48. 1977 Kawasaki KZ1000
The Kawasaki Kz1000 or Z1000 is a motorcycle made by Kawasaki and was released in September 1976 as a 1977 replacement model to the 1976 KZ900. It had an in-line 4-cylinder engine configuration paired with a 5-speed transmission. Generating about 90 hp, it was considered the fastest production bike of the era. In 1979 Kawasaki introduced the Z 1300 liquid-cooled, 6-cylinder engine configuration, which became the powerplant for their Voyager series. Both were available for several years and the police model continued into production until 2005.
