The clip looks relatively intact. I would surmise that if you could somehow assemble the shock with it halfway installed, pressurize it to 165psi and it doesn't blow up in practice or the heat, it would shear the clip and it wouldn't be complete. 

I'm thinking their are other pieces like the casting on the bottom of the shock that may have failed to enable that spectacular picture. Those clips are small but used worldwide in billions of high pressure applications.

Only since 1985, but I'm sure you have much more extensive experience.  Do tell.

Didn't Shane have a shock failure as well, maybe last year?

Anyway, Item 12 ⬇️

That what the shock looked like after he landed that triple.

I don't want in the middle of you guys emotionally, but the circlip looks a little deformed. It's possible the casting let go or "body"? Others have commented on the possibility of overfilling.

I’d love to see a pic of the shock body. It Could have cracked causing the clip to blow out. 

According to Kenny it was gone.

Around the 7 second mark you can see it fly out

If the clip that retains the seal head came out like shown, you would think all the guts would come out and the rear wheel would over extend beyond normal, but we didn't see that. Very strange regardless!

Anyway, Item 12 ⬇️

Based on the size I’m going with #11

Unlikely it was #11, the spring still worked.

More likely the reservoir split, the end cap (#15), the bladder (#15), the c-clip #12, the nitrogen and shock oil, exited the shock.

But the crash photos show the reservoir intact...

Man....that looks so much worst than in the broadcast...and the broadcast was bad enough.   That violent explosion of energy at the end.    Shocked

Not sure what year maybe 94-95? Craig Decker on a Suzuki SX race, shock broke (shaft?) ended his career could have been much worse, although he broke his back he is fine today.

Ken described the shock body being grenaded. Clip looks too big to be reservoir.

8 down votes and zero up votes. That's why they are vitards.

Put my sleuth hat on. I'm going with the actual shock body had a failure because the reservoir looks in tact in this zoom in. Also look at where that smoke is still coming from lower below the number plate.

You don't need to be a sleuth. KRoc said the end of the shock body was gone. Not sure why this is so hard.

The smoke is from the oil on the hot exhaust, the oil may be coming from the reservoir or the shock body if the shock body split, until there are more photos it's all speculation.

The c-clip is the photo has a large gap between the end, when compressed it would be small enough to be #12 or #9...

The reservoir looks intact in that photo I posted.

As it does in the same photo I posted before yours!

That doesn't mean the bottom or inside of the reservoir hasn't fractured.

Hopefully somebody posts a photo of the damaged shock.

Yeah kind of consistent with the same failure as Shane had.

I set up a quality department for in house damper manufacture, and am involved in doing another one.

You probably got 8 downvotes cause you are constantly on here acting like the smartest guy in the room and calling everyone else "Vitards" yet you consistently post completely ignorant shit that you are NEVER man enough to back up.

So Lon....shut the fuck up, you are just as much a Vitard as anyone.

my theory is that when Kenny's shock failed, it sent the circlip spinning into low earth orbit. When it returned, much like a boomerang, it hit Sexton's throttle body, cracking it and causing his throttle to stick.

Haven't seen anyone address that yet. (or I missed it).      Seeing it live was gnarly on the broadcast, but that front view really highlights how explosive that push was.

Pretty wild, whatever it was sure seemed to speed up the endo.

It’s not circlip part number 9. 
 

if this circlip had failed the shock shaft would pull out making the suspension hyper-extend. 
The video this screenshot was taken from shows the shock not extending further than its ‘normal’ range of travel.

The last bit was the nitrogen bladder rupturing, resulting in a fine-mist of shock oil spray. Once that hits the exhaust components it smokes.
