I'm a beginner with some dirt experience and while none of us know for sure, I'm surprised by the amount of confusion on this. I guess the first time I saw this I just took it as the riders resetting themselves. I know I'm not fast, but I am very comfortable on my gyroscopic bike. If I can picture myself being super fast and very skilled for a moment and I was coming into a turn and needed my leathers to shifted, my butt placed in a different position, my balls of my feet shifted, I could see doing this move and I could see enjoying doing it. It would let me know I was set up just right for the turn ahead. It seems like if youre comfortable doing it, it could be a lot more effective than trying to slide this, pivot my foot here, etc. Why not just start all over again and get the body positioned correctly without trying to do all this minute manuevering?
