The Kawasaki Zephyr was a range of Retro-styled naked motorcycles made by the Japanese motorcycle manufacturer in the 1990s. The bikes were part of the Z series in Kawasaki's range and were available in four engine configurations, including 400, 550, 750, and 1,100cc displacements.
The Kawasaki Zephyr 1,100 engine was based on the air-cooled DOHC inline-four unit used on the GPZ1100 and Z1000 models and was the only machine featuring two spark plugs per cylinder.
In the visual department, the bike was fitted with standard features, such as a round headlight with the instrument cluster mounted on top, a one-piece dual seat with a passenger grab handle, a four-into-one exhaust system with a muffler on the right side, and five-spoke lightweight aluminum wheels.
The bike was built around a single cradle steel frame with a 43 mm telescopic fork on the front and adjustable side-mounted shock absorbers on the rear, offering optimum suspension performance and handling.
The braking power was handled by two 310 mm discs tied to dual-piston calipers on the front wheel and a 240 mm disc coupled to a two-piston caliper on the rear wheel, providing optimum stopping power.
As for the power figures, the 1991 Kawasaki Zephyr 1100 had its soul brought to life by a 1,062cc four-stroke four-cylinder air-cooled engine that delivered an output power of 93 hp at 8,000 rpm and 89 Nm (66 lb-ft) torque at 7,000 rpm.
