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.

Building a Custom KZ750?
Some parts on a custom build are not model-specific. If you’re changing handlebars, mirrors, lighting, controls, shocks, exhaust pieces, fuel line, or hardware, visit our universal and custom motorcycle parts collection.
These parts are useful for cafe racers, brat builds, trackers, choppers, and garage-built vintage motorcycles, but they are not guaranteed to fit every bike without checking. Always compare measurements, mounting style, clearance, and product notes before ordering.
