I enter under English race licence, but you would be well at home because its the Ducati Club Races with the Dutch crmc having a round of their championship. I was there last year and there was a few of the center steering Ducatis there from Italy in fact there was a lot of italians there. My road bike is a 916 Biposto so i was well pleased.
Just had a look at the entry for last year...Enrico Cairo from Cadrezzate, Emiliano Lazzarini from Portovaltravaglia, Roberto Airoldi from Galliate to name a few. Ok they were racing in the Ducti races but i am positive that you could race in the classic, not sure about the front brake.
The only reason we have to have a drum front is the bikes have to look a bit like the Hailwood 500, in our class in England there are lots of guys who have discs,
if you are interested i will do all i can to help you get there, and i'm sure if you ever wanted to come to England to race i would be more than happy to help and meet you to make sure all was ok
