I'm going to mount key chain camera to view the various parts of bike under loads like rear tire patch and drive train or fork action. For helmet I will get the cheap $40 ish box camera the view screen swings out to place in view to aim head at stuff, mounted to R side of helmet so can work controls by throttle hand. Helmet help steady and also magnify suspension impacts. The hi end cameras are at risk to smash and don't do anything better than the cheap ones unless for concert hall audio or HD resolution for cinema screen size blow ups. Audio is the bugga boo for all these. I'm going to try to wind muffler mine to let the engine get threw more.

There were examples of the key chain in Other Motorcycle section, they go screwing a bit on rough stuff and fast view changes but acceptable quality audio and video. I want someone with a air plane mounted key chain to try and chase me on Peel thru the twisties if it can keep up.
