    A motorcycle is unconstrained in roll motion, much as a chair with wheels is unconstrained about its vertical axis. A chair without wheels is not as useful a comparison.

    The same law holds true, but you'd have a hard time detecting the motion of the earth in response to you twisting in your chair. The masses involved are far too disparate.

    How can a motorcycle be unconstrained in roll motion? Would't that mean the tires were frictionless?

    What I'm saying is that the opposite force in question is being applied to the earth. In the case of a motorcycle the opposite force is applied to the motorcycle and the motorcycle exerts the force on the earth.

    I'm using "roll" in the aviation sense, motion about a fore-and-aft axis...leaning freely to the right or left.

    A motorcycle applies essentially no force to the earth when it flops from one side to the other when not in a turn. Its motion is completely free about that axis.

    An airplane is not a useful comparison as it does not have contact with the ground. The roll axis of a motorcycle is it's contact patch with the road.

    I'm not comparing it to an airplane...I'm just using the spatial term. (although both a bike and an airplane share a similar freedom of motion about their roll axes)

    Absolutely correct and there is the second point within the system that I have referred to as the riders hips which allow the upper body to move. Movements within this closed system do don't change the COG. It's like a hinged ruler. If the others just don't get this then they just don't understand the basics. If they do get it and are just trying to troll or bait then that's fair enough as well.:lol3

    WOW... I'm wondering how many of the prolific posters that are arguing physics and space walking are the faster guys in their track day or race groups????

    This thread is indeed chock full of fail.

    Well, it looks to me like the front wheel HAS castered just a little bit to the right in response to the slide. What we saw in the post above yours was a classic example of someone not exhibiting an understanding what is meant when most of us say "countersteer". There is no, zero, zilch, nada possibility that Casey didn't countersteer forcefully to get his bike heeled over like that, but in this picture we're simply seeing one of the freebies you get with any powered two wheeler. In a car you have to steer into a slide yourself, a bike does it for you. We just have to be smart enough not to 'correct' the machine.

    Riding my versys up along hill with a passenger. Two lanes going up, no traffic, going about eighty. Road is twisty. Making a hard left sweeper, then an immediate hard right. I CRANKED on the bars to make a smooth transition. This was countersteering and I learned it right here. It seems with leaning, I can only go so far. Countersteering makes the bike do more.
