Kevin Cameron, brilliant as he is, is just wrong about this.
The Wright brothers (bicycle makers before anything else) were the first to describe the physics of single track vehicles and how countersteering makes bikes turn.
What happens when you yank the wheel of your SUV to the left while driving? The body rolls in the opposite direction, to the right. That's just disconcerting in an SUV, but on a motorcycle, the effect is to roll the bike onto a coned part of the tire... that's how the corner is initiated.
Gyroscopes got nothing to do with it. To prove it, motorcycles have been constructed with counter rotating sub wheels to cancel out or even override the gyro effect. Guess what. They still turn just like a regular motorcycle.
Gyro shmyro. Even Kevin Cameron can make a mistake.
