You do realize that WERA has SEVERAL superbike classes...and surprsingly enough, Ducati's do and have won in several of them.
I am not saying that they don't. And there are some excellent riders on them. I am just saying that fours seem to win more often.
Although "threes" do occaisionally...I still haven't figured out why they get to run with "two" and "fours"?
Because Lightweight Three-way and Heavy-weight-three-way have different meanings to different people....
