Buying a bike in the americas- help wanted
 

hey there,
maybe you can help me out here...

here a short explaination of the situation..
My girlfriend and I are planning to travel in the Americas. I have some experience driving and and international permit (just finished a trip from thailand to belgium on a ttr250), she doesnt has a licence...

We wanna buy 2 small secondhand motorcross/enduro bikes (400's) somwhere in the americas, for keeping the costs low..we are on a very small budget...

Questions:
1. wich is the easiest and cheapest country to do this?

I heard its better in north america (Los Angeles and San Diego) and that you need to make up an temporarly adress, insurance can be hard for motorcrossbikes...
Is it really to difficult in South America?

2.If we have once a registered bike (from us or can or...), can we go everywhere we want in the Americas? and sell it later for example in the south? or do we have to drive it back?

3.I heard my girlfriend can also go for her motorcycle licence in the US. anybody experience with that?

If you have any other ideas let me know.
It all seems quiet difficult to me. just want to find the cheapest thing to do. maybe its in the end better that we ship here from belgium, because we dont need any carnet at all...

any advice more then welcome...

greetz and see you on the road
