great service
