buying a bike in central america questions
 

I know this is way in advance from when we are going to do be doing it, but figure if I start searching now it will help in the long run.
Me and the Mrs to be are kicking around the idea of spending approximately 1 month (hopefully December) motorcycling around central America in 2015 for our honey moon. Its pretty regular that you see bikes for sale in Panama and CR but there is so much info out there that its hard to tell what the process is. As far as what country to buy in we are open to anything with a major airport to save on flight costs, and it seems most are willing to meet all over central America if they are selling a bike. Its hard to tell what info is accurate, and what is mis information regarding buying a bike down there and hopefully getting it through borders without issue, and back north eventually

What would be ideal for me to do is buy a Canadian bike and have the sale lined up before the seller even heads south on their own trip. That way I could ask them to get a second copy of their Canadian registration and mail it to me, then register the bike in my name before even heading down. Then exchange the funds for bike when we arrive down in CA and voila! A bike registered in my name in central America. But I am sure that wont happen
So the other options are buying probably a USA registered bike while in central America, or a Canadian bike when we get there. I plan to try and line up the bike in advance of us leaving so hopefully the day we arrive the ball can start rolling.
But in what country should we be looking to buy, and why? Ideally we will be looking for a KLR,DR,XR since she will be on the back, and they have the right size for 2 up riding, most for sale have some panniers for our goods, and they are basically bullet proof.

So really looking for all the inside info available on buying a bike in central America. The final plan will be to have the wife fly home and I will probably ride though mexico back to the USA and store the bike until the following spring. Or else store the bike in central americAmerica head back there to ride the bike back north in the following spring.
Any help or ideas are appreciated
