Honda CBX

Engine characteristics

Honda had produced a Honda RC series six-cylinder race bike in the mid-1960s, but the CBX was Honda's first production 6 cylinder road bike. The CBX's advanced DOHC 24-valve inline six-cylinder engine was its outstanding feature; but in other respects the bike was conventional, having telescopic forks, a tubular frame, twin rear shocks and straight handlebars.
Although bulky, the engine was wide only at the top. The width across the crankshaft was relatively narrow as the CBX had a stacked engine accessory arrangement, whereby the alternator and ignition items were positioned behind the cylinder block. This arrangement produced an acceptable engine width low down and moved critical items out of harm's way in the event of grounding.
Journalist L. J. K. Setright wrote of the CBX's width: "Don't tell me that its engine is too wide: It is no wider than the legs of a rider, so it adds nothing to the frontal area, and personally I would rather have my legs shielded by a cylinder apiece than exposed to every blow ...

Sport touring model

In 1981, Honda repositioned the CBX into the sport touring category with the CBX-B, detuning the engine and adding Pro-Link monoshock rear suspension, air-adjustable 39 mm front forks, a fairing and panniers with a stronger frame to support these additions. The CBX was given beefier dual ventilated front brake discs to help bring to a stop the bike's increased weight. The 1982 model CBX-C model differed little from the 1981 model, having only some changes to paint and trim.
