Career
Ito began his Grand Prix career in 1960, although he was a Factory Yamaha rider as far back as 1957 where the Yamaha YD-A & YD-B 250cc machines were so devastating in the Asama highlands race, where Yamaha took the first 3 places with Matsuko on a YD-A taking the honors. The machines were later modified for the 1958 Catalina General Practice in States with smaller fuel tanks taken from the YA 125 machines, high pipes and high footpegs. Ito was the Star rider of the team and the only Japanese rider alongside four local American riders.
Ito finished 6th, even after an unscheduled pit stop for a fouled plug.
