What kind of clutches were the top riders using. I don't know if it was the sound on the Red Bull videos but there didn't seem to be much of a link between engine sound and clutch lever action. Rekluse?

I think some only use the rekluse case. Not the mongo clutch as well. The case is stronger so means less damage and the greater oil volume helps longevity by keeping it cooler.
