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 $7,145 accounting for inflation.[2]

The CB-1 engine is similar to the early NC23 models CBR400RR,[1] 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 60 mph (97 km/h) first gear down to around 30 mph (48 km/h), 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 1⁄4 mile (0.40 km) as 13.17 seconds with a final speed of 99.16 miles per hour (159.58 km/h) and the top speed as 118 miles per hour (190 km/h)[1] Braking distance from 60 to 0 miles per hour (97 to 0 km/h) was 124 feet (38 m).[1] — saying the bike was "a reincarnation of the standard motorcycle ... the sort of bike everyone rode before sporting riders went replica racer crazy".[1]

Die Honda CB-1 (Code NC27) ist ein unverkleidetes Motorrad des japanischen Herstellers Honda. Es gab zwei Baureihen, 1989 und 1990, die sich nur marginal unterscheiden. Im letzten Baujahr wurde das Modell für den japanischen Markt noch leicht überarbeitet, so bekam es zum Beispiel einen Edelstahlauspuffkrümmer.
