HONDA CB750 Four KZ 1978-1979

After the lunch of the CB750 F2 model, Honda decided to further develop the CB750 machine in touring terms and came up with the CB750 Four KZ, which in essence, was a K7 motorcycle that retained the original layout of four separate exhaust pipes with redesigned mufflers.

The bike featured two subtle modifications, such as the repositioning of the front turn signals and the removal of the front fork shrouds, which helped convince potential customers of Honda's ongoing research and development while boosting the sales of the bike.

Also, the fuel tank remained the same with a new look due to the different paintwork and lining, while the most positive change featured by the KZ model was the position of the ignition switch and choke controls in front of the steering head.

In the horsepower department, the 1979 Honda CB750 Four KZ had its heartbeat set by a 748cc four-stroke four-cylinder air-cooled engine fueled by four Keihin carburetors and delivered 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.

The power generated by the engine was converted into motion by a six-speed manual transmission that spun the rear wheel through a chain drive to a top speed of 200 kph (125 mph).

As for braking power, the model featured a 275 mm disc squeezed by a hydraulic caliper on the front wheel and a 180 mm drum braking unit on the rear wheel that offered optimum braking performance.
