American Flat Track
American Flat Track (AFT) is one of the oldest forms of motorcycle racing in the United States. Races take place on flat dirt oval or semi-oval tracks. Originating in the 1930s, it is now one of America's most important motorcycle speed racing series.
Race History
Flat Track originated during the Great Depression in the United States, when mechanics held informal races on dirt tracks. In 1937, the AMA began organizing an official championship, which gradually developed into today's American Flat Track Championship.
Race Classes
AFT is mainly divided into two classes:
- AFT SuperTwins (1100cc twin-cylinder engines, premier class)
- AFT Singles (450cc single-cylinder engines, entry-level class)
Since 2017, AFT has introduced a twin-cylinder class to replace the original AFT Twins, bringing the series closer to the traditional engine character associated with Harley-Davidson.
Track Types
AFT tracks are divided into three types:
- Mile (1-mile oval track)
- Half-Mile (half-mile track)
- Short Track (usually one-eighth mile)
Different track types test riders' acceleration and cornering skills.
Notable Riders
Legendary riders include Flat Track Hall of Fame members such as Chris Carr and Carrie Hill in the women's class. Contemporary riders include Jared Mees, Brandon Robinson, and Henry W.aines.
Differences from MotoGP
Unlike MotoGP's streamlined racing machines, AFT uses highly modified naked-style street motorcycles, emphasizing high-speed stability on flat dirt tracks. Engine setup and rider weight distribution are key technical factors.
Safety Equipment
Riders must wear helmets, chest protection, and protective suits, and use boots fitted with metal or plastic toe sliders. Although safety equipment continues to improve, AFT remains a high-risk sport and serious accidents occasionally occur.
Cultural Impact
AFT holds an important place in American motorcycle culture. Cultural elements shaped by Harley-Davidson and racing are deeply rooted in American motorcycling culture.
