I hired a 2011 RC8R for a trackday at Snetterton recently and thought I'd share a few comments.
When I first pulled out of the pits I couldn't believe I was riding a twin, it was so smooth and the power delivery wasn't lumpy at all. I've honestly never felt more at home on a bike, even though I'm 6'3" it was comfortable and roomy. Despite the fact it was raining most of the day the RC gave me the confidence to push harder and harder with each lap. It didn't put a foot wrong and even when I messed things up (slight lockup of the back when I changed down a gear too many), it never felt out of control. It's probably not as quick as a Jap IL4 in a straight line, but it's got so much grunt out of the corners you'll be having too much fun to care.
My only gripe about it is the gearbox, I'm used to a slick and smooth Honda, but this was clunky and at times a little frustrating. It's probably just the case that I needed to get used to it, but I found myself wishing for a quickshifter.
In summary, stunning to look at, stunning to ride, bags of personality and it makes you feel special. What more do you want in a bike? I'm saving up already.
