The seller has provided a very comprehensive walkaround video with a cold start at the end:
Honda had already established themselves as a premier manufacturer of small bikes in the US by the mid 60s thanks to their stellar reliability and ease of use – the “you meet the nicest people on a Honda” slogan didn’t hurt, either. But the biggest bike they made was the 450, and that wasn’t selling as well as Honda had hoped. A senior engineer named Yoshiro Harada toured the US in 1967 with the intent of getting dealers to shift more CB450s, but he soon learned that American riders were clamoring for more displacement. So he went back home and the Japanese firm started working on “The king of motorcycles.”
Honda introduced the world to the four-cylinder CB750 at the Tokyo Motor Show in October of 1968. Considered by many to be the first “superbike”, it was an absolute game-changer of a motorcycle.
Best of all, the CB750 didn’t cost an arm and a leg. Despite features like a 296mm front hydraulic disc brake, five-speed gearbox, quality lighting, electric starter, and industry-defining reliability, it was a shockingly economical bike. The CB also got a compact five-speed transmission with a wet multi-plate clutch, hydraulic fork, dual rear shocks, and a rear drum brake. Weighing in at 495 lbs, the CB750 and its tubular steel duplex frame wasn’t exactly light, but the powerful engine put down 67 hp at 8,500 rpm and was capable of reaching speeds of up to 125 mph.
By 1974, the K4 model had become the best selling motorcycle in America with some 60,000 units leaving dealer showrooms annually. Although, not the most powerful “superbike” on the market, the small refinements, improved fuel efficiency, and various color options made the bike immensely popular with riders across the country.
