Like sitting up for drag...During the broadcast of one of the Motegi races one of the commentators mentioned that one of the riders, Tony Elias maybe but I'm not sure, tested the theory and said it did help with turning the bike
I'm gonna claim the "leg dangle" technique.
That was a heated race between the two of them. The leg didn't seem to phase lorenzo, he looked like he was gonna take rossi's leg off a couple times haha.The commentators just mentioned at the last race in japan that Rossi was doing it (as well as others) to prevent passes from people behind them (i.e., Jorge Lorenzo). I don't like it (unless for reliveing a cramp) but it's part of the game.
