I decided that my back was well enough for a ride down the interstate, to see how it handled. I was actually pretty impressed. Though I did not take it quite to 70 for a few minutes, I didn't find the buffeting bad at all. Of course, i was not pulled in the wake of an 18 wheeler, but I thought over all it was solid. I have changed the rake some from dropping it, so that might have helped, but squirrely is not an adjective I would give it.
Needless to say, the bike got some looks. I got off after a few miles and looped back home on a different road. My back isn't up to the beating yet.
Unlike the S40, which is a fast bike, the RE has more pull in the lower end of the revs.
