When I saw the web site, I was wondering what racing venue they had in mind. I speculate that they may well promote a spec class (along the order of the Boxer Cup, but probably more grass roots) in Europe or possibly elsewhere. Aprilia have done that type of thing before. I know ~8 years ago they had an Aprilia 125 cup in Switzerland (and elsewhere in western Europe, I believe) based on the street repli-racers. Like the Tuono, the bikes were sold with all street parts, as well as the racing conversion parts.
More recently they have run the Aprilia 250 Cup here in the US.
There must be a reasonably sized club racing scene where such bikes are popular in Europe, because Ducati Performance carry quite a few race-only components for Monsters.
With the growing popularity of more sporting naked bikes (such as the new Kwacker, the F1, Ducati Monster and now the Tuono) maybe a big time racing series for such bikes could be successful. Could have real spectator appeal.
