My permanent address is London but I live part the year in Spain where I keep a Spanish-registered KTM 690 and a Spanish-registered Panda 4x4, both of which have Spanish insurance (AMV for the KTM, Linea Directa for the Panda) and the insurance very handily covers me for Morocco.

Registering a bike in Spain (even just buying new) is a terrible exercise in red tape and it's normal for most people to use a Gestoria to handle this at a cost of several hundred euros. Made much worse if you buy a bike in one region, but live in another, when the costs double. So I have some sympathy for @Jagermini.

The Spanish vehicles need to be registered to YOUR property in Spain (don't know how @Jagermini achieved this). The Spanish equivalent of road tax is charged by the local council to the registered owner so if the transfer papers aren't completed correctly the previous owner gets annual charges ad infinitum.

The rules about temporary use of a foreign registered vehicle probably differ from country to country, but in the UK you are limited to an accumulated six months in any one year. Being an island it's pretty difficult to fiddle this, but if @Jagermini is living in Italy who can tell if he claims his bike is out of the country much of the time. However... the UK six months only applies if you are NOT permanently resident in the country, and Italy might be similar.

Having said that, both Italy and Spain are countries where they pass loads of laws and then everyone ignores them (that's not meant as a denigrating comment).

But the really important thing, as @TwoWheelsGood writes, is the small print on the Spanish policy.
