the Duc is a 1198...why wouldnt a 1125 be allowed or a 1000 RSV. wait til the KTM comes out.
The Ducati is an 848. The 750 will not be allowed, and the 1125 and RSV will be overmatched by the 600's at nearly all tracks. So that shouldnt be a problem. The KTM will get stomped by the japanese bikes on all fronts, so I dont think anyone is too worried about it.
