“The thinking man’s motorcycle.” That was Cycle magazine’s take on Honda’s half-liter four, the Honda CB500 Four. Smaller and lighter than its famous big brother, the trend-setting Honda CB750 Four, the new for 1971 Honda CB500 Four took all the 750’s fine attributes and focused them into a smaller, lighter bike that in many ways was better than its much-lauded forbearer.
Not that the 750 had many detractors. In its day, it was the undisputed king of big-bore bikes and was responsible for launching the Superbike category. Four cylinders, four pipes, electric start, no-fuss electrics and an imposing presence gave the CB750 Four a lead in the market that other manufacturers could only hope to match. But for all the good things the 750 was, it was one heavy machine. Tipping the scales at roughly 500 pounds all in, the 750 required a willing rider to wring the best from it. Ridden at five-tenths, it was serene, but at anything approaching attitude its slow steering, high center of gravity and ample weight combined to make it a bit of a handful.
Those issues disappeared with the Honda CB500 Four. Handling of the new “little” four was excellent, aided in no small part by an almost 80-pound advantage over the CB750 Four, the 500 weighing at a comparatively svelte 420 pounds. Additionally, the 500’s engine was significantly shorter than its big brother, thanks to its smaller displacement and over-square design (larger bore than stroke), which kept cylinder height down, giving a lower center of gravity. Where the 750 was often faulted for vague handling, the CB500 Four was lauded for being stable and predictable if perhaps still a bit slow-steering. Part of that stability was due to the 500’s frame, which drew heavily from the 750 but featured extra gusseting to tame frame flex. Honda’s excellent front forks helped keep the front wheel on the ground, but the rear shocks drew complaints, with one tester calling them “the weakest point about the 500,” noting the shocks on a test bike had failed after just 1,000 miles.
