As the fastest production machine, it easily out-accelerated any other machine (2 or 4 wheeled) in its day.
Although the KZ1000 speed is not on par with today's modern sport-bike standards, it is still impressive for a carbureted 'muscle-bike' with points ignition (pre-'79) and is a popular platform for a lot of top-fuel and pro-stock drag bike competitors.

Kawasaki ditched the traditional 4-4 exhaust (available on Z-1 and KZ900) for a cheaper and a more easily produced 4-2 exhaust. This was a move made by Kawasaki to supposedly keep up with the sheer demand for the KZ1000 motorcycle and to target a broader consumer range.
The KZ1000 series came in either a chain drive or shaft drive ('79-) to turn the rear wheel.
KZ1000 Tires and Rims
The KZ1000P (police) sits on 18 inch wheels with Dunlop run-flat tires. The front tire is size MN90-18, and the back tire is size MR90-18. They came in either a cast magnesium or chrome-plated wire spoke rims.
The KZ1000 came optional with a wind jammer fairing, saddle bags, a sissy bar and highway bars - all of which were removable without any interference with performance or function.
The fairing and saddle bags were molded fiber-glass resin made by Vetter, while the sissy bar and highway bar were chrome plated to accentuate the look.
Highway bars were also used for comfort on long trips that didn't require constant shifting or braking and usually held additional lighting, in combination with the single 7 inch halogen head lamp. Some newer accessories readily available include cafe fairings made by EMGO and Lockhart. For drag racing applications, POD filters often replace the stock airbox for an increase in air volume and velocity.
