I think is fair to point out that the original idea for a Post Classic race at the MGP came from the MMCC and was supported by the MGP ambassadors at the time. The rules then where much discussed and while not perfect they were at least reasonably fair and under review.
The DED came along denied the MGP and the MMCC any kind of support and in fact did all the could to destroy the MGP and MMCC. Remember the Save the MGP campaign.
The Classic TT was created with rules to suit certain wealthy individuals with not a care for those riders who had originally supported and ridden in the Post Classic MGP races and many bikes built for that class suddenly became redundant.

The DED care not a jot for racing or racing classes or rules. The only thing they want is so called superstar riders riding round of anything that look vaguely old in order to bring in so called fans and more importantly their money. ALL of it on the backs of free labour.

At least Turpin wore a mask.
