Hundreds of motorcycles show the styles through the decades, including the flashy rides of Elvis and Evel Knievel. You can sit in the saddle of various bikes (on the bottom floor, in the Experience Gallery) and take badass photos. Even nonbikers will enjoy the interactive exhibits and tough, leather-clad crowds.
It all started in 1903, when Milwaukee schoolmates William Harley and Arthur Davidson built and sold their first motorcycle. A century later the big bikes are a symbol of American manufacturing pride. The museum is located in a sprawling industrial building just south of downtown.
