Belt-to-Chain Drive Conversion Kits

Wide Tire Conversion Kit

The belt drive on your Harley Dyna and Softail is very likely to fail if you have a highly modified engine. Replacement of belts is not only inconvenient, it is expensive and time consuming. While belts are clean running and don't need adjustments, "X-ring" chains provide an excellent, low-maintenance way to prevent failure in your drive train.

Chain drive is also an easy way to install a wider tire on your Dyna or Softail. You can easily install a 150/90 or larger tire on the rear of your bike with the chain drive conversion kit.

Nightrider is creating  complete Belt-to-Chain conversion kits for your Dyna or Softail. We will provide the appropriate gearing for performance or cruising, all sprockets, spacers and a high quality chain that will work with 170+HP engines.

Need to improve your acceleration or just want the wide tire look on your motorcycle, The Nightrider conversion kits are for you.
