This collection includes OEM and aftermarket replacement parts for all Suzuki GS550 models, covering GS550E, GS550L, GS550M, and other factory variants produced between 1977 and 1986. Whether you’re restoring a stock classic or maintaining a reliable vintage rider, you’ll find the essential components needed to keep your GS550 on the road.

Introduced in 1977, the Suzuki GS550 was part of Suzuki’s all-new four-stroke lineup, developed to compete directly in the rapidly evolving middleweight four-cylinder market. Alongside the GS750 and GS400, the GS550 represented Suzuki’s commitment to modern, high-performance four-stroke engineering. The GS550 filled the sweet spot in the lineup, offering strong performance in a lighter, more manageable package than its larger siblings.

Powered by an air-cooled inline-four engine with double overhead camshafts and two valves per cylinder, the GS550 delivered smooth power delivery, impressive reliability, and a broad usable powerband. Features such as electric start, front disc brakes, and a well-balanced chassis made it a versatile motorcycle suited for commuting, touring, and spirited riding. Produced through 1986, the GS550 remains a respected and highly rideable vintage Suzuki today.
