In the late 1960s, Mr. Takeuchi of Honda Motor Company developed a three-wheel gasoline powered vehicle equipped with low-pressure tires. Primarily intended for utility and snow operation purposes, this vehicle was released for production in 1970. It was called the US 90 All-Terrain Cycle (ATC), a name that reflected both the general usage and engine size. This vehicle effectively launched what was to be the beginning of the All-Terrain Vehicle (ATV) era in the U.S.A.Soon after ATVs hit the market, vehicle upsets, accidents, and injuries began to occur. The three-wheel design geometry had resulted in a vehicle that would pitch/roll upset easily at very low speeds. In the early 1980s, the ATV industry evolved substantially with the introduction of four-wheel all-terrain vehicles. This new vehicle design marked the beginning of the end for the three wheel all-terrain vehicles.
