Segment: Custom/Cruiser
Production years: 1980, 1981
In 1981, the Japanese motorcycle manufacturer released the Honda CB900 Custom, a cruiser motorcycle manufactured from 1980 to 1982, especially for the American market, while in 1983, the bike was replaced by the Honda CB1000C.
The CB900 was derived from the CB750K and closely related to the CB900F and CB1100F models, both derived from the CB750 line. The final drive and the rear suspension assembly came from GL and CX touring machines available at the time.
The frame was also derived from the CB900F but came in a five cm (2-inches) longer package that accommodated the sub-transmission components. The sub-transmission packed a jackshaft that allowed the rider to select a high or low range for the five gears, effectively giving an overdrive sixth speed for cruising.
In addition, the CB900 Custom packed standard features, such as a four-into-four chromed exhaust system, a dual seat with a passenger grab handle, a pulled-back handlebar, a round headlight with a chromed ring, an analog instrument panel, a center stand, and cast aluminum wheels.
As for performance, the 1981 Honda CB900 Custom was fitted with a 901cc four-stroke four-cylinder air-cooled engine fed by four Keihin carburetors that helped delivered an output power of 95 hp with maximum strength at 9,000 rpm and 77 Nm (57 lb-ft) of torque available at 8,000 rpm.
With a dry weight of 277 kg (611 lbs) and set in motion by a five-speed manual transmission, the CB900 Custom reached a top speed of 217 kph (135 mph).
