The Yamaha DT250 was preceded by the 1968 DT-1. The DT250 began production in 1971 and was produced through 1982. Other models produced in the DT250 group were the DT250F and DT250MX. [2] The DT250 was released three years earlier than the Yamaha DT125. The DT250 was one of the leading dual-sport machines in the 1970s. [3]
The stock bike made 39 bhp (29 kW) (32 bhp (24 kW) at the back wheel) at 7500 rpm [1] – very fast for the time. A contemporary of the RD is the Kawasaki H2 750cc Triple that produced 74 hp. The 350 evolved into the more refined and cleaner running RD400C in 1976, the "D" and "E" in 77–78 and the final model, the white 1979 RD400F.
