I am looking at a WR450 that is in pretty good shape all around. The plastics are about all that shows age. It is a 2004 and it is titled...no plates, just a title. I am curious what is a fair price for one of these beasts. Also my intention is to use it on trails exclusively, and some of these trails are extremely boulder infested, so lots of step ups and downs. Will this be just too much bike for this use? I am 6'2 and 200# if that means anything to bike size.
