The Yamaha YSR50 is a miniature motorcycle that was produced and sold by Yamaha during the late 1980s and early 1990s. The bike featured an air-cooled 50 cc (3.1 cu in) two-stroke engine. The engine was sometimes swapped out for a larger variety.
The first production model came out in Japan of 1986, and had the looks of a re-shaped and scaled down version of the YZR 500. It had a front disk brake and a rear drum brake.
The motorcycle also had a 5 speed transmission, the US had a very hard time considering the Motorcycle as a Moped because of the 5 speed transmission.
