Suzuki developed the first four-wheel all-terrain vehicle (ATV) in 1982, called the LT125D, according to the Specialty Vehicle Institute of America. Although Suzuki was the first company to hit the market with a four-wheel ATV, Honda had developed the backbone of the machine in 1970 and is accredited as inventor of the ATV; however the first model only used three wheels.
Suzuki's first four-wheel ATV featured a five-speed transmission and the ability to reverse as well as came equipped with an odometer, as stated by the Specialty Vehicle Institute of America. Shortly after, in 1984, Honda's first four-wheel design was released to the market. Both companies have continued to diversify and improve ATV models since.
