The Western Suburbs Motor Cycle Club approached Sydney Smith for a loan of the paddocks, known as Belmore Park, situated to the west of Smith's home, Thornton Hall. The Council loaned its road grader and a flat dirt circuit was made and Penrith Speedway was born. In 1925, Smith and his family floated Penrith Speedway as a public company, with Smith, the chairman of directors. Six thousand people attended its first meet. In March 1925, the Club improved the track. Penrith Speedway was at this time declared the world's largest dirt track. Then in 1928, it was declared one of the fastest dirt tracks where drivers could get up to 90 miles per hour.The last meeting of the Speedway was held in May 1941.
