First
internal combustion motorcycle. Actually, the first "motorcycle" recorded in the history books was created in 1869 by Sylvester Howard Roper, an American inventor - you guessed it, powered by steam. He also built steam cars. Everything that is powered by internal combustion, you can be sure was powered by steam many years before.
Here is a pic of the 1869 model. The first "hog".

Later models could do 40mph.
