In 1969, Honda of Japan introduced the CB750 motorcycle to the US and European markets after the success they had with smaller motorcycles. The CB750 was a standard motorcycle that offered an upright seating position and was powered by an air-cooled four-cylinder engine, but also the first bike called a "superbike."

The CB750 was included in the AMA Motorcycle Hall of Fame Classic Bikes, was named "Greatest Motorbikes Ever" by the Discovery Channel, was in The Art of the Motorcycle exhibition, and was in the UK National Motor Museum.

In 1973, the Japanese motorcycle manufacturer launched the Honda CB750 Four K2, a naked machine available in three different colors, such as Brier Brown Metallic, Flake Sunrise Orange, and Candy Gold.

It also featured gold stripes on the fuel tank, smaller side covers than on the K0 with no slots on the leading edge, chromed upper fork, black headlight housing, and a larger taillight as well as turn signals.

The bike featured a tubular steel duplex cradle frame that housed a non-adjustable telescopic fork on the front and dual shock absorbers with preload adjustability on the rear that provided optimum suspension performance.

As for the power figures, the 1973 Honda CB750 Four K2 took its muscles from a 736cc four-stroke four-cylinder air-cooled engine fueled by four Keihin carburetors that helped deliver an output power of 67 hp with maximum strength at 8,000 rpm and 60 Nm (44 lb-ft) of torque available at 7,000 rpm.
