Just to pile on, I recently bought the XT but I'm 6'2" and 230# ready to ride. I've put on bar risers +1", a 5.8 rear spring, IMS 2.9 gal tank, Seat Concepts IMS seat (wow what a difference), Knight Designs 7/8" lower footpegs. I've been riding big 4-strokes since the early 70's and still have a number of them in the garage. The XT is an amazing bike for the slower technical trails --- abundant controllable torque right from the bottom. I rarely get into the "pipe" such as it is. In my opinion, it's not the bike for riding any distance on a highway or long stretches of straight dirt roads. If I want to rip or have any distance to ride on roads, I'll ride my Husaberg FE450. Otherwise, the XT is lighter, easier to reach the ground if you need to, very good in the tight stuff, and has great motor.
Not sure where you are in Idaho, but I'm up around McCall for 6 - 8 weeks in the summer and fall.
