The Excelsior


Excelsior followed the growing trend in the United States and introduced a 45 degree v-twin motorcycle in 1910. The Excelsior grew to 1000cc in 1912 and soon proved to be a sporting machine when it became the first motorcycle to officially break the 100 mph barrier.

The 750cc Super X was introduced in 1925. This model was the first of a new breed of American 45 cubic inch machines. It featured unit construction, leading link forks and a duplex cradle frame.
