Segment: Naked / Road
Production years: 1982, 1983
In 1983, the Japanese motorcycle manufacturer launched the Honda CB250RS, a naked machine part of the CB series manufactured until the mid-80s. The bike offered decent power and agility and was mainly designed as an entry-level bike for younger and less-experienced riders.
The bike provided a slim figure and agile 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 an upgraded version of the one used on the earlier XL250S trail bike, with a kick starter with an automatic decompression lever and used as a stressed member of the chassis, which reduced the overall weight.
In addition, the model packed 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.
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.
In the muscle department, the 1983 Honda CB250RS took its nerves from 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.
