Description

Additional photos on this 1975 Kawasaki Z1 900 are available here for your perusal.

One of the most important bikes of the 70s, the Kawasaki Z1 set all sorts of speed records at Daytona within a year of its debut.

The Z1 has a fun story – Kawasaki thought they were going to be first to market with a 4 cylinder 750cc sport bike…and then Honda blew them away with the CB750. Kawi wisely decided to go bigger instead, and the 903cc powerplant impressed the press and customers with 82 horsepower. In their home market of Japan, the government mandated a displacement limit of 750cc, so Kawasaki created the smaller Z2 instead.

1975 brought enough changes that the chassis code became the Z1-B – said changes included more power, better suspension, better brakes, and a stiffer frame. Styling tweaks included different paint color options and different logos on the sidecover.

This example is VIN: Z1F50281. The seller purchased it from the original owner in West Palm Beach, Florida over a year ago.

During his ownership, the seller has covered 121 miles. The odometer shows 21,258 miles.

The engine is not original – the original owner and selling dealership have provided documentation as to what happened and those documents can be viewed here:

The original engine number was Z1E-050312. The replacement engine number is Z1E-070886. The dealership that replaced the engine was told by Kawasaki’s Warrany Administration that “apparently, a few engine cases on the line in Japan got mixed up during production. Kawasaki Z1 engine cases are mated due to the fact that they are line bored at the factory once bolted together. This means that the engine cases have to stay together and cannot be interchanged. [This] was unfortunately one of the motorcycles that received mismatched engine cases.”
