Its siblings – the ATC 250SX, the Honda Big Red 350 or Honda ATC350X, and the Big Red 200 or ATC200 trims – enjoyed only half the air time than it did with consumers.Ī later version of the ATC250R, the Big Red ATC250ES, was sold outside of U.S. 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.

Read on and discover more about the specifications, improvements, and mod ideas surrounding Honda’s first high-performance all-terrain vehicle. Its durability, build quality, and performance made the wheeler appealing to the riding community and consumers in general.

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. The Honda ATC250R was the greatest high-performance three-wheeler ever produced by a big-name manufacturer. Disclosure: We may get commissions for purchases made through links in this post.
