Yamaha DT175 Motorcycle - Dual-Sport (1974-1981)

The Yamaha DT175, produced from 1974 to 1981, was a highly popular air-cooled, two-stroke, single-cylinder enduro motorcycle. Renowned for its reliability and versatility, it featured a consistent 171 cc engine (66 x 50 mm bore/stroke) throughout its production run, delivering between 14 and 16.5 horsepower depending on the year. This model was primarily known as the DT175 or DT175 MX, without distinct trim levels, but rather continuous annual updates. While maintaining its core identity, the DT175 underwent several significant mid-cycle changes. The 1974 model was a redesign of its predecessor, introducing reed-valve induction and a 21-inch front wheel. A major update in 1977-1978 brought the revolutionary Monocross monoshock rear suspension, a restyled frame, and a redesigned engine, making the bike lighter. Further enhancements in 1979-1981 included cylinder and carburetor improvements, a square-tube swingarm, and an improved gearbox selector, evolving the model significantly over its lifespan.
