Graeme Lawrence and John Macdonald came in second and third respectively. The Motorcycle GP was won by Bill Molloy in his Kawasaki 750.

He said he could not understand the allure of such events, “driving around and then going into the pits; after that, changing the tyres and revving out again … makes no sense to me.” Motor racing was banned because they were thought to promote reckless driving.
