[2] The CB500 Four is styled like the CB750, but smaller and lighter, with a claimed 50 bhp (37 kW) output and a top speed of 115 mph (185 km/h).

Reviewing the 1972 show models, UK monthly magazine Motorcycle Mechanics described the CB500 as "one of the 'show stealers'.

Four cylinders, in-line across the frame, four carburettors and single overhead camshaft motor, coupled to a five-speed gearbox give this 500 cc machine the performance of a 650 twin cylinder bike.

Bill Smith won the 1973 500 cc TT Production race (four laps) riding one, 8.2 seconds ahead of second place Stan Woods mounted on a Suzuki T500 two-stroke, twin.
