Vehicle Information
Yamaha DT125 Motorcycle - Dual-Sport (1974-1981)
The Yamaha DT125, a versatile dual-purpose enduro motorcycle, was produced from 1974 to 1981. Throughout these years, it consistently featured a 123cc air-cooled, two-stroke, single-cylinder engine. This model was renowned for its reliability and adaptability, making it a popular choice for both on-road and off-road adventures. Significant updates occurred during its production run. In 1977, the DT125MX trim introduced Yamaha's innovative Mono-Cross single-shock rear suspension, greatly enhancing off-road performance. The 1978 DT125E variant further refined the lineup by adding an electric starting system and increasing suspension travel, alongside a new leading axle front fork design. These changes marked distinct evolutions in the DT125's platform. FAQ:
