Maybe. The power delivery on the 650S and the 650R is different. It comes down to preference after test rides.
I think the SV650S has linked front brakes instead of a separate line to each caliper? I read something about doing a brake swap on those because having one brake line to one caliper and then one brake line to connect the calipers doesn't brake as strongly.
I'm a fan of the SV650SF though.
