Suzuki GS1100 parts for repair and restoration
Suzuki’s GS1100 line includes different final-drive layouts: the E parts catalog shows a chain case, while the G-model parts catalog shows a propeller-shaft final drive. The oil filter, engine gasket set and fork seals below are separate replacements with their own model and year applications.
Oil filter
The oil filter covers GS1100 1980–1984 and is sold individually. It replaces Suzuki reference 16500-45810; check the number and filter dimensions before ordering for a suffix model.
Engine gasket set
The engine gasket set covers GS1100 1980–1981 and is sold as a set. Review its product details for the engine work you plan to do and confirm the model code before ordering.
Fork oil seals
The fork-seal set measures 37 × 49 × 8 mm and covers GS1100 1982–1983. Match all three dimensions to the seals in the installed forks, especially if the front end has been replaced.
Choosing parts for your GS1100
Check the drivetrain code: The GS1100E uses a chain case; the GS1100G uses a propeller-shaft final drive. For drivetrain parts, match your bike’s full model code. The oil filter uses Suzuki reference 16500-45810.
Keep the year range with the part: The oil filter covers GS1100 1980–1984, the engine gasket set 1980–1981 and the 37 × 49 × 8 mm fork seals 1982–1983. One part’s years do not carry over to another.
Measure the installed fork seals: The fork-seal set measures 37 × 49 × 8 mm. Compare inside diameter, outside diameter and thickness to the removed seals before fitting a replacement front end or ordering parts.
