I saw it. They said the triple clamp broke. I moved on.
Yeah..they put some new ones on...
Why would you buy orange when you can buy yellow....
what would you like to discuss? (not trying to be a smart ass)
my perspective is, It seems his steering stem broke. its happened to people before, will pry happen again unfortunately.. glad he wasn't hurt and was able to race the night show!

Whose clamps?
I read the bike went flying, which is why stuff broke, not that stuff broke and caused the bike to go flying.
Stock.
That's never happened before on a KTM group bike.
Nobody is talking about it cause the frame is fine as shown in the first photo. Every nerd has jergens next to their computer scouring the internet for ktm frame failures.
No bike goes into press day hoping to come out of it in a skid steer.
Made in China
Good time to grease the neck bearings...

If that happened to a Stark Vitards would have created 10 new threads to show it broke cause the haters are gonna hate.
I am assuming the poster maybe was getting at that?
Because orange still make 2 strokes.
😂😂😂
My first chuckle of the day. Thanks man.
So the implication is that KTM group uses cheaper parts on their gasgas bikes, which is true. The moral of the story is: use better triple clamps than stock.

First off, it's good to see that Varize is OK and went on to race the next day.
The clamps that failed in this case were the WP Powerparts clamps. They're stock on the factory edition, but I wouldn't consider them stock in the general sense. Most people are buying these as aftermarket parts to upgrade the clamps on their non-factory edition bikes.
I do find it interesting that when it was our clamps that failed in this manner, it was a huge ordeal with multiple posts, Instagram mentions, podcast interviews, etc., but when it's a KTM/WP part it's not such a big deal and not much of anything is mentioned. Interesting...
And while I don't know the details of the failure on Varize's bike, whether it caused the crash or it was caused by the crash (I'd suspect the latter), it's pretty clear it failed at the stem/clamp interface with the pinch bolt design, which is the typical failure point of this general design. Our new Gen3 clamps have done away with the pinch bolt system and now use the "traditional" style double nut stem:
This is a much stronger and more robust design which solves that issue entirely.
Excellent, that looks like a work of art!
They are using traditional racing engineering. If it breaks, add material to make it stronger, if it holds up, remove material to make it lighter. LOL
The video where that image is taken from, Varize's mechanic said that he endoed before the clamp broke. That's what it sounds like happens in most cases for the other pinchbolt-style clamp failures. With an impact to the front wheel, the forks act as lever arms and the bottom clamp/ stem bearing is a fulcrum. Pushing the front axle rearward effectively forces the top clamp forward (off the stem) and the pinchbolt fails in tension. That's my theory from my couch. The impact from a crash is outside the design envelope of normal usage (i.e., stresses gathered while riding x factor of safety) but nonetheless a crash is a forseeable and probable event. I like those new Luxon clamps- beautiful!
Billy its cause Vital expects it from KTM, not from Luxon.
I cant believe no one has posted Pings bike yet.
Sounds like the moral of the story is, if your top triple clamp utilizes a pinch bolt to clamp the triple clamp to the stem, you should replace it ASAP. It seems like there is enough evidence that this is a dangerous design. Why is it still being used? The more traditional design without the clamp is tried and true and doesn’t show up in a catastrophic failure thread on Vital every few months.
