I have experience with the SAs at track days, but not on the S1000RR. Mine is that the tires, particularly the rears, are quite sensitive to tire pressures, and that those tend to be higher than others. Specifically, if you get a sensation that the tires are turning in at different rates - like the front of the bike is dragging the rear into the corner - you probably need more rear pressure. If you get them right, they work really well, but they don't like to be set too low.
I ran them at 32F/36R *hot* pressures - if I recall correctly that translated back to 29/32 cold, but that will depend on bike, rider, track, and weather.
