I'm fairly sure it was because there was a dip in the pavement, and the forks, at an angle, weren't able to follow it fast enough to keep traction.
You can see the rear of the subframe lift as the bike tilts forward in reaction to the front end dipping.
Probably with better / hotter tyres and better surface, only her boot slider would have touched. But better suspension, or less lean angle so the suspension has a more direct vector on mediating the weight shifts, would have been even more successful.

Binned it every bit as well as a man would have.
Yes, road surface and all that, but really the same answer as every other muppet that spreads their bike down that road: obsessed with doing a hero lean to impress the audience, forgot that physics doesn't care how many cameras are on it. ____________________ Biking is 1/20th as dangerous as horse riding.

It shows one of the biggest failures with motorcycle cornering technique... you lean to get the bike round the corner quickly, not because leaning the bike looks cool...
She was moving her body the opposite way to the bike, she had the bike over far more than was necessary and had random throttle. Every time I see vids of that corner I'm surprised by how low people are going for a complete lack of speed, show-off rather than functional riding... ____________________ current: ducati monster 750

I suspect it was 'recoverable' at this point.
She has pretty decent arm position, but I wonder if they were a bit too rigid. Or possibly she tried to 'correct' the initial loss of traction forcing the bike down.
You can see after the tyre seems to slide out a bit, the steering is turned inwards, but the bike doesn't really come around.
I suspect the 'lack of adhesion' moment was the patched tarmac.
A bike with decent tyres should be able to handle what we say there, I'd say.
I suspect she had tyres that didn't work well from cold and maybe had the right side cold if she'd been going easy up until the corner with the camera.
I suspect hanging off would have helped - if nothing else, it adds a little 'flex' to the system.
I also suspect a slight positive throttle would have helped - they generally recommend you are gently accelerating around a corner to put a bit more weight on to the rear tyre.
If she was on a decelerating throttle position, it would be putting a lot of load on the thinner front tyre.
To be fair, I haven't saved a great deal of front end slides (rear slides are much easier to handle). When I was racing well I was able to catch a few mid-corner front end slides while still on the brakes. Others I didn't catch and ended up getting a lift back (or in one case, trying to re-enter the race, then realising I didn't have a right hand foot peg!)

Then she'd have turned tighter.
The only way (that I can think of) to force a bike down while holding the same cornering is to push your body the other way. |
All of this ^^^ Speshally the patchy tarmac. The back end stepped out almost exactly where it met the darker surface.
It looks like Looser's Hill (Mulholland Hwy CA) where all the 'Grates' are to be found.
Some other Murican fcukwit in a Port-cha or High-a-Boosa possibly binned it in some sort of fireball previously which destroys the road surface.
On off throttle upset CoG loading-unloading tyre footprints.
Everything she did was wrong but It in no way suggests I would not 'hit' her.  ____________________ W-ireless A-rtificial L-ifeform L-imited to O-bservation P-eacekeeping and E-fficient R-epair |

I reckon she should have been WAY nearer the middle of the road throughout and watching the vanishing point instead of the white line until she could see her exit. ____________________ “Rule one: Always stick around for one more drink.

But it does; the whole Shrodiners Cat thing, of whether any physical observation is merely observed because some-one was there to observe it...
We then have the Denis Nordon principle, if something can go wrong it probably will, more so if there's a camera watching.
To which the GP Paddock provided lots of supporting data, in the early days of 'on-board' cameras, which almost inevitably increased the chances that the camera car / bike would crash, break-down or otherwise fail to perform.
While You-Tube itself, supports the suggestion... there's gazzillions of video clips of people falling over, crashing cars, falling off motorbikes and other wise having calamities when there is a camera about!
Yet walk down the road, people are hapily going about thier lives, unobserved and quite calamity free!
So the answer to why she fell off.... Some-one pointed a CAMERA at her!
You see, a camera observes, there fore it makes light behave as particles, so that the cameras CCD or similar sensor mechanism can 'count particles' striking whatever points of the receptor.
Light would PREFER and if unobserved to be a wave; so in order to become a particle, to satisfy the observing camera's apatite for photons.. there has to be a change in state.
Any change in state, as we all know from Einstein, is associated with a change in elergy levels, Energy = Mass times the speed of light squared; as a wave, light has no mass, it is pure energy, but to become a particle, it has to transfrom itself into matter, which has mass... mass has gravity, so at the moment light changes state from wave to particle, in order to satisfy the camera, a new 'gravity' comes into existance... THIS influences all matter around it,
THIS causes a chain reaction, that results in a micro-fluctuation of gravitational field; a 'gravity surge'... and THAT is what makes people fall over in front of cameras.
See... simple physics. It WAS the camera! ____________________ My Webby'Tef's-tQ, loads of stuff about my bikes, my Land-Rovers, and the stuff I do with them!
