Here's a picture of my grandfather (rider) on his 1920's Militor. I believe the photo is from the early to mid 1930's. The Militor was an inline 4 cylinder motorcycle that was produced in various locations from 1910 to 1922. I have also included a picture of a restored Militor that is located in the Springfield Museum in Massachusetts and an older photo of the bike from a magazine.
I guess bikes are in the DNA.
