The Kawasaki KZ400/Z400 is a street motorcycle manufactured by Kawasaki from 1974 to 1984. The dual cylinder engine’s displacement was raised to 443cc for the KZ440/Z440. A 399cc two-cylinder engine powered the subsequent KZ400-J.
From 1974 until 1984, the Kawasaki KZ400 was a 398 cc two engine motorbike. To decrease vibration, the engine included two balancer shafts, one in front of the crankshaft and one behind it, both moving in the opposite direction of the rotating crankshaft. An emission control system reused “by-product” gases. It was marketed as a “most practical all-around machine” by the producers.
Later variants displaced 443 cubic centimeters. The KZ400 was manufactured in Akashi, Japan, and Lincoln, Nebraska. With the construction of the Lincoln facility in 1974, Kawasaki became the first foreign motorcycle manufacturer to have a plant in the United States. Throughout the 1970s, the KZ400 outsold Honda in the 400 cc twins market. These bikes were touted as fuel-efficient vehicles; a 1975 magazine commercial for Kawasaki displayed the KZ400 next to a Volkswagen Beetle with the tag line “Think even smaller.”
Early versions had oil leaks and erratic idling. Beginning in 1977, both the carburetors and the architecture of the oil passageways were modified. Some variants were available as basic transportation, with no electric start and front drum brakes. Most, on the other hand, featured a single disc in front and a drum in the back, as well as electric and kick starters. A fairing and saddle bags were also included on the deluxe versions.
