Developed mainly by young Kawasaki engineers, the Zephyr’s design concept was to create a “real” bike that “got back to the basics”. Released in the middle of the racer replica boom of the mid 1980’s, the Zephyr’s refreshingly simple design, low and mid range performance, air-cooled four-cylinder engine, and the prevalent idea of “fun riding” change the market as motorcycle fans swiftly respond to the new machine. Sales exploded and the Zephyr was declared the best-selling 400cc machine up until 1992. The boom period was named the “Myth of the Zephyr”.
When sales of the Zephyr 750 and Zephyr 1100 started in 1990 and1992 respectively, they also created great sensations.


UMG Says: Neat looking four with reasonable handling and engine that hasn’t been properly developed – a mildly tuned four needs a singe carb for frugality, torque, smoothness and cheapness. Nevertheless, a pleasant enough device on the road that’s sufficiently tough to take the usual neglect and abuse. Some bargains out there with poor cosmetics (that can be sorted cheaply) plus plenty of good low mileage stuff. Also 50hp grey 400 version.

IGM Says: Although a very good bike, this isn’t noticeable better than its predecessor, the KZ550, but it costs more. Still, if you can find a deal on a ZR550 Zephyr, you’ll have a great motorcycle.
