I don&#x27;t have enough intuition for gyroscopic precession to fully follow your high speed case (how fast, I wonder?), but the requirement to overcome gyroscopic stability otherwise causing tracking off line convinces me that I&#x27;m wrong at higher speeds. I still think my picture is more explanatory at the speeds I commute at (almost always below 45mph, with most steering at sub 25mph).<p>How do braking forces play into this, and do you know what kinds of speeds we&#x27;re talking about? A soft front tyre (i.e. lower than normal pressure) has a dramatic effect on handling at street &#x2F; city speeds - the extra rolling resistance makes the steering want to steer further into the turn, causing a countersteer upright. So you need to fight the steering to maintain line. But of course when putting a bike on track, you run with lower pressures as a matter of course - and I know from anecdotal experience that it is possible, on track, to brake while leaned over a bit hard enough to start lifting the rear, something that would require an immense effort to avoid straightening up at street speeds.<p>You&#x27;ve given me something to think about, but unfortunately I won&#x27;t be able to solve the problem without either learning a lot more mathematics, or playing with models...
