A1 or M?

Probably there is this topic already felt 1000 times but I (15) have the same problem as many others at my age: I have to decide between M and A1… Since my parents find a 125 because of insurance too expensive, they bought me a 50cc scooter, which my father had done from 45 to about 65 km/h. Now I would be interested to know if this tuning in case of a police control could be proved to me easily? Would it be only because of the tuning more meaningful A1 I would also like to make the motorcycle ticket A later when I have the money for it…. do you find it more useful to make M and later A or A1 and later A or what will be more cost-effective?
