Well, im am going to be purchasing one within the next 2-3 weeks and need advice. i am really nervous about buying a 450 after coming off a yz125 and a quad, i know i can handle the power, ive ridden one and loved it, thats the reason im buying it, but i rode an 06 450, not an 08. i heard the motor is a little more mellow, it that good or bad? Also, what is the reccomended break-in procedure? what about oil changes/filter changes etc etc. sorry for all the questions, i just dont want to buy it and hate it and end up stuck with something i dont like. by the way, i am 5 foot 7 135lbs, most of which is muscle believe it or not, and i am still gaining weight. by the way, i am 14 almost 15.
