Toytuff has a nice CBX refresh going on what started as a nice example of the late faired CBX ('82). I would not mind having one like that if I could afford it. The CB1100, yeah I would even consider it, but it is less affordable than a nice CBX. The CBX would probably be a faster bike hands down.
But you better be mechanically adept to maintain the six cylinder beast...or, have deep pockets ($) and be good friends with a skilled mechanic who can do the work for you if you aren't able.
(Edit corrected CB900 references to CBX...)
