This should be a lively debate.

The rider has some questionable techniques, but he also has what looks to be a bald front tire.

Please discuss.

As the front starts to tuck he chops throttle completely - that certainly didn't help.
 
Worn tire + what looked to be a cool, somewhat damp road = front end washout. He didn't touch the brake that I could see. Looked like he was a bit uncertain about his line, varying his lean angle as he went into the corner, and as he approached max lean the front end just gave up. Maybe have been saved with better lines and more hanging off, so that the bike wouldn't have required as much lean angle, but that's a fairly big maybe.
 
Definitely worn out tire + cool morning. Maybe a possible Black Ice?
 
The CA Forum is intended to be a first hand account of the crash in question.

This not to say that we should not, or cannot learn from this crash, but we are missing the critical component of comments from the actual rider. It's a good thread, but would be better put in General.

The first thing that caused this crash was the mental state of the rider. We can blame the road or the bike all we want, but the riders mental state was the first issue here. The rider took a sub-par motorcycle (tire) through a turn that is known for multiple crashes and fell. I honestly wonder if he was surprised, or blamed the motorcycle instead of his judgment.
 
I'm guessing excessive lean angle for given speed, poor steering/abrupt input.

Well, for whatever reason a bevy of riders crash that corner seemingly every day. Usually it's just past where this guy crashed (at the exit).
looks like this guy had a bad line, bad form and was forced to make a lean angle/trajectory adjustment that led to the low side (thanks to the aforementioned two "bads.")
 
seen so many vids of that corner eating bikes I'm starting to believe there is something on the pavement there
 
throttle choppy, rider movement choppy, damp road, worn front tire.

suspension (sag) probably off too?
 
Aside from the rider and the state of the tires or equipment, have a look at the turn at 1:52 and see what I see.

I've seen videos of riders stepping off this turn before. The video is usually shot from the same angle as the first half of this one. However, now that I see the reverse view of the turn, I now know why so many riders botch this turn at the same point on the exit, right at the end of the barrier.

Cheers!

+1... What is the story with this corner? I know a lot of the riders suck, but clearly there is a traction issue here somewhere. Right?
 
It seems like a lot of riders dump there, probably both due to showing off for the camera and the fact that we don't see the places people dump that don't have a camera watching (obvious eh?)

There seems to be several things: 1) the road has an increasing curve, 2) looks like a subtle dip in the road at that the crash spot and 3) there's dirt kicked onto the pavement from the dirt road that enters right where you see him crashing.

There's plenty of other threads discussing this aren't there?


Seems like a good place to hang out with a pick-up truck and a cellphone activated credit card swiper.
 
The rider (change that to operator) just doesn't know squat.

There is nothing worth mentioning wrong with the road. So what if a few Nobs crash? How many riders don't crash at that spot at that time on that road? The Harley rider managed OK.

The tire is not the problem, not at that speed on that road, with those corners.

The Operator may of hit the front brake, I can't see the operators fingers in that video.
But brake or no brake...the operator is at fault....100%


Any chance, that what isn't seen in the video is a CHP cruiser in the next turnout?

To me, it appears that the rider doesn't know the meaning of "counter-steering".

Looks like he is of the belief that you "turn the bars in the direction of the turn" because it seems that a split-second before he low-sides, there may be some negative camber in the road and he exacerbates tucking the front with steering into the turn. Counter-steer on neutral-gas, add gas & exit! :ride
 
Crashed because The Snake is evil.

The corner's treachery is over-represented by so many cameras is my guess.

I want to go there this summer and check the road's surface.

I don't even know what that means. :confused

This has been discussed a bit before, IIRC

Not sure what you see, but it looks to me as though there is a camber change there, and that the camber goes negative. That would explain a lot of the crashes we've seen in that riders experience a sudden change of lean angle compared to the road surface. Is that what you mean?

FWIW, his tire may have been a contributing factor, but I'm not sure a fresh tire would have saved him. The camera folk at that corner probably heard him coming because of that jerky throttle work, and thought, "We've got a live one here!" :party
 
Those lost the front wheel, crashes don't happen when Ya don't let the front wheel touch the road.
Wheelie for safety.
