801 320mm brake discs

I changed my rotors to 320mm and there was a difference. The bigger difference was when I swapped on some Brembo calipers I had laying around from a Ducati monster. I’m sure if I did sintered pads it would be even bigger but it’s 2 finger braking with whatever pads were stock on a monster.

If I remember correctly, you changed the discs to some stock 1290 KTM/Galfer 320mm discs.
I read somewhere that the stock KTM/Galfer brake discs are all produced on a separate production line and aren't of particularly good quality.
The aftermarket Galfer discs, on the other hand, are apparently of much higher quality; comparable to the aftermarket Brembo discs.
That might be a reason why the brake calipers made a bigger difference for you.

A few years ago, I also replaced some original brake discs on another bike with a pair of Brembo Oro discs and Brembo sintered pads; although the Brembo discs were identical in size to the originals, the difference was nonetheless very significant.

Those are just some experiences I’ve had; others, however, may have had different experiences...

Yeah they are 1290 rotors. I am running stock dual 701 galfer discs on my 701’s mag wheel set up. They work great but do seem to be noisier than normal. They feel a lot different than the 1290s..
