1927 Indian Scout "Wall of Death"
The Wall of Death is a term used to describe a silo or barrel shaped wooden cylinder with a diameter of 20 to 26 feet. The audience would look down inside these cylinders as the riders performed their tricks. These shows began in 1911 at Coney Island and began a national carnival attraction with more than 100 "motordromes" in traveling shows and amusement parks in the 1930's.
This 1927 Indian Scout was modified for the specific purpose of the "Wall of Death" attraction and was a preferred motorcycle for these shows. Though its peak in popularity is long past, performances can still be found at various venues throughout the United States.
