While the '75 Z1-P basically was a Z1 900 with a shop-installed kit, the 1976 C2 was factory-built as a police motorcycle. This motorcycle was manufactured by Kawasaki Motors Corporation's U.S. plant in Lincoln, Nebraska. The model was designed in cooperation with Kawasaki, police departments, and the automotive designer and race car driver Dan Gurney. It featured a new bag design and slightly different badging than its predecessor.
Would love to get some more info about these early Police bikes, so if you're sitting on some documentation, please contact me.
