I've been thinking about rigging up something to video some of my rides too. I've read a few places that the handlebars are not the best mounting place because they get all the feedback from the road causing the video to be shaky. Yours didn't seem to be very shaky at all. Were the roads really smooth?
I was thinking about mounting something to the engine guard, but it's so close to the bike that the front wheel would be in the way. Will that Ram mount hook to the engine guard? If so, will that arm get it away from the bike far enough to get the front wheel out of the picture?
What kind of camera did you use? I've also seen a couple places that the vibrations of the bike can mess up cameras with moving parts. I have one that records to a hard drive, but also has capability to record to SD cards, which is probably what I'd do. Did you have anything to protect the lens of the camera from bugs and road debris?
Now that I've given you the final exam for Motorcycle Video 101, the video looked great and I agree with EQ stay away from 18 wheelers on 1 lane roads.
Mom, I'm not wearing my helmet only for the purpose of taking this picture and
the background was digitally blurred to make it look like I'm going really fast.
