BTW, still looking for any early (and by that I mean Pre-WW1) pictures of H-D motorcycles used by US armed services. I am sure they were testing motorcycles before their big orders in 1916 - 1917. But have never found a single picture of early bikes (singles in particular) as tested by US Army. Wrote the Army Transportation Museum and they have nothing. But someone has to have SOMETHING on the earliest military use of a HD Single or Twin. I am pretty sure they were using motorcycles in the Punitive Expedition against Pancho Villa. And if they were doing that, they must have tested them earlier
This picture is from a picture book called "Somewhere in Mexico",copyright 1916, the pictures are of the battles fought against Pancho Villa. It is one of a pair of books (can't find the other, my brother must have it), that my grandfather had. Not the greatest picture of the bikes, but as you can see the Army certainly had motorcycles in that era, and there must be more pictures out there somewhere.
