This bike was on my list when I ended up buying the Busa. Unfortunately, it was brand new, expensive, and no used ones in my price range. It looks like a he11 of a bike in my opinion. Not as high performance as a Busa, but probably more comfortable and it has storage space.
Smaller injectors, has a wild variable cam timing setup, I believe less compression. More weight and the hp loss of using shaft drive. I road one last year, swapped rides for about 25 miles. Impressive compared to a FJ or ST1300 but it is not Busa or ZX 14 material in the performance department.
I have an 08 Connie and an 09 Busa. The previous writer that said the Connie was impressive when compared to the ST and FJR (I had an ST and still have an 05 FJR) hit the nail on the head. The Connie has more power, is more comfortable (to me), and is more economical because it has a six speed. The heat management on the Connie is vastly better and the lay-out of the bike (riding position and instruments) is much better. On the other hand, there is as much more power in the Busa, compared to the Connie, as there was comparing the Connie to the FJR.
When I get older(alot older,lol) I'll probably be debating either the concours or fj. I've never riden either but I've sat on both at the dealership and I have to say either seems VERY comfortable without having to get a monster like a goldwing...
