The mount point on the GSXR rearset is further forward, and the SV brake line was not long enough to stretch that far. I had to make a little bracket to keep the cylinder in the same location as stock.
I don't know about anyone else, but I am very happy with the Vortex rearsets that are made for the SV650S. Mine is '03.
I still have yet to wire the rear brake light to the pressure switch but the work, feel and perform great!
