Looking for high-quality Suzuki GS450 parts? This collection includes OEM and aftermarket replacement parts for all Suzuki GS450 models, covering GS450E, GS450L, and all factory variants. Whether you’re restoring a clean survivor or keeping a well-used rider on the road, you’ll find the essential components needed to do the job right.

Introduced for the 1980 model year, the Suzuki GS450 was developed as a more powerful evolution of the GS400, aimed primarily at the North American market. In Japan, motorcycles over 400cc fell into a higher tax category, but that limitation did not apply in the U.S., allowing Suzuki to increase displacement and deliver stronger performance. The result was a mid-size twin that retained the GS series’ proven engineering while offering improved torque and highway capability.

Powered by an air-cooled parallel-twin engine with double overhead camshafts and two valves per cylinder, the GS450 was known for smooth power delivery, durability, and everyday usability. Its balanced design made it popular with commuters, touring riders, and vintage enthusiasts alike. The GS450 remains a respected classic and a solid platform for long-term ownership today.
