The Yamaha TDR 250 is a dual-purpose motorcycle manufactured by Yamaha between 1988 and 1993. It is powered by a two-stroke parallel twin engine utilizing the Yamaha Power Valve System (YPVS). Designed to provide agile handling and quick acceleration for both on- and off-road use. It was the world's first two-stroke to use a CDI ignition and digital advance system [1]
The engine is essentially a Yamaha TZR250 unit with a modified power delivery to suit the TDR's intended use [2] - many of the parts are interchangeable. It was originally released in a 250 cc format and a 240 cc format exclusively for the French market.
