I've got my fully decked out WR450 for sale. It's been a great bike, but it's too heavy to keep up with my friends in the desert (mainly Ocotillo Wells) who ride CRF450's and the new KX450F. I love the electric start on my WR450, speed and hill climbing ability, but do not enjoy it on the very technical rides (tight turns, etc). I'm thinking about the CRF450, KX450 and new YZ450F. I would really appreciate any insight on trade-offs for dessert (not track riding). I want a bike that rips, is reliable, easy to start and above all - fun to ride. Thanks!
