These figures are sourced from the Central Statistics Office (Ireland) and encompass both motorcycles and scooters, as the CSO does not differentiate between the two categories. However, additional context has been incorporated into this data. Some brands are not listed individually; for example, Royal Enfield and Benelli are grouped under the "All Other Brands" category. In 2024, Moto Guzzi was added as a separate brand. Niche or less common brands, such as LML, Kubota, and Peugeot—which may sell only one or two bikes every few years—are also included in the "All Other Brands" category.
