These little GoPro HD cameras are amazing. This was shot by Hans while riding his trx450r. I don't have my own GoPro HD yet but I'm getting one. If your computer can run 1080p on youtube smoothly you're in for a treat (default is only 360p). This is completely raw footage. No post processing at all. Straight from the camera to youtube.
About half way through we do a few runs up Oldsmobile hill. You'll get a good view of my R and the 250R from Mr. Clean's "teaching the next generation" thread.
