The Kawasaki KZ400 is 398cc twin cylinder UJM Universal Japanese Motorcycle. This term is blurred today with the various models Japan builds. Few of which look like the UJM of the 1970s and 1980s. Kawasaki produced the KZ400 from 1974-1984. Some of the later models were 440cc. They were built at plants in Akasi, Japan and Lincoln, Nebraska. The Lincoln plant (1974) made Kawasaki the first the first foreign vehicle manufacturer to operate a plant in the United States. KZ400s outsold Honda in the 400cc twins market through the 1970s. These motorcycle were marketed as fuel efficient transportation. Ads would feature the KZ400 next to a Volkswagen Beetle and the tagline "think smaller."
