It was powered by the naturally-aspirated, crankcase reed-valve inducted, liquid-cooled 249cc parallel-twin two-stroke engine from the first generation TZR250 (this same engine also powered the R1-Z). This engine featured the 'YPVS' Yamaha Power Valve System, CDI ignition and digital spark advance . Almost all of the engine, gearbox, and electrical components are interchangeable with the TZR and R1-Z.
The TDR was designed to provide agile handling and quick acceleration both on and off the road, and power delivery was modified to suit its intended use . The special upswept expansion chambers, unique to the TDR, part of this; as well as aiding ground clearance. The bike was originally released in a 250cc format, but a 240cc derivative was also produced exclusively for the French market.[1]
