So...let's put it out there. I'm a girl, and I'm picking up my new 05 YZ450F on Friday. Well, I may be inheriting my husband's (thumpyz) 04YZ450F, so he can get the new bike with the new pipes and the Excel rims, and powder coating, etc...lol. I am one of those who came kicking and screaming off a 2-stroke CR250, but after racing in a desert race this weekend, and getting hands down smoked by a lesser rider in the washes (on a CRF450R) I am making the switch. So, what's the best piece of advice for a new 4-stroke rider, especially a YZ450F rider?
