I'm interested in this too. A couple of points, make sure any camera has image stabilization, a must have IMO. Gimbal mounts are affordable now and may also be mandatory. I don't have one yet but they might damp too much movement, ruining the whole moving vehicle concept. I haven't tried 'hard mounting' my video camera to the Talon yet, I've been very happy with the helmet mount footage so far. The problem with that is it's only one viewpoint, I want to include the front and rear suspension action occasionally.
This is footage with the camera mounted on the side of my helmet, over my right ear. It makes me feel like I'm right there. At 10:06 I learn that I have better framing with the visor up one notch. I'm using the original Virb which has been discontinued, too bad, I really like the camera.
Both helmet mounts, the top one for motorcycling is too high in the Talon and films too much roof. The side mount is what I used for the video.
