The Honda ATC250R all terrain cycle revolutionized the off-road industry. This three wheeled all terrain cycle was produced by Honda Motor Corporation from 1981 through 1986.
It was designed with the intention of being a racing three wheeler. The ATC250R did the racing thing quite well. As a matter of fact, this all terrain cycle improved on excellence in each of its years of existence.
The all terrain cycle had been a popular vehicle in previous years. but the 1981 ATC250R was the first to be released with a two stroke engine. All previous Honda ATC's were equipped with four stroke motors.
The 1981 ATC250R was essentially a three wheeler with a CR250 engine. It featured full suspension which was considered to be leading edge at the time. The engine was an air-cooled single cylinder.
Shortcomings include the rear brakes on this trike. Honda decided to use drum brakes in the rear which was an unfortunate decision by their engineers. In 1982 Honda corrected the rear brakes with the addition of disc braking at the rear wheels of the machine. Otherwise the ATC remained mostly the same.
1983 and Up
1983 was considered to be the start of what ATC enthusiasts call generation two. The 1983 ATC250R was ultimately equipped with Honda's infamous pro-link suspension. The pro-link suspension on this ATC greatly improved the wheel to ground connection when experiencing a bounce or bump.
Honda's innovative suspension greatly improved ride quality. There were also minor engine improvements. These improvements carried through the the 1984 model year as well.
The 1985 and 1986 model years are what legends are made of. Honda redesigned the frame, improved on the suspension once again, and added the liquid cooled powerplant. Honda's new 250R engine produced more torque than previous engines thanks to a higher compression ratio.
Legend would have it that the combination of a six speed transmission and the 246 cc engine pushed these ATC's to 70+mph, a tribute to marvelous engineering. The 1986 model year was the last production 250R, it was mostly unchanged from the 1985 model. Honda discontinued their ATC lineup as a result of legal action banning the sale of three wheelers.
