tittle says it all. Go to 26:40 and look what happened:

what caused this?
I'm not sure where to put this post but I sure want to discuss what happened to this guy. In my opinion he was not going overly quick and still lost control, and I'd like to know why. Apparently the poster speaks spanish so I'll try to get in touch with him. From what I could find out, it happened between 2 small places called Putaendo and Cabildo, some 50 miles north of Santiago, in Chile.

Quick couple of looks, it seems like the rear tire lost traction? Maybe the front? There is a puff of smoke there around the tires, but I did not see the brake light come on though. And seemed like he clenched the handgrips, sticking the leg out didn't help, got the wobblies and didn't look where he wanted to go after he went off the pavement on the right.  I dunno, scary how a benign moment can turn bad real quick......

Perhaps something on the road, oil, sand...? He was hugging the centerline WAY more than I like to, almost on top of it. He lost traction and then it turned into a knee slapper. He's VERY lucky that there wasn't a car in the other lane when he crossed over.

What's impressive is how easy his friend picked up the downed C14 by nothing more than the handlebars. I'm sure he was pumped full of adrenalin.

I've seen this before either here or the other forum, if I recall correctly...in panic mode he gave it
more throttle because of his CrampBuster. Maybe I can find a link to the discussion.

Here it is: http://www.zggtr.org/index.php?topic=1967.msg23840#msg23840

it was road debris, not a bike problem. I did not pick up speed, just my friend slowed down as he saw me with problem.

Didn´t brake at all, because if you do the bike stands up and stops turning.

Anyway, I don´t remember anything from the accident...

I was going like 140 kms/h when lost the rear...

Just a broken left wrist.

   

It looks like a combination of things, it appears the road surface may have changed, maybe gravel or a tar snake right in his line, his body position wasnt great and he may have chopped the throttle, which would cause the suspension to settle even lower, causing hard parts to hit, robbing traction, slides rear tire even more, which resulted in a near high side.  Once all that happened I'm sure he totally tensed up, freaked out, and became part of the landscape.  I sure hope he's recovering.
His riding companion?  The bike first?  Really???

That's exactly what I thought.  He starts to walk over to his buddy, then turns back and goes for the bike.  Then stays away while working with the phone.   

F.Y.I. advance the video to 26:40 ish, to see the incident.

I've re-watched this several times and looking at the following bikes speedometer it doesn't appear that
he slowed down as much as the other bike seemed to accelerate. I think I could hear the connie accelerate when it
was in the dirt on the right side of the road. Since he says "I don't remember anything from the accident"
I think the combination of his panic and the Crampbuster made it worse. As for his friend I do believe he was
waved off to get the connie by the first responder perhaps at the urging of the downed biker.

I wish I was strong enough to just pick it up by the bars.

Another clip of the same, comment from rider is it was road debri. 

Like others have said, you can see what appears to be dust kick up from his rear tire.  Also notice he was hanging off in the curves.  I've said many times that I think that is the wrong thing to do on the street.  It makes it harder to make quick reactions to things that can come up on the street, and it puts your bike off balance.  Works for known conditions like a race track, but not so much for the unexpected on the street.

Couple thoughts...

Either debris on the road, or a tar snake got him.

The wobble was him losing the front, then regaining traction at the front, causing a violent wobble.

He had it saved on the right side of the road, got back on pavement, then went off the left side.  NO REASON TO CRASH once he had it saved.

NOTE - he went off the right, and his buddy damn near target fixated and went with him.

Not a good day at all.

Be safe.

yeah combo of a few things. body position was all outta whack for a sweeper like that. it was like he was trying to lean while sitting upright while his head was fighting to stay on the center line of the bike.  it does look like he lost traction maybe some dit or gravel.

...in panic mode he gave it more throttle because of his CrampBuster. [/url]

My Crampbuster has gotten me squirrely when I least expected it... It SURE gets the blood pumping.

I can't believe that lady was trying to steal his boots right after the crash!


Kidding.

Several things led to this result.
Looking at the road and surroundings there would be a pretty good chance of loose debris in the non swept areas such as the centre line and even mid lane areas.
The rear appeared to step out, the bike appeared not to slow down (cruise control?) he target fixated and froze.
The options he had were to heavily counter steer to correct his line once the slide was under control, my guess he has little or no experience of a bike moving around under him and it just freaked him out, this compounded by the cruise control meant he was a passenger pretty much as soon as it happened.

Hope the guy isn't too bashed up.

His riding companion?  The bike first?  Really???

Exactly- I was SHOCKED that he didn't IMMEDIATELY go to his friend first.  Who cares about the damn bike??!?!?!!  And then casually walking around, messing with the phone, it seemed "surreal".

Thank god he was OK.  Amazing to go through all that and just have a broken wrist.  Please let this be an example of not only good luck but PROPER RIDING GEAR.

As far as the throttle paddle (CrampBuster type), I have one, and I have been worried that it would get me into trouble too.  To adjust it so it helps with cruising, it is necessarily in the way of good brake/throttle control.  Hmm...

I am not gonna stand up for the BMW rider but I think he walked back to pick up the C14 since there were already five or six people talking to his buddy, I think he was just trying to clear the road as much as possible.  But that is definitely not what my priorities have been when I have been in that situation.  Both times I have helped a down buddy there was not a soul within 400 meters.

I think the guy hit some sort of dirt or sand in the middle of the road and he panicked. 

What's impressive is how easy his friend picked up the downed C14 by nothing more than the handlebars. I'm sure he was pumped full of adrenalin.

He picked that thing up like it was a 250 Ninja... 

Did anyone else notice he lost a bag before the bike went down?

Did anyone else notice he lost a bag before the bike went down?

Yes, I did notice that... if it was a bag, which I think it was.  The movement was pretty violent at that point, and if it was loaded, I could see that happening.  Although it is probably not supposed to.

When the roads turn twisty, "my" crampbuster comes off.
