Don`t let them stole your bike or car!
The "worst case" is that you have to pay the import-tax!
This can be a completely fantasy price.
I take tunesia as sample:
There is a form, where you can calculate the import tax for your car (dont know if also for bike)
A Toyota Landcruiser V8 with a listprice of 60`000-70`000 Euro has an importax of 230`000 Euro. They stole your Landcruiser in Tunesia
Worst case is, that you cant leave tunesia, bevore the issuer of the carnet had pay the 230`000 Euro. You loose the caution, and have to pay back the difference when you are back at home.
Your insurance, if you have them - will replace the car/bike - so no worry there. But mostly NOT the import tax....
That is worst case.
Here are some german biker`s theyr Bikes got stolen: they had luck, and have only to pay a small bill.

I think mostly you will find an solution, without to take "worst case", but that needs time and effort. So better look after your stuff
As is start looking for insurance or so, everything looks after "no problem". Then i ask for this import task stuff, and they need a week for clear that up at carnet issuer and insurance: the importtax is your risk (tourinsurance.de, tcs)
So asks your insurance. When you found one who covers something like this: tell me - i want them!
Hint: I don`t found one sample of worst case in the internet. And only one case of stolen vehicle named above. So this risk is there, but not so big
