Same advice as I gave to someone else before... bring a tent, but don't make it the center of your strategy.

In Western Europe, the cost of a tent pitch in a campsite is not less than the cost of a hostel bed. And in a hostel, you get a roof, heating, and a shower. Once you get out of Europe, accommodation simply becomes very cheap. Camp on the days when you are far out in the countryside, the scenery is beautiful, and the weather is nice.

Brief notes on your route:

1) You're going through Switzerland which means an expensive highway vignette (unless you want to stick to local roads for the challenge of it), but you are completely bypassing Austria and the North Italian mountains. Carinthia and the Dolomites are some of Europe's best riding areas - don't forgo them in favor of the boring and stressful autopista on the flatlands.

2) You're spending time in Albania and Macedonia, but completely bypassing Bulgaria - any reason for that?

3) If you make it all the way across Turkey, you absolutely owe it to yourself to ride in Georgia. It is one of the world's great tourist destinations, and with plenty of interest to moto travelers.

4) ...meanwhile the south and especially southeast of Turkey is super tense - it's essentially the staging area for a war that Turkey is fighting in Northern Syria, and locally with the Kurds. I'd cut through the center and avoid the border areas.

5) To my understanding, there is no open land crossing between Lebanon and Israel (and Syria is still closed for war). Maybe go from Turkey to Cyprus (check the border formalities between North and South Cyprus) - there's a ferry service from Limassol to Haifa IIRC.

6) Crossing the Sinai on a motorcycle is a question mark. Sometimes it's forbidden, sometimes people make it through. Be prepared for delays and trouble.
