The 1970s: The World's First ATC

Officially introduced to America in 1970, the US 90 sent its 7 horsepower through a dual-range four-speed gearbox with automatic clutch, and sold for $595. It was renamed the ATC90 later that year as Honda trademarked the ATC name. Three models carried that Honda ATC monogram through the 1970s. The ATC70 gave younger riders a scaled-down version of the fat-tire experience. And by the end of the decade, requests for more power turned the original ATC90 into the ATC110 in 1979. The ATC was as evolutionary as it was revolutionary from the beginning.

Good as the original fat tires were on snow and sand, they were vulnerable to punctures from things such as stubble from harvested crops. The fact that those original tires weren't repairable compounded the problem, so a fabric carcass was added, and steel hubs replaced the first hubless wheel design in 1975. Tougher, color-impregnated plastic fenders were added in 1975 as well.
Though it was primarily a recreational vehicle through the '70s, farmers were beginning to see the ATC as a tool to make their lives easier. Engineers followed their machines into the field, gathering data to guide the machine's natural adaptation to a rapidly growing market. The ATC was as capable at labor as at leisure, and America was catching on.
