I want a 450, but it is a lot of bike, what do you weigh and how much seat time have you had. Love my Honda, want a 2013 CRF450R, but it is still more bike than I need, or could handle. I am an old fart, I am 44 now and it clears doubles cleanly with ease, a 450 would probably get me in trouble. Just get it sprung for your weight, I weigh 230 and it still rips.
