The Yamaha DT-1 became the first mass-produced dual-sport motorcycle when it was launched in 1968.
Yamaha designed the DT-1 to work both on paved roads and on unpaved trails. Its 250 cc two-stroke single-cylinder engine, relatively light weight and practical chassis made it approachable for everyday riders while retaining genuine off-road ability.
Earlier motorcycles could be ridden on both roads and trails, but the DT-1 is widely credited with creating the modern factory dual-sport category. Yamaha marketed it in the United States during a period when recreational off-road riding was rapidly expanding.
The DT-1 also influenced the later XT and DT families. It is sometimes confused with later four-stroke trail motorcycles such as Honda’s XL series, but those arrived after Yamaha had established the dual-sport formula with the DT-1.
