Indian Boardtrack Start-up
Some of the earliest racing motorcycles ever made, boardtrack racers of the 1910s and 1920s were raced on banked, wooden circuits, mostly in the United States. Essentially bicycles fitted with powerful, large capacity v-twin, multi-valve engines, it was one of the most dangerous sports of its time - for both riders and spectators. In this video by Netherlands dealer Yesterdays.nl, an original 1915 61cu.in. (1000cc) Indian is fired up by stationary rollers. Very advanced for its day you can clearly see the four-valve heads in operation - it sounds fantastic too!
