Yamaha RD250
The Yamaha RD250 is a two-stroke motorcycle produced by Yamaha Motor Corporation between 1973 and 1987.
Four generations of RD were produced: the air-cooled models from 1973 up to 1979, and from 1980 until 1987 the liquid cooled models; known as the RD250LC, RD250LC-II and RD250 YPVS. The name RD stood for Race Developed.
The standard bike weighed 152 kg dry and had a 247cc 2-stroke twin engine that produced 30 hp. It had a 6 speed gearbox and chain final drive.
In 1981 the UK government reduced the maximum cc for learners to 125, killing off the 250 cc motorcycle class in a stroke.
