Hi Andre,
Got it. To recap briefly, you ran wide, and looks like you rode it off the tires. The bike went down before it went off the track.
There is a lot of technique that goes into riding well, and we won't be able to cover the whole gamut here. Many on this forum have read Keith's 3rd book, Twist of the Wrist 2. Have you by chance? Having a look at Chapter 23, the Two Step, might shed some light on what happned (pg 98).
There are other things that could be the major contributing factor, but without talking with you, can't just give a blanket statement/critique, and really have it be accurate.
Best,
CF
Thanks for looking at the video. And suggesting the reading. I will pull that book out of my closet.
