}} American Flat Track,[1] is an American motorcycle track racing series. The race series was founded and sanctioned by the American Motorcyclist Association (AMA) in 1954.[2][3] Following the 2016 season, AMA Pro Racing announced the official re-branding of the all-new American Flat Track (AFT) series – formerly known as AMA Pro Flat Track. The re-branding of the series coincided with the dawn of a new era for America's favorite motorcycle sport, which includes a restructured class system as well as a re-envisioning of the event format. While holding true to the legacy of a sport rich in history, the modifications are designed to provide a more understandable and exciting format for the modern fans and make the series more accessible to new fans. The race series encompasses four distinct forms of competitions including: mile, half-mile, short-track, and TT steeplechase dirt track races. The restructured class system consists of the AFT Twins class, the premier class where the best Flat Track riders in the world battle for top honors on fire-breathing Twins, the AFT Singles class, which will host dirt track racing's stars of tomorrow and the newly-announced AFT Production Twins class featuring production-based, twin-cylinder motorcycle engines from BMW, Ducati, Harley-Davidson, Honda, Kawasaki, Suzuki and Yamaha street bikes with displacements between 649-800cc. AFT TwinsThe AFT Twins ChampionshipAFT Twins is the pinnacle of dirt track motorcycle racing globally, and has been since the professional ranks were formalized as the Grand National Championship in 1954. Beginning this year, riders in this class will race each circuit on custom-built, twin-cylinder motorcycles generating 90+ horsepower race bar-to-bar at speeds in excess of 140 mph, often drafting to the finish line and requiring a photo finish to determine the race winner. The motorcycles in this class contain the latest in motorsport technology and will be piloted by the fastest two-wheeled athletes on dirt. Quick Facts

AFT Production TwinsAs AFT Singles riders progress and set their sights on becoming an AFT Twins rider, the AFT Production Twins class gives up-and-coming athletes the opportunity to race an AFT track on a twin-cylinder race bike without competing against the heavy hitters in contention for the AFT Twins championship. This class serves as a transition between the AFT Singles and AFT Twins classes. Quick Facts
History1920s – ORIGINS OF THE SPORT: American Flat Track is one of the original and longest-running forms of motorsport, with roots dating back to the first two-wheel speed demons in the 1920s. Harley-Davidson's Jim Davis won the first national race sanctioned by the AMA, the 25-mile AMA National Championship which was held on a one-mile dirt oval in Toledo, Ohio on July 26, 1924. 1930s – INTRODUCTION OF CLASS C: In 1932, the AMA sanctioned Class A Dirt Track allowing motorcycle manufacturers to enter prototype machinery. Class C was introduced in 1933, featuring street-legal motorcycles and focusing on cost containment to attract new riders. AMA crowned Indian-mounted Woodsie Castonguay its first Class C National Champion in 1935, and the final Class A champion was crowned in 1938. 1940s – HARLEY VS. INDIAN: While Europe began to boil over, the Great American war raged stateside. Class C helped fuel an intense rivalry between Harley-Davidson and Indian, the two major American manufacturers of the period. Due to the Second World War, no championships were held between 1942 and 1945. All other years, the Class C winner at the Springfield Mile was crowned National Champion. 1950s – HARLEY VS. BSA: Up until 1953, the AMA Grand National Champion was crowned based on the results of a single race, the Springfield Mile. In 1954, the AMA formalized a series of events known as the Grand National Championship, featuring five different types of race circuits. Four were dirt tracks, while the fifth was a paved road course. With the demise of Indian Motorcycles in 1953, Harley-Davidson was left to dominate the series, with rider Joe Leonard winning the first Grand National Championship in 1954.1960s – HARLEY TAKES ON THE BRITS: In the 1960s, British manufacturers seeking to bolster sales in the burgeoning American motorcycle market began to compete in the championship. Dick Mann won the national title for BSA in 1963, marking the first victory for a foreign manufacturer. Triumph would win three Grand National Championships in four years, with Gary Nixon winning back-to-back titles in 1967 and 1968, and Gene Romero taking another title in 1970. 1970s – EVOLUTION: THE RISE OF THE JAPANESE: Mann won a second crown for BSA in 1971 before the British motorcycle industry collapsed. In 1973, Kenny Roberts took the honors as Grand National Champion for Yamaha, the first for a Japanese marque. In 1975 Ken Roberts possibly scored the first points riding a two stroke, a Yamaha TZ750 in a Champion frame, winning the event – the first he had ridden the bike. His famous words, "They don't pay me enough to ride that thing." signaled the impending doom of the two strokes and multi-cylinders other than twins. In 1978, Roberts took the international scene by storm. His revolutionary style, bred on American dirt tracks, allowed him to dominate his competition and become the first American to win a motorcycle road racing world championship. Roberts was the catalyst that set off a firestorm of world champion motorcyclists bred on American dirt track racing. 1980s – BIG BATTLES: H-D & HONDA HEAD-TO-HEAD: Honda brought engineering and technical superiority to the sport in the mid-1980s, earning four championships in succession from 1984 – 1987. As the sport grew and machinery became increasingly specialized, the AMA recognized the need to separate the dirt and asphalt disciplines. In 1986, flat track and road racing became two distinct AMA Pro Racing championships. Tammy Kirk became the first woman to score GNC points in 1983. Scott Parker began his historic championship run for Harley-Davidson in 1988. 1990s – DOMINANCE: HARLEY REIGNS SUPREME: With the exit of Honda, Harley-Davidson dominated the sport relatively unopposed throughout the 1990s. In 1993, the Harley-Davidson 883 Sportster division was introduced, featuring nearly street-legal bikes. Chris Carr won championships in 1992 and 1999, and Scott Parker claimed an unprecedented nine championships by the end of the decade. In 1999, the SuperTracker division was created, introducing a large number of DOT-approved four-stroke, twin-cylinder engines to the sport. 2000s – DIVERSIFICATION: A CHANGE OF FOCUS: The SuperTracker division was absorbed into the GNC in 2001. In 2002, Shaun Russell finished 13th at the Springfield TT on a Honda CR250, marking the final time points were scored by a two-stroke motorcycle. Chris Carr won his seventh and final championship in 2005, which was also the final season for the Harley-Davidson 883 Sportster Division. In 2007, Nichole Mees became the second woman to score points in the GNC. 2010s – A RENEWED INTEREST: New manufacturers began to enter and find success in the sport. In 2010, Ducati earned its first GNC win. On August 24, 2013, three different OEMs finished on the podium for the first time since 1972. One week later, Harley- Davidson failed to make the podium for the first time since 1987. With Bryan Smith at the controls, Kawasaki emerged as a fierce competitor on Miles. Race Circuits
