It looks like there are pictures missing. Looks to be a couple of frames per second right up until picture 18. Then picture 19 the guy is already flipped over the car and headed toward the ground.
Thinking he was going a bit too fast for the corner too. I did notice he didn't pull the newby move and brake in a lean. He was upright before he applied the brakes so I can't tell if he's a total newby or not. The brakes do go off/on when he's upright though so he didn't keep them applied throughout and I'm not really seeing any kind of dive on the bike so I'm thinking he didn't apply the front nearly as hard as he should have either. Waving to the camera and pulling the shit he did sure puts him that category though. Both hands on in a corner.
It almost looks like he tried to turn too hard and bounced it up off the peg/frame and that threw him back the other way...
I agree there are some frames missing
Why anybody still runs the Tail is beyond me. There are many other less crowded roads in the area. The last time I did it was in '09 and it was already like a parade even during the week.
