Isao Morishita

Isao Morishita is a former Grand Prix motorcycle road racer from Japan, whose name is written in Japanese as 森下 勲. He began his Grand Prix career in 1962 and enjoyed his best seasons in 1963 and 1964, when he finished fourth in the 50cc world championships. The English Wikipedia article on him is very short and gives no birth date, so this entry records only his nationality, the start of his Grand Prix career and those two fourth places.
