You have any machinist measuring tools? If you put a dial gauge on a magnetic mount on the brake caliper and set the tip of the gauge against the rotor I would be very curious if you see zero runout.

Damn, this is beyond disappointing! I do really hope they'll get it fixed! The Brembo discs are working absolutely fine.

Since the brake discs are floating, a minimal tolerance shouldn't really be relevant at all.
I suspect that the material of many Galfer brake discs is simply faulty/unsuitable and warps due to the heat during braking.

Discs are floating for expansion, not transverse motion. I'm wondering if the hub isn't perfectly perpendicular to the axle. You wouldn't notice it as a wobble in the wheel with a tire on it, but a couple thousandths of wobble on the disc vs pad face would be an issue. If they machine a batch with an axle error it would explain why some people have had this issue.
The problem exists on various KTM models (with alloy wheels and also with spoked wheels), all equipped with Galfer brake discs. Several people have repeatedly received new Galfer brake discs, only to have them warp again. The mounting surfaces of the rims were also machined flat on several bikes; yet the brake discs still warped. Some then installed brake discs from a different manufacturer and only then were they able to truly resolve the problem.

I didn't know about switching rotors making it better. Even if the rim rotor mount surface was machine flat I would assume it was done with a setup that assumed perpendicularity between the axle and the flat part of the hub, so that still wouldn't fix an error where the axle path was machine incorrectly (ie the only real way to do that would be on an absolutely massive lathe, not a mill).
My front discs are acting up again so my dealer will have a look at it again. Also my dashboard is flickering and showing stacking GUI elements whenever its cold outside. Another thing that has popped up is that neutral as well as getting it into second gear is a lot harder than when the bike was new. Finally the retaining ring by the quickshifter is very rusty, almost rusted through.

Wow! Keep us updated about those issues please.
Regarding the flickering screen, I also have this issue. It doesn’t happen frequently on my bike, maybe 1 out of 10 engine starts.
Turning the bike off completely and restarting resolves the issue 95% of the times.
I also have the impression that it happens iwhen I start te engine directly after turning the key. Waiting a bit to fully initiate the electronics before starting the bike, seems to help. At least that is what I’m trying now.

A "reboot" does not help in my case. But having the heated grips turned on seems to make a difference (havent had it happen when turned off), I'll try to switch to a new battery and see if it could be that the voltage dips below a threshold that makes the electronics unstable.

Hello, this is my first post on this forum. I want to share the warranty issue I had with my new stock Svartpilen 801. I commute with my bike almost daily except during the harsch winter months. I reached 11.000km on the odometer recently. Had the last official service at the dealership at around 7500km.Suddenly the bike didn’t want to start. The starting engine was turning and I heard a few beats but the engine didn’t go on. The TFT said Traction Control Failure. Removed the battery, charged it, tried again, no solution.
Contacted Husqvarna Road Service through the App. They sent the national roadside assistance to my home, tried to start it with the booster, no solution. They arranged a recovery service and my bike was brought to the nearest dealer (where I bought the bike last year).
3 weeks (!) later I got the bike back.
The diagnose said it was a problem with the ride-by-wire system. They changed the original battery and throttle, didn’t work, then they changed the complete throttle body. The solution. The bike runs again. We have no idea how this could happen.
An electronic sensor problem within the throttle body was the reason the bike didn’t want to run anymore.
I’m happy it is fixed under warranty and I am happy with the Husqvarna Road Service, however 3 weeks and a few phone calls were really testing my patience during this beautiful summer period.

3 Weeks is a crazy long time. Glad you got there in the end. Glad we have 4 year warranties!
My 2024 801 (now still at about 5.000km) is still running fine without any major issues, but nevertheless it's quite disappointing/pathetic that so many already from the Duke 790/890 known issues and quality problems still exist; now also with the 801. The KTM/Husqvarna quality control seems to be still quite crappy...
By the way, my 2016 BMW R nineT is now at about 30.000km; and since day one without any faults or issues; not even the slightest! even the battery is still the first one and is still working fine; after ten years!!
