HONDACB750 Four K3 1972 - 1973

　　In 1973, the Japanese motorcycle manufacturer launched the Honda CB750 Four K3, a naked machine that was available in three different colors, such as Flake Sunrise Orange, Candy Bacchus Olive, and Maxim Brown Metallic.

　　The gas tank featured white, gold, and black stripes, the side covers were smaller than the ones on the K0 without slots on the leading edge, chromed upper forks, black headlight housing, and larger taillight and turn signals than the K1 model.

　　The CB750 was a game changer for the face of motorcycling in three ways, such as the design template set for the modern superbike with its four-cylinder engine and high-tech specifications, it cemented the Japanese manufacturers as the new force of motorcycling, and with its combination of quality, value, and performance effectively sounded the final death knell for the ailing British motorcycle industry.

　　The 1973 K3 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, while the braking performance was handled by a 296 mm disc squeezed by a hydraulic caliper on the front wheel and a 179 mm drum unit on the rear.

　　In the performance department, the 1973 Honda CB750 Four K3 took its thrust 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.
