The Honda CB250RS was a motorcycle part of the CB series in Honda's range designed for road use and powered by a 250cc four-stroke air-cooled upgraded version of the engine used by the earlier XL250S trail bike.
In 1982, the Japanese motorcycle manufacturer released the Honda CB250RS, which was known for its slim figure and nimble handling, with a dry weight of only 128 kg (282 lbs) and an engine fitted with counterbalancers that reduced vibrations and allowed the bike to carry a lighter frame.
The engine was used as a stressed member of the chassis, which reduced the overall weight and featured a kick-starter with an automatic decompression lever, while later, Deluxe models were fitted with an electric starter and different color schemes.
Standard features packed on the bike included a chromed, short dual exhaust system, analog instrument dials, a one-piece dual seat, a black-finished steel frame, a square headlight, a wide handlebar, and wire-spoked wheels.
In the performance department, the 1982 Honda CB250RS had at its core a 249 cc four-stroke single-cylinder air-cooled engine that delivered an output power of 26 hp with maximum strength at 8,500 rpm and 13 Nm (9 lb-ft) of torque available at 8,000 rpm.
Responsible for handling and safety was a telescopic fork on the front and dual shock absorbers with preload adjustability on the rear, while the braking performance was handled by a 250 mm disc with a hydraulic caliper on the front wheel and a 140 mm drum braking unit on the rear wheel.
