im picking up my first 450 in about a week. im coming off of a 2002 yz250f, which was worn out and i was just wondering if im gonna be able to handle the power of a 450. im 15 135lbs and been on a bike for 8 or 9 years now. i have a tendancy to twist my wrist a lot being on my 250f but ive been told that on these modern 450 mx bikes you have to know where to stop your wrist. is this true? or can i pinn it coming out of a turn like my 250f? also, where can i get a kick ass graphics kit for a white 2008 yz450f? thanks.
