But what makes an "American" bike? There are few large manufacturers of motorcycles in the USA. Of course, Harley-Davidson is the name we all think of, cranking out more than 300,000 bikes a year. But there is also Victory, made by snowmobile-and-ATV-builder Polaris, as well as a slew of custom builders. Where is the "American Sportbike," Harley-owned Buell? We decided to put them in the Sportbike section: These bikes are built as performance machines.
