Sorry Dennis, the picture you have above is that of Gottlieb Daimler's "Zweispur"
The American steam model was by a Mr Roper and looked like this. He died riding this or a similar one in the 1890's at above 40 mph
He was only 73 at the time. He started playing with the steam motorcycle in the 1860's
