Which motorcycle was the first production bike to use Honda’s six-cylinder CBX engine?

The story behind the answer

The Honda CBX1000 was the first production motorcycle to use Honda’s six-cylinder CBX engine.

Honda introduced the CBX in 1978 with a 1,047 cc, air-cooled, double-overhead-camshaft inline-six engine. Its closely spaced cylinders and six individual carburetors created a distinctive appearance and a high-revving exhaust note.

The CBX was conceived as a flagship performance motorcycle and produced roughly 105 horsepower in its original form, depending on market specification. Its engine was much wider than a four-cylinder design, but Honda packaged the alternator and other components behind the cylinders to reduce overall width.

Later CBX versions gained touring equipment, including a fairing and luggage, but the original naked model is the version most associated with the motorcycle’s dramatic six-cylinder layout.
