In Youtube I once saw a procedure to unlock the speed on SuperSoco bikes. I think it was in a Frenh shop, and they jangled in a funny way with some of the handlebar commands (brakes, throttle, lights ...)
Try doing a little research. Good luck!
In some aspects I think the CPx is similar to the TS. Try to derestrict your scooter as the TS.
Good luck.
Deze handelingen heb ik al getest, ook mijn dealer heeft deze procedure gedaan.
Helaas zonder resultaat.
Max speed I was able to squeeze out of CPX with one battery (so lighter) slightly downhill in tunnel was 104km/h
Btw, all the 2020 models and newer have the derestriction disabled. This is confirmed by manufacturer. Only with a service cable you will be able to configure the limits.
