HONDA CB750 K (1977-1978) Specs, Performance & Photos

The Honda CB 750 K was a motorcycle made by the Japanese motorcycle manufacturer from 1978 to 1982, presented at the 1978 IFMA Show in Cologne, as a successor to the CB 750 Four and available for sale later that year.

"What happens when you keep winning races" was the phrase presented along with the bike that featured a DOHC engine design and several other new features. The engine was based on the one used by the RCB943 and RCB997 models, with four valves per cylinder and two timing chains for the intake and exhaust cams.

The alternator was moved from the left side to the right side of the engine for better balance and also featured a transistorized ignition system that offered smooth performance and more fuel efficiency. Also, the braking performance was increased with two discs on the front and a lower and deeply padded seat that offered more comfort and handling.

For suspension, the bike packed a telescopic fork on the front and two shock absorbers on the rear, while the braking performance was handled by a 275 mm disc with a hydraulic caliper on the front wheel and an a180 mm drum braking unit on the rear that provided decent stopping power.

In the performance department, the 1978 Honda CB 750 K had its heartbeat set by a 748cc four-stroke four-cylinder air-cooled engine fueled by four Keihin carburetors that helped deliver an output power of 77 hp with maximum strength at 9,000 rpm and 65 Nm (48 lb-ft) of torque available at 7,000 rpm.
