This is a picture taken in 1948 of Max BuBeck (On cycle) and his tuner Frank Chase. This bike went 135.58 mph and still holds the title of fastest unstreamlined Indian Motocycle ever.
The cycle is considered a "Chout" because it's a chief engine in a scout chassis. But definitely no ordinary chief! This one ran methanol through two Schebler barrel valve carbs and was running cams ground by the legendary Fred "Pop" Schunk.
