Need urgent help……………………..

So I made my car driver’s license a short time ago and got a scooter Aprilia sr 50 www Year of construction 2000. Now the scooter drives according to Tacho 70, but would say that it is far from 70 and it does not get beyond 60. May I drive my scooter so further or do I have to throttle it? What legal consequences do I have to reckon with since I am still in the probation period. Thanks in advance
