The maximum final speed can be freely preset here by means of rotary potentiometer on the CDI and activated or deactivated by the remote control. At each restart, the CDI is limited to the preset final speed. This means that the scooter is always in limiter mode after switching the ignition off and on. While driving, the limiter can be switched on and off as often as desired. The programming is very simple: with the throttle switched on, a test drive is made, if the maximum speed does not fit, the potentiometer is adjusted +/- as desired until the final speed is correct. The original 45km/h limiter is lifted with this CDI.
