In March / April 2017 I have to send my bike (Honda Gold Wing 1500, now has 915,000 kilometers) from Italy to South America and at the beginning of June 2017 I have to return it from Alaska to Italy.

I planned to take the America, from the extreme south to north (Tierra del Fuego - Alaska).
Starting the beginning of April (or the end of March), return the end of May (or early June). Two months, about 25,000 km.

The key points are.
1) The costs are not the main problem. My primary need are the times (faster), and the least possible complications. Obviously, if I have to choose between a budget of € 1,000 and a € 5.000, I am willing to endure some "discomfort" or delay. This is because my journey is, as mentioned before, a quick trip, where the priority is the respect of the times. Also I do not want to be without motorcycle too long before (is my only means of transport), nor too after (I have other appointments on a motorcycle in Italy in the second half of June).
2) The interruption of the road between Colombia and Panama will overcome with the airplane.

I know that air travel, especially for a heavy and large motorcycles (and little "compressible") like mine, are expensive. I also know that there can be many differences (in the My World Tour, 4 flights, the differences were remarkable). But, as I wrote at the beginning, at this stage interest me more time and mode (from where to where) that the exact cost.

In summary, now I ask you advice on the delivery of the bike from Colombia (Medellin or Bogotà) to Panamà with airplane.
Thank you
