NKD Motors & Performance

What is the difference between the standard and X NKD motors? How is the performance calculated

There are three components that determine the output and performance of an electric motorcycle - motor, Powerpack and controller. The rated output of any of each component, does not determine the performance of the vehicle. In other words, the specifications of all three components are required to determine the maximum performance.
What is the difference between S and X motors? 
While the X motor is torquier than the standard NKD motor, they are both fast and the difference may not be discernible to the average rider.
FONZ compliance testing was completed at 100km/h therefore, the X Motor is speed limited to 100km/h for on-road riding.

NKD is built custom to your spec. Each powertrain setup will be different depending on the Powerpack, motor and controller setup.
