Honda Sport ATCs, produced until 1987, were built specifically for performance, and designed for use in racing, or for aggressive trail riding. The machines lacked luggage racks and other utilitarian features, commonplace on most other ATCs or ATVs.
In 1970, Honda created the three-wheeled “All Terrain Cycle” market nearly single-handedly with the release of the Honda US90.[1] As the popularity of ATCs exploded in the late seventies, Honda began to diversify their line. Originally catering to winter activity, campers, hunters and weekend Recreational riders that ATCs were envisioned for, their research showed there was a market for utility-focused machines for commercial and agricultural use, and dedicated sport models intended for leisure and competition use.
This led to the creation of the ATC250R,[2] a 2-stroke racing ATC based on the CR250 motocross line in 1981 and 3 more Sport ATCs, using 4-stroke engines.[3] The ATC250R remains a popular model for collectors due to its high-performance 2-stroke engines and racing heritage; and the 4-stroke “X” ATCs continue to be popular trail machines.

The ATC250SX was introduced alongside the ATC350X in 1985, and available for three model years. Decidedly more a trail machine than a racer, this ATC was equipped with a 246cc 4-Stroke air-cooled OHV engine, with 5-speed auto-clutch transmission and shaft final drive. Stoppage was handled by front and rear drum brakes, and it featured a reverse gear, unique among Honda Sport ATCs. This added to the weight, of nearly 50lbs more than similar machines.[5]
