Thanks for the great pictures and memories of the Manx GP.
I can remember the rotary Norton being raced under Death cigarettes sponsorship, really fast and fairly reliable by then.
Loved the Bimota, my brother had a KB3, tuned to within an inch of it's life for endurance racing, very frightening as it had skinny tyres which were hard to get hold of.
And I agree with the favourite, the 175 looks great
