No splintering around the breaks so with the shiny looking surfaces I assume it's a cast wheel.
A friend had a wheel shear off his Mitsubishi Evo after having them powder coated and the company not really knowing what they were doing, overheating them to burn off any grease or not letting them cool slowly, either way it made the alloy brittle and this happened when he braked at about 80... There were cracks in the spokes of the other three as well, so one set of OZ wheels written off and a very nasty accident avoided by luck more than anything.
I’m guessing that’s one of their track hire fleet?
Looks like it’s either suffered the same ill treatment as Stonesie’s mate’s wheel, or at some point it’s had one too many wheelies. Either way that’s a scary thing to happen when you hit the anchors! Any idea which track Duke?
Iirc didn’t Robert Dunlop encounter something like this at the TT? Resulted in a court battle with Honda that he won from what I recall.

You might be right - didnt a similar issue kill R Dunlop in the end? Was it his rear wheel. I'm recalling from memory so i could be completely wrong
Google tells me that R. Dunlop's engine seized at @ 160mph & he grabbed a handful of front brake instead of the clutch, throwing him over the bars, only to be hit by another rider.
All in front of his son, young Michael Dunlop, I can remember the pics of him winning a race that meeting in memory of his Dad..... I was in bits reading the article.
Robert had a rear wheel collapse at the TT but that wasn't the accident that killed him, that was the one that should have killed him and meant he could only ever ride the smaller bikes afterwards because hes right arm was so badly damaged, and then the engine seized at the NW200
Remember: If in Doubt use Full Throttle, It may not make the situation any better, But it will end the suspense...
How did this happen??.
Im struggling to understand how the braking mechanism would do this. Im thinking there was fatigue in the wheel, can this be contributed to the incorrect tyre changing machine being at a higher pressure.
Does not install confidence on realiabity of wheel design, or wheel change.

Fwiw I presumed that the thread title was just a bit of black humour mate?
It seems more likely that the rim actually detached as the result of an impact of some sort, perhaps something getting between the forks and the spokes.??
You'd think there'd have to be some sort of impact involved wouldn't you?? Otherwise it would mean that the traction of the tyre was stronger than the wheel itself, which doesn't seem likely.
I'd bet on a lot of braking to avoid a kerb or something...which he hit anyway
