If you don't want to notch the wheel, you could just replace the disc bolts instead...
I always get the nomenclature wrong, but I think they're BMW "S1000R" disc bolts. I used some titanium ones off eBay, but you could also use OEM BMW. There's enough clearance on the other side for flanged nylock nuts--at least there was on my 3rd gen.
Ciao,
This is brilliant. I just ordered some BMW bolts to do this.
