Kawasaki engineers, horrified at this well kept secret launch, returned to the drawing board and redesigned the bike to be bigger and better. In late 1972 the Z1 was introduced to the world and instantly became a best seller. The idea of a four-cylinder four-stroke was conceived way back in 1967, when Kawasaki focused mainly on developing two-stroke motorcycles. The decicion was made to develop a high-performance motorcycle which would far exceed the 650W1, the largest motorcycles in Japan that time. The goal was a fast, yet comfortable 750cc motorcycle with good handling and brakes. Coordinated by Sam Tanegashima, a project planning group was established and development code T103 was born.
In 1970, the Z1 developing project team was reunited with the best staff in all the fields joining the project. This group repeated research and experiments to develop an even better bike. Kawasaki resumed U.S. market research in March of 1970 and collected customers' opinions from various sources such as random samplings of dealers and editors of major motorcycle magazines. Finally, the management staff concluded there was a strong market for a high-speed, eye-appealing motorcycle with enough power to use as a reliable touring model
The Z1 went on to become the basis of most of Kawasaki's models for many more years, changing the face of motorcycling forever. Never before had the average man had the chance to own the fastest, biggest, most technically advanced motorcycle in the world for so little money.
