The '''Kawasaki Z1''' is a high performance [[superbike]] [[motorcycle]] produced by [[Kawasaki]] from 1973 to 1975. | |||

[[Kawasaki]]'s earlier two and three-cylinder bikes such as the [[Kawasaki H1|H1]], and [[Kawasaki H2|H2]] had bestowed Kawasaki with a high performance image. But these bikes had known problems: excessive fuel consumption, noise, vibration, and less than perfect handling. Their sparse comfort relegated them to the role of street racer.

Kawasaki engineers had outlined these limitations of their two-stroke triples as early as 1967. This led to the beginning stages of planning a four-stroke super cruiser in the mold of the 1000cc Vincent, that could be ridden in any situation, and would be "THE" bike all experienced riders lusted after. | ||

For 1974 Kawasaki changed the colors and markings, and the engine dropped the black paint to simply be an aluminum color. In mid 1974 there was a slight [[carburetor]] change to improve cold running. At the end of 1974 Kawasaki had produced over 80,000 units of the Z1 and [[Kawasaki Z2|Z2]]. | |||

Kawasaki dropped the automatic chain oiler in favor of an o-ring chain. The front forks received revised dampers and softer springs. To improve low speed running there was a new automatic ignition advance. Unlike on the trend with the H1 these changes didn't drop performance. | |||
