I found my 6R to be quite powerful and quick when I rode it. On a trip this weekend on my FZ1, though, I was riding with a buddy with a GSX650F. Very similar performing bike to a 6R. His main complaint was passing power. When I was in the lead and pulled out to pass, he said he was flogging his bike behind me and I was still leaving him like he was standing still. Probably a bit of an exaggeration, but he did spend a bit of time this weekend lamenting that, although he would probably never use the extra top speed, he was interested in a more powerful bike for the passing power. I have to agree with him; when I click down to 2nd gear at 50mph so I can get by a camper trailer or something on a short straight, I like to get out, get by, and get in, no wasting time. I find it a lot easier to get around slower traffic now that I've upgraded.
