This is
only
a limiter, so
without
a fast CDI. You can buy a fast CDI separately here, or you can use it in combination with the original CDI – which you may have drilled a hole in for more speed.

After connecting this limiter you adjust it with the potentiometer to the desired
limited
speed between 0 and 65Km/h.

Then while driving you turn the limiter off with the remote control, if you see someone wearing a blue suit and a cap then (possibly while driving) you turn the scooter off very briefly with the ignition key and on again so that the limiter is on again and your scooter does not go any faster than you have set.

Suitable for all Piaggio/Vespa scooters with a 4 Stroke – 4 Valve engine including Sprint, Primavera, S, LX, New Fly etc.
