Don't get me wrong, I think the KLX and WRR are fabulous bike for back roads, commuting, etc...but they are no where near as good as a 650 for gobbling up miles on the slab.
Umm...aren't you at a bit of altitude, in a hilly part of the country?
It also depends on WHICH bikes you're comparing. I wouldn't want to ride an oil-burning KLR or a paint-shaker 640 on a long slab trip either. A WRR on relatively-flat ground at low altitude might be perfectly fine slabbing-wise for many people.
