Out of the Big Red series, the ATC250R was the only vehicle manufactured from 1981 to 1987. The 3rd generation ATC250R (1985 Big Red 250R) saw further enhancements in the powertrain, fuel delivery, and engine displacement. Wheel travel gradually increased across all three generations of the vehicle from 6.7/4.3 inches in 1981 to 9.8 inches in 1987. Among them were a gear-driven counter-balancer that reduced engine vibration, 30-mm round-slide carburetor, dual disc brakes for stopping power, adjustable, air-assisted front forks, and a single, fully suspended gas-charged rear shock.

Many of the improvements incorporated into the ATC250R were evident in the 2nd generation ATC250R (1983 Big Red 250R). It was not until the mid-1980s that Honda diversified its product line to include utility-type machines for industrial and agricultural use.

Together with the Big Red 250 and 250ES, the ATC250R was considered the holy grail of racing, created for recreation and competition. These attributes were not commonplace on other ATCs at the time. This racing machine introduced the market to a 248-/246-cc liquid-cooled powerplant, folding footpegs, and five and six-speed transmission options. The Honda ATC250R was eighth in the line of all-terrain cycles released by Honda since the ground-breaking US90 made its debut in 1970.

The Honda ATC250R had so much more to offer other than solidifying the presence of ATCs on the racetracks. Featuring Pro-Link suspension, an Enduro-Harley Davidson front aesthetic, and a 70 mph top speed, the ATC250R was tough and fast. The Honda ATC250R (or Big Red 250R) launched in 1981 and was the first to strengthen the foothold of ATCs in racing.

It was the perfect racing prototype created in such an inopportune time – only half-resurrected by the TRX250R, its four-wheeled successor that inherited its suspension and engine design.

It is completetly stock other than it has been bored. I cleaned the contacts on the distributor and checked the air filter, both are clean. The tank of gas that is in it was mixed by the previous owner, who owns several of these bikes, so I'm pretty sure the mixture ratio is correct. I took off the carb bowl and it was absolutely spotless and I changed the spark plug in case it was fouled. The problem is when you get on it about halfway through the rpm range, right where the powerband usually kicks in on a 2-stroke, it starts cutting out like it has a governor or a rev-limiter. I starts first or second kick every time and runs perfect at low rpms. I recently acquired a 1984 Honda ATC 250R three wheeler.
