Motorbike license - driving course for foreigners (Istanbul)

Dear All,

brave or stupid - you decide - but with summer around the corner, I have decided to get myself a motorbike. Only challenge is that I don't have a valid bike license and therefore would need to go through the process here in Istanbul.

I am not so worried about the actual driving/riding, but understand that you also need pass a theoretical exam..in Turkish. With my Turkish vocabulary limited to "sag","sol" and "dur" it is going to be a bit of a challenge to pass such a test, I am afraid.

Anybody knows of any companies in Istanbul conducting driving courses for foreigners or alternatively know whether it is possible to sit a theoretical exam in English anywhere ?
