Don't you have to take any sort of test to ride a bike over there?
When I began riding I had an all day test,morning in school yard,afternoon on roads.
Then a few lessons on a 125,then lessons on a 500,then an exam called 'hazard perception' where you watch a film and have to spot hazards as early as possible,then I sat a mutiple choice exam on the highway code,then I had to do a practical test on the 500.
Not legal until all this is done and passed.
This took me about 3 months,some people take longer,some less time.
