History

Yamaha produced the enduro DT1 250 in 1968. The motorcycle was embraced and Yamaha learned that, in America riders were interested in motorcycles which could operate off road, and on road. Yamaha experimented with larger displacement and in 1975 they created the DT400B. The DT400B did not initially sell well, and Yamaha reduced the price. The 2 stroke engine was not ideal and by 1979 the DT400B was discontinued.[3]
