Kawasaki 6 Cylinder Motorcycle - Kawasaki Z1300

Kawasaki Motorcycles has a 55-year-long history and produces some of the world’s fastest and most affordable motorcycles. The company only produced bicycles in its early years to minimize costs and develop a brand name. In 1969, Kawasaki manufactured the first two-stroke three-cylinder Mach II motorcycle. This motorcycle’s popularity in the global market became a turning point for Kawasaki.


Kawasaki has produced several well-known motorcycles, including the Kawasaki Ninja and Z series. While focused more on manufacturing speedy and affordable sports bikes, Kawasaki only managed to produce one 6-cylinder motorcycle known as the Kawasaki Z1300. This article discusses the specs and performance of the Kawasaki Z1300.

The Kawasaki Z1300 is large in size, with a wheelbase of 65.2 inches. It was a challenge to place a carburetor next to each cylinder, with the crankcases being extended as a result. The engineers decided to go with three twin-choke vacuum carburetors. The water-cooling system helped to reduce the engine’s size slightly.


The Kawasaki Z1300 had a simple design with its fuel tank painted black and the borders colored red with gold linings. Its saddle offers enough room for both the rider and the passenger.
