heres the deal, im 16 and my parents wont allow me to buy a sportbike untill i move out and blah blah blah, you know the story. i respect that, but is there anything i can do before i get a bike so i wont be super rusty when i do buy one? i know of the msf and was planning on taking that, but would riding dirt bikes help any? i heard dirt and street are different is some ways but also the same in some ways. any help would be great.
