Anyone mount a Drift HD on a modular helmet? Any interference with the flip up?
I have. BMW system 5 helmet.
I just got a Drift HD170 Stealth, which is a little larger in size than your HD I believe. I have a Schuberth C3 helmet and mounted the Drift on the right side down below the end of the face shield. I don't have any interference with this mounting. I looked at putting it on top of the helmet, but that was a no go due to interference with the face shield.
