how the hell did you come up with using your thigh to hold 100% of your body weight, that doesn't even make sense based on the slope of the tank where your thigh touches. The load is distributed between the feet, butt, thigh, elbow, hands and where ever else your body happens to touch the bike. No matter how much anyone wants to say differently, those are the points of contact with the bike so they are all going to have some type of load on them. You can distribute it however you want. No one said the knee had to be in the tank to create stability. You have leverage backward, using the knee would require MORE force than using the inner thigh, just like he is doing in the picture. You are only applying pressure to keep your body stable, not to support a huge % of your body weight...your body weight will be driven down through the the plane of the bike for the most part, supported by the seat, pegs and some weight on the bars. My leg is in a better position for grip on the side of the tank if I stretch it out; put your foot in your boot, sit down, lift your leg off the ground and extend your toe. It has nothing to do with loading, the physics of the bike going around the turn or anything else....the boot resists the motion of extending your toe. Add some weight onto it(just like you do by putting your foot on the peg) and it will become even worse. It sounds like you guys just want something to argue about.
