YAMAHA DT 125 (1974-1975) Specs, Performance & Photos

The Yamaha DT 125 was an enduro motorcycle manufactured by Yamaha from 1974 until 2008. The bike was first released in 1974 as the DT 125A and was last seen in the American market as the DT 125H in 1981.

The DT designation indicated a two-stroke, off-road-styled motorcycle with a raised exhaust system, a cross-member handlebar, universal tires, and enough ground clearance for an off-road enduro motorcycle.

When first released, the bike packed a single-cylinder, two-stroke air-cooled engine, a cradle-style tubular steel frame, a traditional telescopic fork on the front, twin shocks on the rear, and drum braking units both front and rear.

Over its production period, the bike gained several upgrades and modifications, including the introduction of a single shock absorber on the rear in 1977, which the maker referred to as a Mono-Cross system.

Other modifications were represented by a significant restyle and a liquid-cooled engine in 1982, upgraded electronics and a brake disc on the front in 1984, and another restyle in 1987 alongside a rear brake disc.

In 1974, the Japanese motorcycle manufacturer launched the Yamaha DT 125, a motorcycle powered by a 123cc two-stroke single-cylinder liquid-cooled engine fed by a carburetor. The engine delivered an output power of 14 hp with a peak force at 7,500 rpm and 14 Nm (10 lb-ft) torque at 7,000 rpm.
