Yes it should. Who, on a 15 year old Jap sportsbike, would be happy at riding out with a load of pre-war bikes? I don't see that's enjoyable for anyone, and the VMCC in trying to be all things to all men, have potentially spoilt it. The older bikes won't bother to come as they can't keep up with the 15 year old bikes, and the Jap riders will give it a miss as the older bikes will be too slow. The worst of all worlds for everyone.
If someone had one of those 'orrible 'Onda CBRs there must be better clubs to join or rides to ride, surely?
