In Spain you can drive any motorbike 125cc and below with a regular driver's license. A 125 is also legal on any road in Spain so in theory you could drive across the country on their best superhighways. We bought a Piaggio 125 and love it. We are also in an area where it hardly ever rains, you can ride year round and the roads and scenery are spectacular.
So, what kind of license would you need if your bike was bigger than 125cc? Like 1175cc bigger.
