Product Details

The Vortex 347ZK-57 is a 57-tooth steel rear sprocket designed for motorcycles using a 520 pitch chain. Engineered by Vortex Racing, a leader in high-performance drivetrain components, this sprocket delivers the durability and precision fitment demanded by both street riders and track enthusiasts.

Key Features:

  • 57 Teeth — increased tooth count for enhanced low-end torque and acceleration
  • 520 Chain Pitch — compatible with standard 520-series drive chains
  • Steel Construction — provides excellent wear resistance and long service life compared to aluminum alternatives
  • Precision CNC Machined — ensures accurate tooth profile and consistent chain engagement
  • Direct OEM Replacement — bolt-on fitment with no modifications required
  • Vortex Racing Quality — manufactured to strict tolerances for reliable performance

The 347ZK-57 rear sprocket is an ideal upgrade or replacement for riders looking to fine-tune their motorcycle's gearing for improved acceleration and responsiveness. Steel construction ensures this sprocket stands up to demanding riding conditions and extended service intervals.

Seamless as always!

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.

Good

I got what I needed quickly with no hassles. I would recommend Boatplicity to anyone with Johnson or Evinrude motors. Its not too often I have been as thoroughly pleased with online purchases as I am with this one. Kevin K. Long Lake, MN

Delivery was very fast. I didn't expect to receive it so soon.
