Production years: 1973, 1974
In 1974, the motorcycle maker launched the Honda CB750 Four K4, a motorcycle kept in production for only one year with around 60,000 units manufactured that were available in three color schemes, such as Flake Sunrise Orange, Freedom Green Metallic, and Boss Maroon Metallic.
The bike also featured white, gold, and black gas tank stripes, smaller side covers than on the K0 model without slots in the leading edge, chromed upper fork, black headlight housing, and larger taillight and turn signals than on the K1 model.
It also featured a two-cable operated throttle with one pulled to open and one pulled to close, a four-into-four exhaust system with four mufflers, and a four-cylinder air-cooled engine linked to a five-speed manual transmission.
In addition, the bike came equipped from the factory with standard features, such as an analog instrument cluster, a chromed dual exhaust system with two mufflers on each side, a dual seat, a wide handlebar, a center stand, and wire-spoke wheels.
As for the power, the 1974 Honda CB750 Four K4 packed 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.
The 1974 K4 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.
