Paul,
Like most, I also used the handlebar
Ram Mount, it is ok. It positioned my
Garmin Zumo 550 just inside the screen on the clutch side.
The only problems I found was that I didn't like my GPS offset to one (left) side and my GPS screen is very difficult to see at an angle in direct sunlight.

MotoReva mount is excellent and I think the best mount for superbikes / sportsbikes.
The GPS vewing angle is not effected now by direct sunlight due to a far better position / angle.
Hope this helps.
RD.
P.S. I know
JeffST4RS also uses a
MotoReva mount and Jeff also thinks its great.
