A Harley...any Hardley. Just to get it over with and finally know what an over hyped piece of garbage they actually are.
Honda Ruckus. Because it's fun passing Hardley's on the outside of corners in Chuck Taylor's with Chinese take out strapped on the back.
Kwack ZX-Ten...because if you haven't ridden a modern Literbike on the street...you probably like Hardley's & GS's. This bike is the CR Five Hundred for the street, especially the Oh-Five Gen I...wailing siren of Satan constantly tempting you until the Po-Po take your license away.
ZRex -- The UJM your mind thinks was bikes in the Eighties.
