I know of 2x1190R bikes here in PE that got new fames.
Secondly, and I'm not trying to kak on anyones head, but how many times did we talk about the DNA filter story and said IT DOES NOT CURE THE DUST PROBLEM.
But still, everybody fits them, or trusts KTM when they fit them for you......
The dust thing is not new to KTM Headoffice. I run the Unifilter, so on my 15 000km service when they opened the airbox it was CLEAN inside. The guy told me, if there is dust, they check the shimming, if its clean like mine, they dont check it.
So even the Meccies are aware of the dust story. Here in PE at least 4 engines have been swopped, and thats the ones I know about, there can be even more.
