I rode my buddys 03' yz450 today and I wasn't impressed It is completly stock with only about 10-15 hours on it. for where I ride i barely got into second gear. On my 250 i can get into 4th about 1/4 throttle. It felt very top heavy compared to my 03 250f. I don't know if I just wasn't used to it or I just don't like it. BTW i'm only 5'6 and 130lbs. without gear. he is about 5'3 or 5'4 and maybe 120. I'm much faster on my bike than his and I'm faster than he is. I just don't get it.
