Ray Owen was actually riding a 500 JAP to win the Unlimited title in 67, sorry Alison.
I don't know what 125 he was riding, I'm in contact with Les Burdus, he won the 500 ( Senior ) title the same year, he finished second in the unlimited.
Les rode my fathers bikes for a while and was riding dads Tiger 100 Trumpy to win the 7 Hour race at Muswellbrook in 62.
We're all looking forward to seeing you ride that at the Titles Doc.
