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.

The first iteration of the ATC125M (The Horizontal ATC125M) was an evolutionary advancement of the original US90 ATC released in 1970, the fourth revision of said cycle. It featured a 124cc Horizontal engine attached to a 4-Speed dual-range transmission to a chain final drive. The ATC125M added an electric starter, the first on a Horizontal-engine equipped Honda ATC, but continued to have drum brake.
