AMA SUPERBIKE CHAMPIONSHIP TO VISIT VIR IN AUGUST

PICKERINGTON, Ohio — AMA Pro Racing has confirmed the AMA Superbike Championship presented by Parts Unlimited round at Virginia International Raceway (VIR) in Alton, Va., tentatively scheduled for Sept. 17-18, is now confirmed for the weekend of Aug. 26-28.

Prior to the date change, the race was to be a two-day meet highlighted by a single round of the AMA Superbike Championship. The expanded three-day format now calls for an AMA Superbike Championship doubleheader along with all support classes including the Pro Honda Oils Supersport Championship presented by Shoei, AMA Repsol Lubricants Superstock Series and Lockhart Phillips USA Formula Xtreme Series.

The event will be promoted by RPM Productions.

“The VIR date has been listed as tentative on our calendar since the schedule was originally released. In finalizing the championship schedule we felt an earlier date along with making the event a Superbike doubleheader was a positive step for the series,” AMA Vice President, Commercial Development John Farris said.

“Also, the addition of RPM Productions as a promotional partner should help ensure continued growth of the event,” Farris added.

With the additional VIR Superbike round resulting from the doubleheader format, the 2005 AMA Superbike Championship presented by Parts Unlimited now includes 17 races on the season. The 2005 schedule gets underway at Daytona International Speedway, March 9-12, and concludes this year at Road Atlanta, Sept. 2-4, for a Labor Day weekend doubleheader.
