The '''Honda CB-1''' is a small, light [[naked bike|naked]] sports motorcycle with a {{Convert|399|cc|adj=on}} [[Inline-four engine|straight-four]] engine, carrying the model code NC27. In contrast to other models of the [[Honda CB series]], the name is written with a hyphen. In some countries it was marketed as Honda CB400F. 

The bike was first introduced in 1989 and continued through 1990. Originally developed for the Japanese market, the CB-1 was also available in the United States and Canada. Called a "great motorcycle that never found an audience" and "victims of a difficult market" by ''Cycle World'', the final model year 1990 CB-1s available as leftover stock were offered in 1992 at a $600 discount, for $3700 in the US, which in current money would be ${{Formatnum:{{Inflation|US|3700|1992}}}} accounting for [[inflation]].<ref name=CycleWorldFeb1992>{{Citation |title=Best Buys; The affordable alternative to sticker shock |first= Matthew |last= Miles |magazine=Cycle World |location= New York |date= Apr 1989 |volume= 28 |issue= 4 |pages= 44–47 }}</ref>

The CB-1 engine is similar to the early NC23 models [[Honda CBR400RR|CBR400RR]],<ref name=CycleWorldApril1989/> with changes to the port lengths and angles as well as smaller valves and lower compression ratio; changes in the primary and secondary gear ratios reduced the {{Convert|60|mph|abbr=on}} first gear down to around {{Convert|30|mph|abbr=on}}, making the slightly less powerful CB-1 feel much quicker from a standstill than its sportier sibling, All engines derived from the NC23 block carry the NC23 ID code in the engine number; this includes the NC27, 23, 29, 31 etc., including the [[VTEC]] models with chain driven cams. Like many of its stablemates, the CB-1 has straight gear-driven dual camshafts with self-silencing gears to reduce whine.

''Cycle World'' measured the time to cover a {{Convert|1/4|mi}} as 13.17 seconds with a final speed of {{Convert|99.16|mph}} and the top speed as {{Convert|118|mph}}<ref name=CycleWorldApril1989/> Braking distance from {{Convert|60|to|0|mph}} was {{Convert|124|ft}}.<ref name=CycleWorldApril1989/> &mdash; saying the bike was "a reincarnation of the standard motorcycle ... the sort of bike everyone rode before sporting riders went replica racer crazy".<ref name=CycleWorldApril1989>"{{Citation |title= Honda CB-1; A new standard with the soul of a suburbanite and the heart of a tiger |magazine=Cycle World |location= New York |date= Apr 1989 |volume= 28 |issue= 4 |pages= 44–47 }}</ref>
