For me racing a Norton makes Ken Kavanagh a hero, his real claim to fame rests in being Australia's first winner of a motorcycle Grand Prix. A feat accomplished at the 350cc UGP in 1952. Another of his notable wins was the Junior Manx TT in 1956. His career started with Norton but his highest international ranking of 3rd was with Moto Guzzi in 1954.
Ken Kavanagh came from a rare breed of racer that raced automobiles as well. He attempted to race in Formula 1 aboard his personal Maserati 250F. Unfortunately, he was unable to complete either of the two races he entered.
