There's a video going around on the internet with a motorcyclist coming out of a corner and just letting go of the bike - ghost riding. The bike continues on and wobbles while the rider gets back up and runs and catches the bike. You can find the video (since there's a restriction for posting URL's without meeting a prerequisite) by typing "Biker Loses Bike Then Recovers Amazingly" and either break.com or metacafe will suffice for your viewing pleasure. Theres no question that the video is staged. It's believe to be an ad for whatever this "Notorious" is shown at the end of the video. Best I found on that was a bike club called "Notorious," so there is correlation... However, beyond that theres much debate whether this is a real stunt or even possible in the physical realm that we occupy. So I present this case before you to confirm or debunk this stunt... My theory: I believe this to be a stunt and an actual real event. My reasoning is because the twin gyroscopes spinning on the bike and its natural resistance to angular change - hence the bike's natural position to being upright. To add to it, from my own personal experience riding sport bikes and my understanding of them, the bike will not lean unless you countersteer the front wheel. Which causes an adverse change on the gyroscopes alignment causing the bike to fall over. The wobbling you see after he loses it is the gyroscopes resistance to falling over. Now I am aware of a threshold revolution speed that the gyroscopes must obtain to counteract any force trying to disrupt their natural course of being upright. I personally contribute the lower revolution speed to being sufficient in keeping the bike upright to the rider's mass not being on the bike... Anyways, thats my take on it. Hopefully someone that's smarter than me can confirm or debunk this.
