AI does not know much about motorcycles. If you discuss a technical issue with it, you get the popular myths. If you watch the following video, the guy in it adjusts his trail by changing his fork yoke offsets one millimetre at a time, and that is sensible. However a bigger change gives a bigger response, and the change is much more significant. Some things need to be done at lower speeds to detect the response, before going faster. With steering geometry, a problem can suddenly arise from nowhere and grab you. It is dangerous to generalise from information from changes which are not systematic and progressive. In Tony Foale's book on handling - he says the extremes of trail are self-steering. I think that is correct. However on this forum, some people do not seem to recognise the importance of braking and accelerating while on a lean. So the sum total of the information supplied by AI, also includes influence from those people. -
