Many automakers dabble in building motorcycles, in addition to selling four-wheeled transportation. In a case like Volkswagen Group and its ownership of Ducati, the parent company runs the bike business under completely separate branding. Conversely, BMW and Honda make no effort to hide their involvement in the cycle business.
These renderings run with the concept of imagining a variety of automobiles and car brands as their motorcycle equivalents. See if you agree with how these vehicles transform from four wheels to two.
