Has anyone snapped a peg hanger by standing on it?

Hi Graham, thanks for your observations, is this something you understand? As stated I'm not after screwing Kawasaki but moreso interested in finding out the root causes analysis.
Allegedly...! If Kawasaki don't want to have a look, or they send them back afterwards, then feel free to send them to me to have a look. 
Yes completely misread the rear set question 
5am starts don't agree with me 
The casting looks almost webbed for strength but I wondered if the webs might be a design feature to allow the bracket to break as a sacrificial part? I'm just trying to justify to myself the design concept, either way my brain is fried now.
Must get some

I wouldn't go so far as to call them crumple zones, but multiple areas (such as those that commonly attach fairings) are made from cast aluminium.
Including parts of the frame, engine cases, barrels and head. Die casting allows lightweight and intricately detailed parts to be made relatively cheaply, not because it makes them brittle.Mr2Mike said:

Die casting allows lightweight and intricately detailed parts to be made relatively cheaply, not because it makes them brittle.If you have a fairing go and have a good look at how it's attached to the bike. You'll see a long bolt made from this monkey metal. It will even have a hex attachment so you can remove after it's split.
Also go and have at peg hangers. They're all made the same way regardless of premium manufacturers. You'll also notice they're only attached at one end. It's not just aesthetics. This is so it "snaps". (I speak in generalisations, I'm sure there are exceptions).
I acknowledge the lower production cost earlier in the thread. The fact they protect your frame may have originally been a welcome side effect, but now it continues.
Since I'm reminding of what I said I would also like to point out I still don't dispute this could be a problem with the casting in this instance. It's just not as likely as excessive force.

I'm sorry, I can't bite my tongue any longer.
The suggestions that the footpeg hangers are "designed" to break like this (in a crumple-zone manner) are simply laughable
Edit: for another
To be fair he said it was found to be a (happy) bi-product of the manufacturing method. I know that if I dropped my bike I'd much rather the footrest hanger snapped than it twisting the boss it was fitted to. Obviously that shouldn't mean they'll break of their own accord, but the Prof did say he'd expect it may have had a drop on that hanger before. I can't see the pic's, but that sounds feasible to me!The suggestions that the footpeg hangers are "designed" to break like this (in a crumple-zone manner) are simply laughable

I know that on certain cars 'weak points' are engineered in to avoid bigger problems.

I have never stood on the pegs for exactly that reason. I just don't have much faith in thin bits of cast aluminium holding my 20st weight.
As for Kawasaki, I wouldn't surprised if they came back with "that's why they are called foot rests and not body supporters".
20 stone, you are almost like 2 of me.......As for Kawasaki, I wouldn't surprised if they came back with "that's why they are called foot rests and not body supporters".
As an update, I am having the broken peice repaired, Arrow no longer make rearsets and carry no spares at all, so if you have a failure then it's complete new rearset time or you will have to sort a repair yourselfe.
Here is an extract from the importers email,
"as mentioned these were sold as a racing kit
and therefore designed to weigh far less than o.e. sets and also have the
adjustability to suit rider/track."
What relavence this quote has to the failure I am struggling to understand.
But never mind, my main concern is getting the bike back on the road.

Have you contacted Arrow directly?Here is an extract from the importers email,

I’m surprised as I thought Arrow had a very good reputation and I’d have thought if anything the Arrow rearsets although lighter, would be stronger than OEM ones and expected to take more abuse if they were ‘for track’.
I do like my Arrow rearsets mind.
Nickccc said:
No, I haven't contacted them directly I have been going through the importer.
I may as well give it a go I suppose.
I would, post the link to this thread in the email, maybe it will embarrass them into sending you a arrows hamper.I may as well give it a go I suppose.
Mind you I wrote an angry letter to mcdonalds for giving me outdated toys in my happy meal and they havent given me a reward yet!!!!

The fairings on my bike are attached via mild steel brackets.If you have a fairing go and have a good look at how it's attached to the bike. You'll see a long bolt made from this monkey metal. It will even have a hex attachment so you can remove after it's split.

Really?
If I strap some gear on the pillion seat, I often use the left foot peg to be able to swing my leg over the gear. In fact, I do it almost all the time.
I'm trying to picture this. Is the bike on a centre stand when you climb on via the footrest I assume?!If I strap some gear on the pillion seat, I often use the left foot peg to be able to swing my leg over the gear. In fact, I do it almost all the time.
I even do it on the sidestand, never bothered me nor the bike.On another note, how do anybodies pillion gets on his seat?
The OH has always put her first foot on the peg, putting all her weight on the one peg.
