This collection brings together parts tagged for the 1971 XS1B, including engine, carburetor, electrical, brake, clutch, cable, exhaust, gasket, suspension, wheel, lighting, and restoration components.
The 1971 XS1B shares some parts with the 1970 XS1 and 1972 XS2, but early XS650 models can still have year-specific details.
