Now some facts about real racing ...
1. If you're really fast it doesnt matter so much what you ride cos you go past everyone on the corners.
(eg I ran my 450-single-road-bike at a brands track day and passed bikes on every corner)
2. If you have a really fast bike it doesnt matter if you're not so good on the corners cos you overtake everyone on the straights.
(eg see eg above ...)
3. (1) + (2) = racing
4. If a race-grid starts with the class-leaders at the front then they will probably clear off again.
This is NOT racing imho, and the guy at the back with less bottle or a slower bike will give it all up after a few races, as he will not be having enough fun.
5. If the grid is random, or has the class-leaders handicapped, the (poor) guy at the front will have butterflys, and a good time !
