I am thinking about buying a friend's dual-sported 2000 XR650R. It has 4000 miles on a rebuilt engine and many extras, such as late model CR450R inverted forks and triple clamp and three different tanks (Clarke, IMS, stock) of different sizes. I know he takes great care of it. What's a good price for one of these? I know its a heavy bike but how are they in tight singletrack? Also, how does this year compare with later models?
