i've done some on board video, and sound is always a problem. the only solution is to cut the audio gain way down and wrap the mic is a wind noise deadening material.... or strip the audio out and dub in some MP3 that you like (which is the most common thing to do anyway).
I have the
Sportbike Cam mount and it works quite well, but being that the tank is plastic, its not quite as rigid as it could be. My video quality suffered a bit, but most of that was due to the camera itself not being well secured to the mount, and my suspension being a bit harsh.
check it out if you want. Its coded in DivX and you can hear the wind noise which i didn't bother ripping or dubbing over.
Rte 2 in MA its about 20MB.. dial-up beware..
