Ducati has been testing a heavily revised version of the GP11 chassis for sometime now.  Its team manager Vittoriano Guareschi who also doubles as a tester along with regular tester Franco Battaini have been testing it for a while now though neither of the two factory team riders have tried it as yet.  It was being believed that the new chassis could be introduced for the Estoril GP but now it seems that the old chassis will be used in the race and Nicky Hayden will get to test the revised version only on Monday.  There is no world yet on when Valentino Rossi will get his hands on to it.  Ducati has been experiencing huge problems with the exit of Casey Stoner whose genius as a rider made light of the shortcomings of the Ducati and propelled it to many victories and a World Championship as well.  No one else, including Valentino Rossi thus far has looked like winners on the bike.  What a great pity that Casey Stoner is not more likeable.
