Ok,so my dad doesn't like motorcycles but i dont know why,anyway i want to get a 49 cc Speedfight 1 from my uncle and my dad doesn't let me,and when i ask him why he just says that he doesnt like motorcycles,

,and whenever i say something about a motorcycle the same thing,so does anybody know some good arguments cuz for gods sake it is a scooter not a hayabusa or a chopper,and i told him that a lot of times but he wont listen,i always say that even if i want to go fast i cant becuz it cant go fast and plus the squt is from my uncle so if we buy it,it will cost allot cheaper than a new one,plus a free helmet and a jacket,so i dont "procreating" know how to convince him,can anyone help please?
