The Honda CB250N and CB400N Super Dream are motorcycles manufactured by the

CB750F and CB900F. It was a popular model for Honda with 70,000 bikes sold in the UK alone.[7]

Engine

The Super Dream was fitted with a

transmission and chain final drive.[8] Fuelling was provided by twin Keihin carburettors.[9]

CB250N

The CB250N Super Dream was a 249 cc (15.2 cu in) motorbike. It was a popular model in the United Kingdom due to the licensing laws at the time allowing learners to ride any motorbike with a capacity under 250cc.[10][11] The CB250N was the most popular selling bike in the UK with over 17000 bikes sold in 1980 alone.[10] Its popularity in the United Kingdom waned along with many in the 250cc class when in 1983, the maximum size of learner machines was reduced to 125 cc (7.6 cu in).

During its production run it had several variations from 1978 to 1986. The various designations were, CB250N (1978–1979), CB250NA (1980), CB250NB/NDB Deluxe (1981) and CB250NDC (1982–1985)[12] and CB250NDD (1983–1986).

CB400N

The CB400N Super Dream was very similar to the 250N variant. However, it differed from the 250N with its larger engine capacity, twin front brake discs and a halogen front head light.[6] The instrumentation had different markings for the rev counter and speedometer to reflect the higher top speed and lower RPM redline.[12]

The CB400N had several revisions during its production run. The launch model CB400N (1979–1980), CB400NA (1980–1981), CB400NB (1981–1983), CB400NC (1982–1985)[12] and CB400ND (1983–1986).
