The Yamaha DT175 was a 125cc, 2-stroke, dual-purpose motorcycle manufactured by Yamaha from 1974 through 1988 in the US. Some derivatives are still sold in other markets to this day. The model designation DT indicates that it is a 2-stoke off-road styled motorcycle, it had a raised exhaust, handlebars with cross members, universal tires, and adequate ground clearance for an off-road enduro motorcycle or trail motorcycle. The USA received the last DT125H in 1981.

The DT125 had a raised rear and front fender, raised exhaust, handlebars with cross members, universal tires, and adequate ground clearance for an off-road-enduro motorcycle or trail motorcycle.

When first launched the DT125 had a single cylinder, air-cooled, 2-stroke engine, a cradle style tubular steel frame, conventional telescopic front forks and dual shock swingarm rear suspension, and drum brakes front and rear. Over the years the model received numerous updates and restyles, the dates and specifications of which vary between different markets. Notable changes include the appearance of a single shock absorber rear swingarm in 1977, which Yamaha referred to as Mono-cross, or MX for short, a feature that appeared on many of Yamaha's other small and medium sized motorcycles at a similar time. In 1983 the DT125 received a major restyle and gained a liquid cooled engine to become the DT125LC. In 1985 the electrics were upgraded to 12v, the front brake drum was changed to a disc, and rising rate rear suspension was fitted with the introduction of the DT125LC mk3. Another restyle for 1987 gave us the DT125R, the most noticeable specification change from it's predecessor being the swap to a rear disc brake.
