First introduced in 1963, Yamaha’s YG1 proved a popular small roadster that performed well with it’s 80cc single cylinder rotary valve engine, four speed gearbox and a monocoque frame design with telescopic forks. Nippy, practical and good fun to ride, by the time the seventies came around the design was looking dated and this ad from 1974 shows the final model designated the Yamaha YG1-F.
