you are going to hate my answer, but i have to say it, get a 600 or under. i dont care how many dirt bikes/atv's you road as a kid, i dont care what your friends have, i dont care how quick you want to get to 150mph. be smart enough to understand that you don't have to have the biggest baddest thing in town. we are talking about your life, and the life of people around you, family/friends included. there are mistakes you can't make on a liter bike that you can make on a 600. imo find a honda f3 600 that has fallen over a couple of times, that way you dont feel bad when you drop it in your driveway. they are quick, they turn more than you will ever lean, and they look ok. buy it right, ride it for a season or two, flip it for what you paid, then find something else.
