A Brief History From The 1970 Yamaha 250 Mx

Yamaha's DT 250 MX bike was a world-class motocross machine, and was available to the consumer market from 1968 through 1982.


Performance


The Yamaha DT 250 engine featured a displacement of 246 cubic-centimeters, a size-able motor for a two-stroke, Reed-valve design. The DT 250 used an air-cooling system, giving it a longer operational time than a wet-cooling system. Power output was rated and advertised with 22.84 horsepower at 7,000 rpm and 12.9 foot-pounds of torque at 6,500 rpm. A five-speed, manual transmission was standard for gear shifting.


Wheels


The front and rear wheels were both aluminum alloy. The front wheels were wrapped with 21-inch by 3-inch tires, while the rear wheels featured 18-inch by 4-inch tires. The front and rear wheels came from the factory with expanding brakes, which operate outward against the inside of the drum of the brake.


Body


Wet weight of this bike was about 284 pounds, which included all fluids and a full tank of fuel. Fuel capacity was 2.38 gallons. This bike was available in red/black and orange/black.
