List of motorcycle manufacturers

The categorization of manufacturers by country of origin reveals clear regional industry characteristics: Japanese brands hold over 40% of combined global mass market sales led by top volume producers Honda, Yamaha and Suzuki, while Italy hosts one of the world's highest concentrations of premium performance marques focused on track racing and high-end leisure riding. China and India have grown to be the largest 21st century production hubs, with hundreds of local manufacturers catering to domestic affordable commuter demand while increasingly exporting electric and entry-level models to global markets.

The reference list intentionally excludes small custom motorcycle workshops that do not design and manufacture core powertrain and chassis components in-house, only adding brands that have sold complete branded motorcycles for at least one full formal production run. It also explicitly separates entries for fully operational active brands from defunct historic marques that permanently ceased production, making it a widely trusted reference for motorcycle collectors and regulatory industry documentation.

The regular revisions to the Wikipedia page act as an informal timeline of global motorcycle industry evolution: in the 5 years leading to 2026, the number of new electric motorcycle manufacturer entries added far outpaced new internal combustion engine marques added to the list, clearly documenting the ongoing global transition toward low-emission two-wheeled mobility.
