Brina, I'm bringing this back from the dead. I hope you are still around.
I am in the process of moving to Tunis for work and want my 990 to accompany me.
A couple of things:
1.) Did you have any luck bringing a large displacement bike into Tunisia? If so, can you provide some more details.
2.) Can you give the name/location of the KTM dealer you found in Tunisia? I have heard of a dealer in Tunis/La Marsa, but have not been there yet.
What I think I know on the subject is that as an ex-pat/foreigner, I can import my 990 Adventure and apply for RS plates. These plates would allow me to bring the motorcycle into the country and own it there. I would not have to pay the 104% tax on it, but I would not be able to sell the motorcycle in the country (not planning too).
I will be back in Tunis the later half of January and hope to clarify these points. If they come back positive I will be crating up my 990 in February to ship over.
