Thanks everyone for the useful info!

Maybe I'd need to clarify some more things: my wish is to ride mainly through rural areas, mountains and desert. Through cities, I will only ride when absolutely needed, otherwise park at some accommodation and use local public transport or taxi.

The idea behind having a license and bike registration was so that I don't get bothered too much on checkpoints or if they catch me riding to fast, or other minor things like these, which could escalate badly if the officer has a bad day and I can't show any other papers beside my passport and original license. Granted, if they have a really bad day, I suppose no papers could really save me, but it's good to have them nonetheless, I reckon.

The idea behind some insurance would be to have it "just in case". I was, for example, involved in an accident in India in 2015. The police were really friendly and helpful, once I presented them all the papers and they were all in good order. That's the sort of situation where an otherwise cheap and almost negligible insurance can make a big difference. I ended up with a busted knee that had me limping for a few weeks, but I suppose that' another price that one sometimes needs to pay for riding a bike and not being too careful at it.

All in all, I don't have too many concerns, I just want to avoid the things that, starting from minor traffic "incidents", could land me in a really bad situation.

One more thing, any info where I could check what kind of bikes would be found on the market? A dual sport would be nice, as I suppose the mountain roads aren't exactly fit for superbikes..Also service network for the brand is something to consider, as the bike will need servicing from time to time.
