Theres a few models....I personally like the CBX750F...these are the DOHC models.
There is also a shaft-drive CBX750 (police version, but maybe other models?)

Edit: Rereading the thread.....I think the CB750X referred to by the OP was that originally posted-the "Bitza/hybrid"...apologies to the OP if I misinterpreted, and we have digressed. No thread hijack intended.
