That's some excellent evidence. If you need to ride mixed roads, keep the KLR. If your riding is mostly on pavement, the Burg will treat you well. We all need to adapt the ride to the road. In this case, the Burg may be a good match.
I never felt like a sissy on a scooter. I still have great admiration for the SYM HD200. If I rode that machine correctly, I could leave most of the pack in the dust. It had 175 cc's. It returned 72 mpg. If a scooter is something you're comfortable with, be comfortable on a scooter. They are outstanding machines.
