Iver Johnson Arms & Cycle Works was located in Fitchburg, Massachusetts, and better known for its firearms than as pioneer motorcycle manufacturers. Production ran from 1907 to 1916, with this V-twin being the final design.
These machines were labeled "mechanical perfection," where in fact they had many mechanical features, such as the cam operation and clutch, that were unnecessarily complicated.
