CBX750F ナナハン.
The RC17 engine: a 747 cc air-cooled, double-overhead-cam inline four. It grew out of the CBX650 but got a stronger crank and crankcases, bigger valves worked by hydraulic tappets, and a bank of four 34 mm Keihin CV carbs. Torque peaks at 6.5 kg·m at 7,500 rpm, power at 9,500. The same engine came back in Honda's Seven Fifty (RC42) from 1992 to 2008.

CBX1000 六気筒.
Cycle World timed the first one at 11.64 seconds for the quarter mile at 117.95 mph, and it was the first bike they tested past 130 mph. The alternator and ignition sat behind the cylinders, so the engine was only two inches wider than a CB750's. Owners compare its top-end howl to a jet fighter or a Formula car.
