Breaking wind

[flynrider]

A frame-mounted fairing is so much safer and stable. A large handlebar mounted fairing gets easily deflected by wind at high-speed (anything over 60 mph from my experiance) causing a twitchy feeling that is not desirable at all.
Not many aftermarket frame-mounted fairings available.
Anybody know the exact width of a CB1100 tank at its widest point?

For what it's worth, I've got a handlebar mounted Deflector DX on my CB11 and it was rock solid right up to 112 mph. The larger Plexi 3 on the CB750 has seen 110 mph. Not sure about other brands, but Nat. Cycle fairings mount solidly and are pretty stable aerodynamically. Cross-winds notwithstanding. But that's a problem with most types of fairings.
