Vehicle Information
Honda ATC250 ATV (1981-1987)
The Honda ATC250R, produced from 1981 to 1987, was a high-performance, three-wheeled ATV renowned for its racing capabilities. This iconic model featured a powerful two-stroke, single-cylinder engine, evolving from air-cooled (248cc/247cc) to liquid-cooled (246cc) configurations during its production run. It was exclusively offered as the "R" model, signifying its dedicated racing trim, without separate base or deluxe versions. Throughout its production, the ATC250R underwent significant generational updates. The first generation (1981-1982) featured an air-cooled 248cc engine and a 5-speed transmission. The second generation (1983-1984) maintained an air-cooled 247cc engine but introduced Honda's Pro-Link suspension system, greatly enhancing travel. A major shift occurred in the third generation (1985-1987) with the introduction of a liquid-cooled 246cc engine and an upgraded 6-speed transmission, alongside further suspension and frame improvements. The 1987 models, identical to 1986, were primarily available in Canada and Europe. FAQ:
