1920 Indian Scout 'Burt Munro Special' — the 1920 Indian Scout portrayed in the film started life as a 600 cc motorcycle with a designed top speed of 55 mph. Munro's streamlined record-setter was substantially modified; with capacity being increased to 950 cc, and a recorded speed of 205 mph. These modifications were largely done in Munro's workshop, using basic methods and tools as depicted in the film. Four motorcycles are used in the film to depict the actual 'Munro Special'; two of which were replica Indian Scouts, the others being Ducatis.
