The Yamaha DT was a series of motorcycles and mopeds manufactured by Yamaha from 1968 to 1985. The DT series was created in the 1960s when the American motorcycle market was down and comprised models with engine displacements ranging between 40 to 400cc.

In 1968, the Japanese motorcycle manufacturer launched the Yamaha DT-1, their first model, which had great success and quickly sold through its 12,000 production run. The DT-1 model defined a new market for motorcycles.

It was a dual-sports motorcycle developed to run on off-road trails, with its block-pattern tires, decent ground clearance, and cutting-edge design for its period. It was driven by a 250cc one-cylinder engine based on a motocross design.

The bike was built around a steel frame with a telescopic fork on the front and dual side-mounted shock absorbers on the rear, delivering excellent suspension performance and handling capabilities.

The braking performance was handled by a front and rear drum braking unit, providing optimum stopping power.

In the visual department, the bike packed standard features, such as a small, round headlight on the front, a single seat, a high-mounted exhaust system, steel fenders, and lightweight wire-spoke wheels with off-road tires.

As for the power figures, the 1968 Yamaha DT-1 had installed a 250cc two-stroke air-cooled single-cylinder engine underneath its small fuel tank, delivering 21 hp at 6,000 rpm.
