    So at 11K miles, my 1290R front brake rotors are junk, and apparently considered a wear item by KTM- No warranty coverage. Does anyone know what other models use the same brake rotor? I assume 1190 R/S models may , and I plan to look up a few part numbers, but thought maybe someone would know right off hand. Super Duke R? 1290T?

    SDR rotors are 320x5 vs 320X4,5 on the SAR. Not sure if they are compatible. SAT are identical.

    thanks. so the SDR is .5mm thicker...maybe what is needed. I have not tortured the brakes at all but the rotors are warped enough to be annoying already

    Pretty sure the SDR rotors won't work. But I'm sure Brembo makes something more robust. Plus you can upgrade to a set of M50's while you're at it.

    Also, what makes you think the rotors are warped? The bike has a floating caliper that causes a slight stutter when decelerating at low speeds. Been told, by my dealer, that that's "normal". Thought mine were warped after my get-off, maybe that's what you're feeling?

    “Braking” makes great replacement wave rotors. I’ve had a set on my 1190R for 10k miles

    yeah, I would advised to scuff up the front rotors really well and possibly change brake pads.
    My rear had a weird pulsation from my stock Brembo pads, a good scuff and new EBC pads cured my issue,
    You'l upgrade your pads anyway, couldnt hurt
    good luck

    Confirmed. SDR rotors are totally different. Got 1290SD and 1290 SA in the garage.

    It is pretty easy to detect rotor warpage, the herky jerky thump thump thump that makes just coming to a smooth stop difficult is one little sign lol

    I scrubbed, cleaned, and cursed my OEM rotors and gave in last year and went with my current Braking waves. Absolutely smooth now

    Mine were badly warped or so I thought. A good scrub clean and new ebc sintered pads - suddenly no more warp feeling. Magic really!

    Nope. Scrubbed with a kitchen brillo pad. The issue is a deposit of old pad material creating a warped effect. One could use a fine grit waterpaper instead.

    @Capo Rick can I ask which Braking brand rotors you installed? They have a few models. I'm thinking of replacing my 1290R rotors. Had the same issue with my 1190, not covered under KTM warranty despite being within a year and low mileage. They consider them a wear item, a costly one, but a wear item nonetheless. Same issue now with my 1290R.

    What can happen is pad material gets left on the disc if you brake to a halt and leave the brakes on after you stop. I've also read the theory that long, light, braking to a stop can also leave pad material. This gives the impression of warped rotors.
    What can also happen is corrosion from road debris can cause the buttons that allow the disc to float to stick. Some riders will lube the buttons and put a suitably sized wooden dowel in a drill, stick the dowel in the button and spin it to make sure it's freed up.
    It's actually pretty rare that modern floating discs warp in street usage.

    my rotors look like bare shiny steel. no deposits of anything. my bike is spotless and there is no corrosion anywhere, so I dont think deposits or corrosion are causing the issue
