since the rear squats during acceleration, then that bracket looks like it would be under tension.

I am trying to get an idea of where in the rear suspension that bracket attaches.. the dogbone on the bottom is running forward, right? What was bolted to the top where the holes pulled thru?

I would also like to see the bottom on the rear fender.. if it broke and hit the tire at 60+, there should be some significant burn marks from the tire.

Plus, the rider admits he doesn't exactly remember what happened, and we have an eyewitness from behind with the story..

Ever seen a high-side in person? I know when I'd put my money given those choices...

i've seen the bike and the bike didn't flip... at least if it did, it left the whole left side unscratched, even the tail section.

Not only seen, been party to a few. Not the best way to get off the bike, altho one of the quickest...

On the Triumph thread someone said he helped adjust the chain the day before the ride, and noticed nothing odd in the suspension linkage; that tends to rule out loose or worn.

It would have to be very weak to break under the loads for the speeds he was going, unless there was a huge bump mid corner... even then hard to swallow.

from the tags, the bike looked like it was only 4-5 months old so hopefully it wasn't worn out yet.

While I don't believe the story of the rear link breaking before the accident, the link did break under compression of the rear not lack of it. You have to understand how it is all tied together on the rear. The shear forces when the rear is compressed would be in the direction of the breakage. I wish I could do some animation showing you guys the way the suspension works and where the tension would be under load.

You can look at the pictures and tell it hit the tail section and sheered the mount in the same direction. Who are you trying to kid?

I haven't laughed this much in a while.

FYI, I'm not laughing at your crash, ix09.
Glad you made out okay.

Absolutely. The swingarm is pulling up, trying to yank the bolt out of the eye of the bracket that tore. The bottom hole pivots on the dogbone. A real hard shot that the shock couldn't absorb would pull it apart.
