I've seen this argument a few times, and each time it's struck me that perhaps it's just a question of semantics, all adding up to the same thing.
My take is that leaning shifts your center of mass on the bike, which changes the force vector on the steering head, which causes the front wheel to change direction - particularly at lower speeds where those small forces have less (cycloscopic?) inertia to overcome. If the steering head were unable to shift direction (i.e., respond to the change in force vector), would leaning changing the direction of the bike? I don't think so. If it would, I think that would constitute real "body steer," but I sure don't understand the physics that would create that effect. Does shifting your center of mass on the bike assist in "hand-actuated" turns? I think so, because you're using the change in center of mass as a turning force in addition to force you exert with your arms on the handlebars. However, that alone does not, in my opinion, constitute body steering. My .02. Tom __________________________________________________ Do you Yahoo!?
