Development of ATVs

ATVs (all-terrain vehicles) were first developed during the 1950s. The earliest models had six wheels instead of the four that riders are now familiar with. Honda was the first company to make the 3-wheel ATV in 1970. These were famously displayed in the James Bond film, 'Diamonds Are Forever.' Originally called the US90, the ATV was purely for fun, made with very large balloon tires instead of the mechanical suspension and smaller tires eventually introduced in the early 1980s.
