Hello Donato.
I know "you can not precisely predict how long it will takes you to crate and clear the bike through Both the customs" and I also know that "Dakar's harbor properly itsn't a carnival."
But I also know that many said it was not possible to go through certain streets with a Gold Wing as my o ... a Harley like yours.
The challenge is not only to go to a place, not just go with a motorcycle, but also to go in a certain time. And I like it. I love traveling "fast".
In any case, I travel fast, not "in a hurry". There is a subtle difference.
Travelers "in a hurry", must necessarily go home within a day.
I do not, I do not "I", I "want" to go back to a certain day. It 's different.
If a month late, it does not happen anything serious, from the point of view of work, I lose a month's pay, not the work, from the point of view of the family, my wife will be sorry, but do not let me down.
I work, I can ask four months and then only use 2, when I come, the day I resubmit my expectation at work / vacation stops automatically and everything returns to normal.
I start planning 2/3 months and my wife knows that I plan to return in this period, but if, by my calculation errors (unlikely: I have never been wrong these accounts in my travels) or events that are my own will, it will take a month more, patience is not the end of the world is nothing irreparable.
Each of us travel in a different way.
