Ever since Valentino Rossi let his leg fly free in the wind, people have been trying to explain the advantages of the “leg dangle” in motorcycle racing.

While many reasons have been offered (some more accurate than others), and while some pundits have certainly painted a good portion of the picture behind this growing technique on the race track, we have never seen someone explain the subject quite as well as Sylvain Guintoli.

The Frenchman posted his explanation in a video to YouTube, and he is not only clear in his explanation, but also exhaustively comprehensive in his analysis on the subject.
