Armstrong for militray use world wide, Harley Davidson also built these machines in York, PA. under license. Power unit is by Rotax of Austria, the same motor used in dirt-track racing in the U.S. With the insistence that all military vehicles must use diesel fuel, gasoline powered motorcycles are now obsolete.
