America's motorcycle museums are a delightful place to see motorcycles that you are unlikely to find anywhere else—rare motorcycles, antique motorbikes, prototypes, etc.
In addition to dedicated motorcycle museums, this list contains some auto and transport museums which have motorcycles on display. It is advised to contact the museum if you cannot determine from their Web site that they will have a significant quantity of motorcycles on display during the time you intend to visit.
The museums in this list are "brick & mortar" places, which may or may not offer rich online content. At a minimum, their Web sites provide museum visitation information. It is strongly recommended you to confirm that a museum is open before visiting. Some have seasonal hours.
