Be very careful when getting a motorcycle mount. I had my HTC Apache (XV6700) in a locking clamp car mount that I retrofitted under the windscreen of my ZX-636, and that thing was solid. I installed it to the fairing stay where the mirror bolts on (I couldn't find any pics). Anyways, I was on the freeway overpass just riding (no wheelies), and I look down and my phone was gone. I was pretty upset, I even went back and walked the overpass to find nothing. Att he time I didn't have insurance, and the Titan (XV6800) just came out, so I got that. But just a heads up, I tested it, pulled a bit on the phone to see how locked in it was, but it still came out.
Here is a pic of a mount similar to the on I used. The on I had locked in place, and had a release button.
