Yes indeed ....
So lets re-phrase a 'stable' bike and rather than worry about gyroscopes think of a stable bike as ..... a bike with 100% Tyre Grip!
Have you got the bike in a place where you have 100% tyre grip? Is a rider excessively and unnecessarily leaning the bike and so compromising his tyre grip trade off?
If we think of grip as '100 units', then we can apply those 100 units to a stoppie, a wheelie, or Mark Marquez lean angle. But we cant do a stoppie with lean angle because we overload our 100 units.
So there is a relationship between what you can do with the gas (or brake) and lean. If we imagine our tyre having 100 units of grip available to us, our racer who trail brakes applies 100 units of brake in a straight line. As he begins his lean into a bend he lets off 20 units of brake (now = 80) and apples 20 units of lean. As he lets off 40 units of brake (now 60) he applies 40 units of lean, when he's at 10 units of brake he's at 90 units of lean. When he's off his brakes he's at 100 units of lean. I know this is Janet and John, and nobody is reading this and having an eureeka moment (!), but its a good analogy and a good way to think about grip.
So lets use that analogy in a swoopy overtake V a squared off overtake as an example.
If the classic sports bike GSXR rider does his usual swoopy overtake, he swoops out to the offside to start his overtake. He's leant over whilst he's accelerating, the bike is being dragged too far to the offside and he cant actually apply 100 gas because he's leaning at the same time. It feels quick to start with (flick out with a swoop, yeah baby...) but actually its quite slow in the long term and mildly risky because he's balancing lean and gas. Wet road? Sports tyres? Minimal tread on the edge of the tyre?
A 'squared off' overtake sees the rider walk the bike out laterally. Upright. We just move the bike to the right and keep it up right. We haven't gone forward yet. Now I can apply nuclear fusion to my overtake because I have 100 units of grip. BANG! Gone. That style of overtake feels slower to start with (because I walk it out first) but I more than make up for it, because of my 100 units of grip for forward drive. (There is an added bonus that if having walked out I dont like it, I just walk back in. The swoopy guy has gone forward from the get go and has fucked any return if it was a bad call!).
So thats a simple example of Grip, of how the 100 units idea helps us in everyday biking and how by not swooping, ive actually been safer, more stable, quicker, and more efficient. All because i put the bike in an upright position before applying gas.
If we're swoopy, we're constantly at lean so we're constantly juggling out 100 units. I know swoopy can be 'fun'.( i have a mate who fucking swoops everywhere!! But he's slow!! he's always leaning over! 'Yeah but I like it'!!), but if you want to enjoy the performance of a motorcycle, understanding swoop and its compromise to grip is quite important.
