To lean or counter-lean, that is the question...

[QUOTE="torch, post: 1460759, member: 1295"] I wonder if there is some confusion over terms in this thread? Counter-steer and counter-lean are two different things. Counter-steer induces lean of the motorcycle as a direct result of Newton's laws of motion and gyroscopic precession. Basically, the front wheel is a big gyroscope. When you apply a force perpendicular to the axis of rotation, the reactive force is at 90° to the input force. IE: apply clockwise force to the spinning front wheel and the axis of rotation will itself rotate counterclockwise with equal force, taking the rest of the motorcycle with it. In other words: turn the bars right to lean the bike left. Note that the front wheel has to be spinning to have angular momentum. Obviously, sitting at a stop, rotating the handlebars has no effect on inducing a lean. The effect becomes more noticeable as speed increases and counter-steering will lean the bike regardless of your body position. Counter-lean, as I always understood the term, is bending the upper body at the waist opposite to the direction of motorcycle lean, so as to be more vertical in the corner than the motorcycle. As compared to leaning with the motorcycle. In the second video posted, Ryan F9 introduced me to the term "counter-sit", which seems to take the idea of counter-lean to a whole new level. He's shifting his backside off the seat as far as any racer hanging off and dragging a knee -- but in the opposite direction. Since watching that video, I have tried it a bit -- mostly in an empty parking lot -- and can see the value to a motor patrol cop. For a fast, tight U-turn or maximum maneuverability at moderate speed in tight places it's probably the best approach. A good tool in the toolbox, but I don't think it's the be-all and end-all that should replace all other riding techniques. But that's just my 2¢. [/QUOTE]
