I no longer have my CBR.
I just don't have the time for bikes anymore - if I had one it would sit in the garage unused week after week, month after month - so there's no point owning one.
But I used to have a CBR600FS that, in the days BC (Before Children), was second in my affections only to my now wife.
That bike taught me how to ride fast AND safe. It showed me how much fun you could have by yourself(!!!!!). It took me to places that I would never have seen if I had not had it.

I'm not sure that I would have another one, even if I had time for it - I think I've outgrown sportsbikes anyway. Maybe something like a V-Raptor or a Monster would be more fitting.
But I'll never regret buying that bike, and I'll never forget the fun I had with it and the places I went on it, nor the company I kept at the time.

If you are under 40 and want a bike that'll do virtually everything and do it well, you won't go wrong with a CBR6. Which model you ask? Any of 'em'll do!
