About the Suzuki GS450GA
Engine, fuel and brake repairs for the automatic GS450GA.
The GS450GA pairs an air-cooled twin-cylinder engine with a torque converter, two-speed transmission and shaft drive. This drivetrain makes the GA designation essential for transmission-related work and for comparisons with manual GS450 models.
GS450GA engine gaskets and brake year ranges
The GA engine gasket set and caliper rebuild kit cover 1982–1985. Other components have narrower coverage: the float valve covers 1982–1983, and the linked front pads cover 1982–1983 plus 1985. These distinctions stay attached to each repair link below.

Engine gaskets and caliper kit
Both linked components cover this GA range.
Parts checkpoint: Compare the supplied repair pieces with the work planned.

Use these details to match your motorcycle and any replacement assemblies before ordering.
- Confirm the complete GS450GA designation and model year.
- Identify the torque-converter transmission and shaft-drive arrangement rather than relying on the GS450 badge alone.
- Record engine identification and any replacement assembly history.
- Photograph carburetor markings and the fitted front caliper when selecting float-valve or brake parts.
