You would think any little bit would help at those speeds. MotoGP bikes are breaking 200 mph regularly now.
Compared to a Busa or ZX14, the MotoGP bikes are tiny, with much less frontal area and are designed for a smaller rider. Larger production "high-speed sport tourers" are a compromise - that's why the larger rider gave a better coefficient of drag.
Another interesting thing the "speed hump" does is provides a spot for a battery-powered fan to drop-in to cool the rider off the track.
