Ouch! Looks like he might have throttled up too much exiting and still at a good lean? Watched it a few times and front end almost seems like it picked up just before he went down? Only the rider knows!!!
And here is your order...
Same mistake in all turns before that crash: Missing apex a bit, full lean angle and opening throttle and does not pick up the bike at all. So a typical error with driving line; turning in a bit too early. And then when rider is trying to be faster just by using throttle the result is obvious, if DTC does not save the rider.
Maybe DTC was off because if the bike has stock ecu; it makes the bike feel very very sluggish out of apex if rider rides like that (wrong line and twisting throttle grip).
Or ecu had RCK and DTC setting were made for a fast rider who does not want to use DTC as a safety net.
Or stock ecu DTC was tuned down/ is it even possible to tune 2019 stock DTC so far down that it allows rider to make a low- or hi-sider? Tyres changed/ tyre radiuses also involved?
I was watching the speedo and listening to the throttle right before the spill, looks like as others have stated, too much throttle too soon possibly? Just my opinion. Only the rider knows what really happened, just making an opinion from an observation.
From what little I could tell (240p? Seriously?), the rider was dialing in some serious lean angle (big balls + borrowed bike) and being very liberal with the throttle on exit. Probably relying on DTC too much, OR probably had DTC turned off, which is weird that BMW would allow in a demo ride. Another journalist's video on the same track (same demo day?) showed him manually blipping the throttle and making shifts with the clutch. When questioned, he said that the quick shifter was inoperative in that bike. Maybe it's the same bike that had some sort of system failure. Again, weird that BMW wouldn't have taken it out of the rotation. Let's hope BMW didn't hire out traction control to Boeing engineers for this model.
Anyway, this shows very well how much we've come to rely on TC to be able to ride 200hp super bikes like 600s.
Maybe it's just me, but it looked like this was just waiting to happen after watching the rider gas it out of the first turn at full lean. I know it's been said before, but this looked so avoidable using traditional technique. I'm guessing it's possible to catch a marble just before a trigger limit and DTC can't recover a front slide from it, but I don't really know. Hope the rider is doing okay.
