Zero's final drive is a custom-designed Gates HTD (high torque drive) Poly Chain Carbon toothed carbon fiber belt.

  • It's never been available outside of Zero's parts system.
  • It's been the same part for 2012-2016 models.
    2017 models shifted to a wider belt that can accommodate more torque/loading.
