Kawasaki KZ650 Parts (1977–1983) – OEM & Aftermarket Motorcycle Parts

Looking for high-quality Kawasaki KZ650 parts? Whether you ride an early KZ650 standard, a performance-oriented model, or a cruiser-style variant, this collection includes the essential components you need to restore, maintain, or keep one of Kawasaki’s most versatile four-cylinder motorcycles on the road.

The Kawasaki KZ650 was introduced in the mid-to-late 1970s as a middleweight alternative to the larger KZ900 and KZ1000 models. Powered by a 652cc air-cooled inline-four engine, the KZ650 delivered strong performance, smooth power delivery, and the durability Kawasaki was known for. Its balanced size and weight made it equally suitable for everyday riding, long-distance use, and performance-oriented applications.

Certain variants, including early SR-style models, featured distinctive styling changes such as revised frames, smaller rear wheels, unique fuel tank and seat designs, and cruiser-influenced ergonomics. Some models incorporated comfort-focused updates like rubber-mounted footpegs and integrated warning indicators, while later versions continued to evolve toward more standardized layouts. This variety has helped the KZ650 earn a loyal following among restorers, riders, and custom builders alike.
