Ok. I will give deference and believe any of you who says clearly here
that you knew the answer to my question about turning with no hands, was "counter-steering".. If you choose to state that here... Otherwise, I will have to assume, you all missed it for whatever reason...Later guys, time to get back to work.... |

No hands[edit] This is how countersteering works when riding no-hands. To turn left, a rider applies a momentary torque, either at the seat via the legs or in the torso that causes the bike itself to lean to the right, called counter lean by some authors.[8] The combined center of mass of the bike and rider is only lowered, of course. However, if the front of the bike is free to swivel about its steering axis, the lean to the right will cause it to steer to the right by some combination of gyroscopic precession (as mentioned above), ground reaction forces, gravitational force on an off-axis center of mass, or simply the inertia of an off-axis center of mass, depending on the exact geometry and mass distribution of the particular bike, and the amount of torque and the speed at which it is applied.[6][15] This countersteering to the right causes the ground contact to move to the right of the center of mass, as the bike moves forward, thus generating a leftward lean. Finally the front end steers to the left and the bike enters the left turn. The amount of leftward steering necessary to balance the leftward lean appropriate for the forward speed and radius of the turn is controlled by the torque generated by the rider, again either at the seat or in the torso. To straighten back out of the turn, the rider simply reverses the procedure for entering it: cause the bike to lean farther to the left; this causes it to steer farther to the left, which moves the wheel contact patches farther to the left, eventually reducing the leftward lean and exiting the turn. The reason this no-hands steering is less effective on heavy bikes, such as motorcycles, is that the rider weighs so much less than the bike that leaning the torso with respect to the bike does not cause the bike to lean far enough to generate anything but the shallowest turns. No-hands riders may be able to keep a heavy bike centered in a lane and negotiate shallow highway turns, but not much else. |

The no less than 7 times I posed the question to you and the group over the last 18 hours about "making corners with no hand pressure to the bars" and specifically asked you "what that was called".. that despite mocking, and dodging, you actually knew the answer was "counter steering" before I gave you the answer. That you didn't just go back after I finally told you the answer to the question and find a part of one of your links that supported it? Is that what you are saying? Please be specific, with a simple yes or no.. thanks... |
