You know my 750 has a set of what I guess are slight rise drag bars and dare I say that those flat bars inspire just as much cofidance, if not more, than the clubmans.
On the old British bikes from whence the Clubmans came, the seat was lower relative to the bar. When your hip pivot is higher than where you grip the bar, like a CB750 with clubmans, its going to take some getting used to, if ever. Its just human ergonomics. a flat bar is just about right, or slightly higher with a down bend, is much more natural, for a CB750. Ideally at lewast to me and others who have studied it, the easiest steering inputs will occur the more your shoulder is pushing your hand. If your shoulder is too high relative to your hand, you'll feel discomfort.
With all the hub bub about custom oil tanks, and with this new welder guy I'm working with, (nothing phases him) I'm thinking about dropping the seat height on a CB750 by cutting the rails and dropping them. That would feel like my old Bonnie.
