So the twins are going to be the 650-700cc Japanese twins and the smaller Italian twins up to 850? Just skimming the rules, those are going to be pretty expensive motorcycles to build with all the mods they allow. Plus the bikes are allowed to be pretty light.; 300lbs including all fluids for the Japanese twins and 320lbs for the Ducatis. Sounds like a pretty interesting new class to me. Sort of a builder bike class for privateers, but who knows... We might see Graves 700 Yamahas!
