Yup - I know.
According to SHAD - No brackets for the R3 - any of them. There were not before either.
H&B do at least make a frame. And those cases have proven they work and stay on.
I did try using the SHAD with some QD adapters from SW-Motech. I was NOT impressed.
Tbh, if I were to re-investigate luggage options I would want cases that load from the top. If they're QD naturally you can do this with the cases removed from the bike.
I would rather bolt them on fixed.
