Not threadjacking. Just guiding you to some reading to answer your questions so we don't have to sit and type it all out again. Tails and rudders were considered at length.

The Tony Foale pages were very ingenious to show that trail, not rake angle, is the active ingredient in making a motorcycle stable regardless of rake which is really just set as a compromise between withstanding the bending forces that are trying to push the wheel back when you hit something, and the weight of the bike trying to bend it forward. But I disagree with some of his statements regarding longitudinal center of pressure and long tails which are true for an airplane but are more complicated and counter intuitive when you still have two wheels stuck to the ground that are far and away the determining factor on the path of movement.

The interesting addition to the conversation that was brought up in this thread was the nose foiler. I wonder if that is why many modern sport bikes have some sharp protrusions in the front bodywork on either side of the headlight?
