The Indian Model O, a 265cc lightweight horizontally opposed twin. Manufactured towards the final years of WWI, the Model O was Indian's attempt at capturing a younger customer who may not have the cheddar for the big bikes of the day. Unfortunately the tiny displacement didn't thrill young riders, the war effort made production and sales very difficult, and the explosion of mass produced, reliable, and affordable automobiles marked the end of the Model O by 1919. I doubt he won any races with his tricked out Model O racer, but he was out there, and sometimes thats all that matters.
