The following is a list of motorcycle manufacturers worldwide, sorted by extant/extinct status and by country. These are producers whose motorbikes are available to the public, including both street legal as well as racetrack-only or off-road-only motorcycles. The list of current manufacturers does not include badge engineered bikes or motorcycle customisers, but the list of defunct manufactures may include some of these if they are well remembered for their historical significance. This transport-related list is incomplete; you can help by expanding it.
