Pretty amazing. Bike steps out, catches, throws the rider, keeps going straight without a rider until losing speed and gently tipping over. Rider and bike nearly unhurt.

Here's the video

The camera didn't follow the bike after the fall, but here's the thread, with a longer description:

It's called a high side crash. What happens is the rear tire loses traction for an instant and when the scared rider releases the throttle the tire grips and tosses the rider.

 

Happended to me once in front of my house going about 20 mph on cold tires, before I knew what was happening I was already airborne.
