I had by '11 CB1000R for four years before selling it for the F. It's pretty hard to fault, well built, smooth power delivery, nice handling characteristics. 2008 - 2012 it was up there with the rest, but for me Honda has failed to develop the bike into what it should be now. No TC, no gear indicator on it's digital dash and underpowered in it's class.
Oh, and I knew of only a handful of owners that kept the exhaust.... not only is it a little ugly and very heavy, it's whisper quiet!
