In 1985 the ATC250R was updated with a 246cc liquid cooled engine, and 6-speed transmission. While the engine design remained similar, the Fuel delivery was increased from the previous 27 mm, to a 30 mm round-slide carburetor The 1983 ATC250R incorporated many improvements, introducing the Pro-Link suspension, folding foot pegs, a larger fuel tank, slightly longer travel suspension in front and rear. Both of these four-stroke models were sluggish and poorly suspended when compared to the 2-stroke ATC250R, which borrowed heavily from the Honda CR250R motocross line. While ATC racing was in its infancy, racers had to rely on Honda's ATC110 and ATC185 models on the racetrack. The introduction of the 1981 ATC250R marked a milestone in off-road history, as it was the first two-stroke ATC designed specifically for racing. Dual disc brakes were used on all model years, with the exception of the 1981, which used a front disc and a rear drum. All model years also used a gear-driven counter-balancer to reduce engine vibration.
1981–1982 models offered 6.7 inches of front suspension travel and 4.3 inches in the rear, 1983–1984 offered 8.7 inches in front and 8.1 inches rear, while post-1985 Models allowed 9.8 inches of travel. All model years were fully suspended and adjustable, using air-assisted front forks and a single, remote reservoir gas-charged rear shock.
Cited as the first high performance ATC introduced, production began with an air-cooled, 248 cc single-cylinder two-stroke engine, but would see a liquid-cooled, 246 cc engine by 1985.
The ATC250R is a high-performance, three-wheeled ATV produced by Honda from 1981 to 1986.
