Home made GoPro motorcycle mount

I'm pretty excited about this. After a week or so of trying ideas out, I've come up with a pretty solid mount for the GoPro. A 3/4 dowel goes into the axle hole with some PVC pipe mounted to that. It can be rotated to film either frontwards or backwards. I've made dowels that fit both my Honda Interceptor VFR800 and my friend's Harley Davidson Heritage Softail. I'm renting a Heritage Softail for the big bike trip so it should work just right.
