HONDA CB900 Custom (1979-1980) Specs, Performance & Photos

The Honda CB900 Custom was a cruiser motorcycle part of the Cb series in Honda's range, manufactured from 1980 to 1982 primarily for the American market, while in 1983, it was succeeded by the CB1000C.

The CB900 Custom was derived from the DOHC CB750K and was closely related to the CB900F and the CB1100F, which was built only in 1983 and were both derived from the CB750 line. The final drive and the rear suspension assembly came from the GL and CX series of touring motorcycles at the time.

Also, the frame was derived from the European CB900F and extended five cm (2 inches) to accommodate 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.

For suspension, the bike packed a 37 mm air-assisted telescopic fork on the front and dual air-assisted shock absorbers on the rear, while the stopping power was handled by two 280 mm discs with two-piston calipers on the front wheel and one 297 mm disc with a single-piston caliper on the rear wheel.

In the performance department, the 1980 Honda CB900 Custom had its soul brought to life by 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.
