I know this is an older thread but thanks for all the responses guys. I ended up trading my KLR for a dr650 a few months ago and think that I found a nice balance. I still wouldn't mind finding something smaller (dr350 or xt225) but compared to the klr, the dr "feels" much lighter and easier to work in the woods, plus I didn't give up anything on the road. Just to be clear, I don't ride a lot of single track and I'm not in a hurry to get anywhere offroad so that may be a factor for other riders. The dr is still a heavy beast to unstuck from a mud whole alone in the woods but it feels worlds better than the klr which probably has a lot to do with me being short.
Anyway, just thought I'd give an update in case anyone else is looking to downsize; don't overlook the dr650 if you still have to ride the superslab. It still seems like an xt225 or dr200 would be a good wife bike that I could "borrow" from time to time.
