As far as the racing position is concerned, that is where you completely have me. Nowhere on the street is it required to tuck down under the screen to get that extra .1 of a second a lap, and that part of it is well, just "fun"And in a strange irony, the clip-ons and racing position on a sportbike is actually more comfortable for me because of my back injury and the fact that an upright position transmits more shock of the road straight up my back and can be very painful at times. Leaning forward put more of a transverse load on my back and is far more comfortable.
This. Got a compression fracture of a vertebra years ago. Leaning forward keeps the energy from traveling straight up my spine where the disks have to absorb the shock. And I do raise my ass and use my legs. The thin seat and stiff suspension provide superb road feel but not so good for the back. I'm pretty tall and can sit up straight on a sportbike. Doesn't really feel good. More head buffet and noisier too, at least on some bikes. On my two recent 700 mile days on the Gixxer, the tuck made my ride so much better.
