Quite agree Colin there should be a World Championship series for all cc classes for Road racing.After all it would just be returning to what the original championship series was all about MOTORCYCLE ROAD RACING when the series was run over predominantly public roads during the 50/60s period.
However the event would have to extend beyond the IOM and Ireland and even now beyond Europe.
If there was the will of the governing bodies to organise it I am sure it would have more relevence to the manufactures than the current WSB, BSB and GP series.
But once again money comes into the equation.Gate receipts from public road areas could never produce the revenue a WSB or GP event at Donnington or Brands where we have 100,000 plus crowds each paying in excess of £30. to enter a private facility.
I do'nt think the governing bodies of motor cycle sport no longer have the ethusiasm for proper motorcycle road racing.
