AMA Pro Racing changes bike list for AMA Formula Xtreme 2007
Friday, August 11, 2006 - AMA Press Release


AMA FORMULA XTREME TO EXPAND EQUIPMENT ELIGIBILITY

PICKERINGTON, Ohio (August 11, 2006) -- The American Motorcyclist Association (AMA) and AMA Pro Racing today announced changes to the equipment eligibility list for AMA Formula Xtreme beginning with the 2007 racing season.

AMA Formula Xtreme is a support class of the AMA Superbike Championship, the nation's premier motorcycle road racing series.

Beginning next year, production motorcycles featuring engines with the following displacement and specifications will be eligible for competition in the AMA Formula Xtreme class:


550cc-600cc 4-stroke liquid-cooled 4-valve four cylinders

650cc-675cc 4-stroke liquid-cooled 4-valve three cylinders

650cc-850cc 4-stroke liquid-cooled 4-valve twin cylinders

990cc-1100cc 4-stroke air/oil-cooled 4-valve desmo twin cylinders

990cc-1200cc 4-stroke air/oil-cooled 4-valve pushrod twin cylinders

900cc-1350cc 4-stroke air/oil-cooled 2-valve pushrod twin cylinders

In making the announcement, AMA Pro Racing Director of Technical Development, Kevin Crowther said the changes were consistent with the intent of the Formula Xtreme class and reflective of the current motorcycle marketplace.


"The goal of the Formula Xtreme class is to feature highly-modified machines from the broadest list of models," said Crowther. "These changes are consistent with that philosophy and should lead to increased brand and rider participation in the class."


Crowther added that emphasis was placed on equipment diversity as well as competitive balance.


"If it becomes apparent that a specific model or type of machine gains an unfair performance advantage, AMA Pro Racing reserves the right to implement restrictions including, but not limited to, additional weight to restore competitiveness," said Crowther. Crowther noted that this stipulation applies to the Formula Xtreme class only.


The changes to the eligible model list are the result of actions taken by the newly-formed AMA Racing Committee created earlier this year as part of a re-organization of the AMA and AMA Pro Racing.


Equipment standards for the remaining classes (AMA Superbike, AMA Supersport and AMA Superstock) remain unchanged.


Rules adding 1000cc motorcycles to AMA Superbike, the premier class of the championship, were announced in 2002 for the 2003 racing season and will continue at least through the 2008 racing season. Current AMA Superbike rules feature 901-1000cc four-stroke engines with two or more cylinders, exclusively.

Can you say Team Triumph Formula Xtreme Daytona 675?

I think the sole purpose of this change was to include the Buell XB-RR and Triumph Daytona 675 (without being "questionable"). Both Buell and the AMA took a ton of flak for letting the XB-RR compete.

P.S. You post twice, I post twice
