In the evidence of this, racing bikes - no, riding bikes - is butt-blistering, ball-bruising hard work. You know all those car racing conventions you’ve ingrained into your consciousness? Forget all of them. That one that says you can brake and turn at almost the same time to skid through a corner sideways for maximum style and speed means jackshit here. And the one which guarantees that you can easily correct a momentary wobble of the steering wheel with the minimum of fuss and not have a major spine-shattering accident doesn’t apply with bikes.
