125er throttle – at maximum speed kapp over 80 kmh

Hello have not found anything suitable here. Therefore my question: I have a 125 scooter, which is not throttled and is to be driven by a 16 year old with the corresponding Füherschein. Here is a limit of 80 kmh. However, it has a top speed of 84 kmh according to the manufacturer anyway. If scooters are throttled, usually also a certain tolerance in the speed is eliminated. My question: Does the scooter actually still have to be throttled or is enough if it is If that’s enough, is there still a confirmation that the 16-year-old can drive with it? Thank you for your help already.
