A Little History of the Kawasaki S3

The Kawasaki S3 replaced the S2 350 with a 400cc two-stroke triple aimed at smoother, more emissions-conscious street performance. It kept the distinctive Kawasaki triple personality while making model-specific carburetor, ignition, brake, and chassis parts important for restorers.

Popular Kawasaki S3 searches include S3 carburetor parts, ignition parts, brake shoes, fork seals, control cables, engine gaskets, seals, and chain-drive components. Check year, submodel, market version, and the part already installed on your motorcycle before ordering. Older machines often have swapped parts, aftermarket repairs, or previous-owner fixes that can affect fitment.
