Before the era of four-wheeled dominance, a quirky and charismatic three-wheeler captured the hearts of adventure seekers and laid the foundation for the entire ATV industry.
That machine was the Honda US90, later known as the ATC90.
As a passionate off-road enthusiast, I have a deep appreciation for the pioneers of our sport, and the US90/ATC90 holds a special place in history.
In this article, we’ll take a deep dive into the story of this iconic three-wheeler, exploring its innovative design,
its impact on the market, and why it remains a beloved classic to this day.
Join me as we pay tribute to the legendary Honda US90/ATC90, the little three-wheeler that started a revolution.
A New Concept in Off-Road Fun
In 1970, Honda introduced a vehicle that would forever change the landscape of recreational off-roading: the US90. [1]
At a time when off-road options were limited, the US90 offered a new and accessible way to explore the great outdoors.
Its most striking feature was its three-wheel design, with large, low-pressure “balloon” tires that gave it a unique and unforgettable appearance.
The Birth of the All-Terrain Cycle
The US90 was more than just a novelty; it was a well-engineered machine designed for fun and adventure.
The official name, All-Terrain Cycle (ATC), perfectly described its purpose.
It was a vehicle that could go almost anywhere, from sandy beaches to snowy trails.
The simple, air-cooled 89cc four-stroke engine was reliable and easy to maintain, making it the perfect entry-level machine for aspiring off-roaders.
The Evolution to the ATC90
As the popularity of the US90 grew, Honda continued to refine and improve the design.
In 1974, the US90 was officially renamed the ATC90, solidifying its identity as the original All-Terrain Cycle.
The ATC90 retained the core characteristics of the US90 but featured several improvements, including a more robust frame and a more efficient engine.
A Legacy of Fun and Adventure
The ATC90’s success was a testament to its simple yet effective design.
It was a machine that was easy to ride, affordable to own, and incredibly fun.
It introduced a whole new generation of riders to the joys of off-roading and created a market that would eventually explode in popularity.
The ATC90’s legacy is not just in the machines it inspired but in the countless memories it created for families and friends who discovered the thrill of off-road adventure together.
The End of an Era and a Lasting Impact
Despite its immense popularity, the era of the three-wheeler eventually came to an end.
Concerns over safety and the growing popularity of four-wheeled ATVs led to a decline in the production of three-wheelers in the late 1980s.
However, the impact of the Honda US90/ATC90 on the off-road world is undeniable.
The Foundation for the Future
The US90/ATC90 proved that there was a massive market for personal off-road vehicles, paving the way for the development of the modern ATV.
It introduced key concepts like low-pressure tires and a simple, reliable design that are still relevant today.
The spirit of the US90/ATC90 lives on in every ATV that hits the trail,
a testament to its enduring legacy as a true pioneer of the off-road world.
Conclusion: A Timeless Classic
The Honda US90/ATC90 may be a relic of a bygone era,
but its significance in the history of off-roading cannot be overstated.
It was a machine that was ahead of its time,
a bold and innovative concept that captured the imagination of a generation.
The US90/ATC90 was more than just a three-wheeler; it was a symbol of freedom, fun, and adventure.
It’s a timeless classic that will forever be remembered as the little machine that started it all.
