Helmet mount works best for steady shots but I rarely wear a helmet. The 3M tape works just fine.
I've run it on the side of the front fender, the bags, and pretty much anything with a flat surface using the suction cup.
Most often I run it on the fairing, I put a 3M mount on top of the inner fairing on top of where the radio is. The camera will see over the short windshield but doesn't work with my cee baileys. I've run it here at the drag strip and just bombing around town, you can run it backwards and see yourself driving too if you're not ugly.
My inner fairing isn't painted yet, if it was I don't think I would mount the camera there.
