Kawasaki KZ750 Parts (1976–1984) – OEM & Aftermarket Motorcycle Parts

Looking for high-quality Kawasaki KZ750 four-cylinder parts? This collection is dedicated specifically to the inline-four KZ750 models, including the 1983 KZ750 L3, and does not apply to KZ750 twin-cylinder motorcycles.

Produced during the early 1980s, the Kawasaki KZ750 four-cylinder represented a transitional moment in Kawasaki’s lineup. By 1983, performance-focused GPz models were evolving rapidly toward modern sportbikes, while the KZ series branched into what Kawasaki positioned as sport-cruiser and standard motorcycles. The KZ750 L3 shared much of its DNA with the earlier GPz750, but featured more restrained styling and a standard riding position rather than full sportbike ergonomics.

Distinguishing features of the KZ750 L3 include its inline-four air-cooled engine, classic standard layout, and unique factory graphics — notably the three horizontal stripes along the fuel tank and tail section in orange, red, and yellow. Lacking the fairing typical of GPz models, the KZ750 four-cylinder emphasized everyday rideability while retaining strong performance. Kawasaki’s inline-four engines from this era are widely regarded as robust, durable, and easy to service, making these bikes highly desirable among riders and restorers alike.
