Production years: 1983, 1984
The Honda CB250RS, released by the Japanese motorcycle manufacturer in 1984, was an agile entry-level machine part of the CB series that offered great maneuverability and fuel efficiency, mainly designed for younger and less-experienced riders.
The bike packed an upgraded version of the engine used by the earlier XL250S trail bike and mounted as a stressed member of the chassis with counterbalancers that reduced vibrations and allowed the bike to carry a lighter frame.
For suspension, the bike packed a telescopic fork on the front and dual shock absorbers with preload adjustability on the rear, while the stopping power 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.
As for the power figures, the 1984 Honda CB250RS was set in motion by a 249 cc four-stroke single-cylinder air-cooled engine fed by a Keihin carburetor and 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.
The engine generated decent power and featured dual exhaust pipes for each port, coupled to a five-speed manual transmission that pushed the bike to a top speed of 136 kph (84 mph).
In addition, the bike came equipped from the factory with standard features, such as 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.
