I'm seriously considering picking up a BARELY used '08 WR450 that still has the throttle stop on the carb and maybe... maybe 2 hours of riding. Probably more like an hour or less actually in motion. It looks like it's still in the showroom, no boot marks on the frame/covers, titties still on the tires, airbox is clean as a whistle. They are asking $4800... sound like a good deal? Book value is about $4600 but doesn't factor in the NEW condition. I'd like to talk 'em down to $4500 or less, but not sure they'll go for it. Opinions please... Thanks!!!
