Yamaha 125 RD History and RD 125 Yamaha Models

The Yamaha RD 125 is a small lightweight street bike that Yamaha introduced to the market in 1974. It combined proven 1960s popular design and structure and RD refinement. It has evolved from the AS3 series with just slight engine modifications. Same as its RD 250cc and 350cc cousins, RD125 has twin cylinder 2-stroke air-cooled engine, yet the old style front and rear drum brakes. Over the years it received an upgrade in form of reed valve top end, new look - coffin shaped tank and square seat (Yamaha 125 RD 1976 models onwards), several brake calliper modifications and in 1978 on the E model cast wheels.

Yamaha 125 RD production continued steadily until early 1980s and then replaced by the water-cooled single cylinder Yamaha RD125LC in 1982.
