TBH maybe we're being a little harsh on andyb, if he can hold his own on a VFR400 in the fast group he is running 400 race winning pace and if we're not careful he'll turn up in DD and show us the way round !
As others I would like to know when I turn into a hardened racer and have to go in the fast group ?
Most DD'rs lap cadwell in the 1m50-2m10 lap times, fast groups now drop down to 1m35, admittedly only a few secs quicker than andyb on his 400 but still for dd bikes the lap times are too different and cause a danger especially o nthe straights with closing speeds of more than 60mph.
The dd bikes don't have a corner advantage over the bigger bikes either, unlike motogp where a 125 is lighter than a motogp bike and they are both on equally grippy tyres the dd bike weighs the same as a modern litre supersports yet is on less grippy tyres, dd bikes are just a liability in the fast group.
Inters is a safer place to be, folks in inters on bigger bikes don't know how to open their throttles and don't use their sticky tyres in the corners so lap times are similar therefore making the day safer for everyone
So what was the problem with racers in inters ?
