Superbike championship, but Honda went on to win the next five years in a row of series championships with the Interceptor. As the popularity of the series grew the long established Daytona 200 motorcycle race, which had begun on a course constructed on the beach in 1935, and had moved to the asphalt auto-racing track in 1961, switched to Superbikes. The race had been one of the few venues where FIM style Formula 1 500cc machines raced in the United States, but by 1988 the speeds the machines were reaching on the high-banked tracks were simply too high for safety given the tire technology of the time. In 1985 the race format moved from GP bikes to Superbikes, and it became part of the AMA Superbikes series. This increased the visibility of Superbikes even further, and cemented in the minds of many Americans that the Superbikes were now the de facto premier motorcycle racers, eclipsing the FIM 500cc series, with their unavailable two-stroke racing machines. 2003 to 2008: Return of the liter class In late 2002 AMA Pro Racing, the promoter in charge of the AMA Superbike Championship at the time decided to open up the series to 1000cc production bikes. Their plan called for allowing near-stock 1000cc machines to compete against the then-current state of the art 750cc Superbikes that were the incumbent series competition machines. In addition, they would be allowed to increase their capacity to 800cc. The complicated rules allowed "claiming" of the 1000cc stock machines, a technique where competitors can buy the winning machine from the owner for a set amount of money, and intended to keep modifications down in near-stock racing classes. Ultimately this complicated mix of machines and rules was not liked by many of the competitors. In 2006 Ducati withdrew factory support from AMA Superbike racing, and in 2008 Honda followed suit. 2009 to 2014: Daytona Motorsports Group From 2009 to 2014, the Daytona Motorsports Group was the organizer under supervision of the AMA. The AMA, not pleased with motorcycle counts and participation in their events, stripped the DMG organization of the sanction and awarded it to a new organization led by Wayne Rainey, KRAVE, with assistance from Dorna (which organises the FIM MotoGP and World Superbike Championships). 2015 to Present: MotoAmerica takes charge, FIM alignment KRAVE organized multiple championship road racing series for the AMA, which are collectively known as the MotoAmerica
