I rode a Lightning during a demo at a Park City, Utah bike show years ago. They took us on a 20 mile loop. I stayed in the back so I could lag behind a little to gain a little room for seeing what it would do. It wasn't clunky at all. I was impressed with it. The only issue I had initially was that I kept bumping into the rev limiter. I had ridden there on the CBR which has a redline at ten five, so I had to acclimate a little and short shift the Buell. Took about a mile to adapt. The bike was a hoot.
