Having just done a track day at Phillip Island on a previous-generation bone-stock BMW S1000RR (no winglets), I now see how the winglets would help. It's trying to wheelie the whole length of the front straight. At that track, even backmarker me is coming onto the front straight at 180+ km/h in 4th gear with the bike trying to wheelie, and it keeps on trying to wheelie the whole length of the front straight until I shut off. It could use some aero help to keep the front down. I can't imagine what would happen with even more power and less weight (Superbike treatment).The winglets help to limit wheelies on acceleration??? Wank, wank, wank. By the time the bike is going fast enough that the winglets do anything, wheelies aren't your biggest problem.
