1000CC SUPERBIKES TO CONTINUE THROUGH 2008 PICKERINGTON, Ohio (May 26, 2005) — AMA Pro Racing said today that it will continue to utilize 1000cc-based equipment in the AMA Superbike Championship through the 2008 racing season. Rules adding 1000cc motorcycles to the class were announced in 2002 for the 2003 racing season. Current AMA Superbike rules feature 901-1000cc four-stroke engines with two or more cylinders, exclusively. According to AMA Pro Racing CEO Scott Hollingsworth, fan interest in AMA Superbike is expanding. “Ratings for SPEED Channel’s television coverage of the AMA Superbike Championship are 19% higher this year than 2004, and coverage of last weekend’s Superbike race from Pike Peak was the highest-rated AMA Superbike broadcast of the year,” said Hollingsworth. “Similarly, through the first five events of 2005, we’re on pace to see record-setting attendance. With the announcement of 1000s continuing at least through 2008, we’re confident we’ll see continued improvement in the overall quality of racing and fan enjoyment.”
