I rode a dirtbike a few times before i got one of my own, but i knew after the first time that i rode that i loved it, it just depends on how you feel, but if your unsure if you like it or not, ride with your friends how ever many times you feel you need to, you will know if you want a bike of your own. And if you decide to get a bike, dont get a expensive one when you get your first, get something used, that way if you ride for a while and decide you dont like it as much as you thought, you didnt just loose a ton of money.
