About the Suzuki GS400S
A part-by-part application guide for the Suzuki GS400S.
GS400S coverage varies by component. The application table brings the carburetor, pivot and control choices together so a year for one part is not mistaken for coverage across the motorcycle.
Start with the job and the S designation
For carburetor work, distinguish the bowl gasket from the float needle and seat. For chassis work, identify the swingarm pivot or the fitted handlebar control. The table gives the year boundaries; the repair links lead to the corresponding products.
Model and year comparisonGS400S parts differences
Years apply to the part. Check its full fitment and the component fitted to your motorcycle before ordering.

| GS400S | Swingarm bearing set | 1981–1982 | Two bearings, each 22 × 29 × 30 mm. |
| GS400S | Fuel tank cap | 1984–1986 | Compare the actual filler neck and venting. |
| GS400S | Ignition switch | 1984–1986 | Compare connector and mounting. |

Use GS400E parts or GS400L parts when those suffixes match the motorcycle. The GS400 family comparison includes early base-model parts.
