The Honda CB -1 ( NC27 code ) is a lightweight and undisguised Sports motorcycle with a liquid-cooled 4- stroke, four- cylinder engine with a displacement of 399 cm3 and a power of 42 kW (57 hp). There were two series, 1989 and 1990, which differ only marginally. In the last year of construction, the model for the Japanese market has been slightly revised, so it got for example a Edelstahlauspuffkrümmer.
The engine of the CB- 1 is largely identical to that of the Honda CBR 400RR "Baby Blade", the early model years of the CB- 1, therefore, support the engine code NC23E that corresponds to the code of the CBR. The Engine Code of the later models begins with NC27E. The two camshafts are driven by gears. The transmission has six gears, the final drive ratio 15 / 41st The chassis is made of 41 mm telescopic forks up front with no adjustment facility and a rectangular tube with Monoshock rear. The frame is a tubular steel bridge frame with welded rear frame. The three-spoke cast wheels have a diameter of 17 inches. At the front and rear, there is a respective disc brake. The tank capacity is 11.5 liters, the dry weight of 183 kg. Officially, the CB-1 was sold in the U.S. and Canada. For California, there was a special version with a secondary air system.
The about 1800 sold in Germany CB-1 were original California models, that is, they had the secondary air system, but were throttled for Germany through another exhaust to 50 hp. A few however, have been sold with speedometer stickers on the Honda dealer. These were versions that were on the market worldwide. Otherwise, mostly "gray" CB-1 sold since the model was not officially offered for sale in Germany in Germany.
