I owned a motorcycle for a grand total of one month. Obviously, I didn't race.
Although I'm a car guy, 2-wheeled riding basically scares the hell out of me. And I have great appreciation for the skills and guts of those who race them.
Whether now or years ago, my guess is that it's basically the same thing: wring the very best performance out of the bike AND the rider. And do it all the time- every time.
That's gotta be a challenge.
