The following release is from AMA Pro Racing... AMA Pro Racing confirmed today that the 2006 Daytona 200 will again feature Formula Xtreme motorcycles and that the class structure for the AMA Superbike Championship remains unchanged. The class structure for 2006 is as follows: Superbike: 901-1000cc four-stroke, two or more cylinders Supersport: 0-600cc four-stroke, multi-cylinder Formula Xtreme: 450cc-600cc four-stroke, multi-cylinder; 595cc-750cc four-stroke, liquid-cooled, twin-cylinder; 850cc-1350cc four-stroke, air-cooled, twin-cylinder Superstock: 745cc-1000cc four-stroke, multi-cylinder AMA Pro Racing announced on May 26 that 1000cc motorcycles will remain in AMA Superbike through the 2008 racing season. Rules adding 1000cc motorcycles to the class were announced in 2002 for the 2003 racing season. As noted above, current AMA Superbike rules feature 901-1000cc four-stroke engines with two or more cylinders, exclusively. “The feedback over our announcement regarding 1000cc machines remaining through 2008 has been very positive,” said Scott Hollingsworth, AMA Pro Racing CEO. “This stability as well as that in the support classes is designed to encourage greater rider and team participation across the board.” Formula Xtreme machines are used for the Daytona 200 because of the unique demands placed on equipment specifically at the Daytona International Speedway course. As part of a major infield renovation completed at the facility prior to the beginning of the 2005 racing season, the infield road course was also reconfigured. These changes, coupled with switching the 200 to Formula Xtreme equipment, were made in the interest of improving safety at the track. AMA Superbike remains the premier class within the championship with AMA Supersport, AMA Formula Xtreme and AMA Superstock serving as support classes. Technical rules for each class will be announced at a later date. The subtext here is "We're sick of Mat Mladin winning the Daytona 200 so we're going to make sure he doesn't by not having it open for Unlimited Superbikes" Yes, I know it's fast and yes, I know the superbikes had tyre problems there in the last few years the 200 was run as an open event, but it seems a little too parochial for this Aussie race fan and Mladin himself thinks that the move had more to do with politics than it did with safety. Relegating the Superbike race to a 15 Lap Support Event sucks in my opinion.
