The Yamaha DT 125 was a motorcycle manufactured by Yamaha from 1974 until 2008. The bike saw the first sunshine in 1974 and was named DT 125A. The last sunset was seen on American grounds in 1981 as the DT 125H.

Suppose anybody wonders what DT stands for, well. In that case, it indicates a two-stroke, off-road motorcycle with features such as a raised exhaust system, a cross-member handlebar, universal tires, and enough ground clearance for an off-road enduro motorcycle.

Over its lifetime, the bike received numerous modifications, including the introduction of a single shock absorber on the rear in 1977, named by the maker as a Mono-Cross system.

In 1977, the Japanese motorcycle manufacturer launched the Yamaha DT 125, an entry-level, road-legal, and off-road wordy motorcycle capable of running on paved roads and unpaved trails.

The bike was fitted with standard features, such as wire-spoke wheels, off-road tires, a single exhaust system mounted high on the left side, a one-piece dual seat, a high-mounted front fender, and a round headlight up front.

The bike's suspension system comprised a telescopic fork on the front and a new single Mono-Cross shock absorber on the rear, providing optimum handling capabilities.

As for the power figures, the 1977 Yamaha DT 125 had installed a 123cc two-stroke single-cylinder air-cooled engine underneath its small fuel tank, boasting only 13 hp with a peak force at 7,000 rpm and 10 Nm (7 lb-ft) torque at 6,500 rpm.
