Here you can ride wherever you want, except 50 cc on highways.
There are several licenses. A1 since125cc or 15hp. A2 up to 47 hp. and A for more than it. You need to have A2 for 2 years before ti try to get the full A.
The E.U laws just changed this Jan Kiki. Now thro-out E.U countries they ought to all be the same. Before when you gkt the upgraxe to ride anything after 2 yrs of passing your test, now new riders dont get that. If/when i now pass my test on a 125cc i am permanently limited to riding 125cc's forever. If i want to ride bigger bikes i must sit the test on a bigger bike, i think theres now 3-4 classes of license for different sized bikes. You will be ok if you passed before Jan 2013, if you havent and are still on L plates then you will be affected.
Lots of folk didnt know about the changes, i only found out a month or so before they came in
