In the next GP, the Austrian, in atrociously wet weather, Jarno and Hideo Kanaya were again first and second. In the German GP Jarno was leading comfortably when he had to retire because of a snapped chain! The terrible crash during the 250 cc race in Monza a week later, in which Jarno Saarinen and Renzo Pasolini were killed, made Yamaha decide to withdraw from the 500 cc class for the remainder of the season.
