With this out of the way, let’s talk about the restricted CDI’s found in some 50cc scooters. Tho, keep in mind that there might be an additional third party restriction installed to allow for riding your scooter model with a certain license. To get one thing straight: Only 50cc scooters have a restricted CDI. I have never heard of a bigger engine model with a restricted CDI which is being shipped like that (if you know please leave a comment). Why are some scooters having a restricted CDI? First of, I want to explain why CDI’s are restricted in the first place. I am getting a lot of people asking me, if their scooter has a restricted CDI, how to check if it is restricted and how to derestrict it.
