There’s be some trouble brewing in the MotoGP/WSBK camp after news hit that MotoGP would be switching back to a 1000cc format by the 2012 season. In that story, several possibilities on how that format would work were put forth by various sides, one such proposal being the running of production based motors in MotoGP.

These motors, which would be based off those found on streetbikes, could be tuned to any degree, provided it met the criteria in the MotoGP rule book (1000cc & four-cylinders are the only regulations agreed upon currently). This news of course drew the ire of World Superbike promoter, Infront Motor Sports, in the form of Paolo Flammini, who believes that format would infringe on his license to exclusively run a production based race series.

Refusing at first to define what a production engine is, Dorna’s Carmelo Ezpeleta is now switching gears and saying the term “production engine” won’t even appear in the new MotoGP racing regulations.
