Not only did it boast a potent overhead camshaft engine, the big four also outpaced everything else in its class by offering a disc front brake, a five-speed gearbox and stunning looks as well as usual Honda features like electric starting and a superb finish. Able to top 120mph whilst still being docile at city speeds, the CB750 delivered its power more smoothly than any big sportster before it. The bike on display has had one owner since new and has never been ridden.
