Data are sources by local authorities deputy for the new vehicles registrations in any single market and then aggregated within our unique Global Motorcycles Database.
The most of data are received by official sources, the National Minister of Transportation or deputy agency. Sometimes data are purchased by the local Association of Motorcycles Distributors or Motorcycles Manufacturers.
In some countries in Asia, local authorities do not report on imported vehicles and we integrate their figures with those directly collected by the manufacturers or their distributors.
Usually data refer to new vehicles registrations, while for India and Brazil refer to wholesales.
As far as China, while we actually have the total market figures and several brands/model, we still miss the total pictures.
