Long travel forks.
Lazy head angle like a tourer.
They sag when you are on the bike and it gets more racey when you sit on it and compress the forks an inch or so, they are set up that way so the fork extends down into bumbs and dips as well as compressing off the bumps, get off and it kicks it right back.
That and the fairly rigid disc brake hose will keep the steering straight as well.
