TL;DR: Anyone discover another rr disc that fits? :Shrug:
Can’t find much (anything) on floating, oversized, nor cross-compatibility w/ other sport bikes’..
Called Galfer, no luck.
Seems we’d need a ~90mm inner hole; 220+/-outer..
Personally, I’m after the XB/1125’s 10” (254mm) diameter, ideally, for my custom, but the holes don’t quite line up due to the aforementioned 1190’s bigger “hub”.. And I don’t want to fab much, or go the machine-shop route unless I have to!
