1904 Marsh Pictures

The 1904 Marsh was little more than a motorized bicycle, but was nicely designed and one set up for racing could go 60 mph.

The 442-cc single-cylinder engine had an atmospheric overhead intake valve and a mechanically activated side exhaust value.

In a practice common at the time, the Marsh used the engine as a structural frame member.
