Kart racing was more physically demanding than road racing motorcycles for me. The g forces you pull while cornering just beat your hole body up along with them just being skittish. They are always darting one way or the other and if you don't don't stay on top of them you wind up in the pucker-bush..

Yes incredibly physically demanding...
No suspension, and getting the frame to physically twist and get the rear inside tire to lift... The physically unfit need not apply..
When I talk to racers that race the whole Pacific Northwest they tell me our home track is the most physically demanding and technical around.. "if you can Master this track the others will be easy"...
