The Honda ATC125M was a three-wheeled All Terrain Cycle released in 1984, and received a major revision in 1986. The model was sold through 1987, when Honda voluntarily discontinued sales of ATC's. The first iteration can trace its development back to Honda's first ATC, the Honda US90, released in 1970, while the second iteration borrowed heavily from the ATC200 line.
