The engine’s overarching attribute is its easygoing nature. Because of the single balance shaft and two rubber engine mounts, it’s a smooth operator, completely lacking the classic inline-four tingle that made the CB750 famous—or infamous, if your extremities are still a bit numb. Throttle response from the electronic fuel injection is creamy, even without secondary butterflies to smooth power delivery. Torque ramps up nicely by 1500 rpm and seems to peak early. Honda says the torque peak of 68.6 lb.-ft. occurs at just 5000 rpm (with a max of 88.5 horsepower at 7500 rpm), and the bike feels just that way. From the torque peak to the 8500-rpm redline, anticipate diminishing returns. Sure, you can wring it out, but the engine loves to loaf, turning slightly buzzy above 6500 rpm as a way of saying, “Slow down, son. You’re not 20 any more.” The wide-ratio transmission allows you to stay in the comfort zone to highway speeds—who needs sixth gear? Accompanying your endeavors is a dignified whoosh from the airbox and barely a sizzle from the CB400F-esque exhaust.
