I saw him at the Goodwood revival races a couple of years ago, when BMW brought over some 1930s? Racers, the red leathers had stretched a bit!
It would be interesting to know what the spec of the IOM TT R90/s that he rode in 1973 and 74. I was their in 73, riding my Norton Commando, BMWs were way out of my price range in those days. Even then it was amassing how fast those guys went on a 37 mile road circuit.
