| I can only say that my experience of riding a slower and smaller bike in S-o-T classes was that it was a pain despite split grids, delayed starts etc. Inevitably, slower riders on faster bikes resulted in traffic jams, near misses and lost lap times. On several occasions I lost places because of it and in the end resorted to having to be pretty hard on some riders in order to make a move stick so, I could get on wth the job of racing/chasing after a fellow minitwin rider.
Separate races is the only sensible solution. |
