Iconic. Legendary. Zero nonsense. Is this the perfect CB750 K6? What do you think, guys? Comment below👇
Long before superbikes became a numbers war of wings, electronics and improbable horsepower, Honda rewrote the motorcycle rulebook with the CB750 Four. Introduced in 1969, its 736cc air-cooled SOHC transverse inline-four, electric start and hydraulically operated front disc brake arrived like technology smuggled in from the future, helping establish both the superbike idea and the template that would later be called the Universal Japanese Motorcycle. By the 1976 K6, the formula had been thoroughly polished: around 67 hp, four Keihin carburettors operated by Honda’s twin-cable throttle arrangement, a five-speed gearbox and that gloriously extravagant four-into-four exhaust system. Candy Antares Red gave the K6 one of the era’s great Honda liveries, while underneath sat another piece of clever engineering the CB750’s dry-sump lubrication system. Instead of keeping its entire oil supply beneath the crankshaft like a conventional wet-sump engine, Honda used a separate reservoir tucked behind the right-hand side cover; the cap emerging through the cover doubles as the dipstick and filling point. It’s an unusually visible reminder that the CB750 wasn’t merely handsome it was properly engineered.
This K6 from Japanese builder Librebike JP takes that landmark machine and strips away some of the grand-tourer politeness without erasing its seventies DNA. The deep red tank and period Honda graphics remain the visual centrepiece, but the stance is tighter and more purposeful: lower street-style handlebars, a slim ribbed saddle, abbreviated rear end, exposed twin shocks and chunky tyres wrapped around classic wire-spoked wheels give it the attitude of a vintage Tokyo backstreet bruiser. Crucially, the magnificent finned four-cylinder engine remains on display rather than disappearing beneath modern bodywork, while the pared-back detailing lets all that polished alloy, chrome and mechanical architecture do the decorating. The result isn’t a CB750 desperately pretending to be contemporary; it’s the opposite a carefully sharpened version of the motorcycle that helped define what a modern big bike was in the first place. Nearly six decades later, Honda’s original superbike still looks like it has somewhere important to be.
