I'll agree that the basic, most valid answer is "it depends." Beyond that, I'm just noticing that where you've been specific about easily-quantifiable costs (visas, fuel, shipping, CDP, flights, etc.), you're either underestimating or counting on everything going just about perfectly. With my US passport, I'd spend a lot more than this on visas--if you're Swiss, this might be different for you. I've definitely spent more on fuel in just a year. A CDP would cost me quite a bit more, as have flights.
Plus: your budget doesn't appear to include many of those optional extras which sometimes turn out to be the real point of a trip--special tours and activities, or the times when you leave the bike behind in order to, say, go to Antarctica, take a dugout up the Sepik, sail through Guna Yala, or learn to [choose any three of the following: rock climb, kite sail, scuba dive, ski mountaineer, go spelunking, speak another language, mountain bike, kayak amongst whales, paraglide, bungy jump, play the kora.....and more like this].
Caveat: I've not done an actual around-the-world trip, and I don't tend to track expenses very closely. I definitely leave a considerable margin for error when budgeting for long journeys, and I'm usually glad I did.
Hope that's helpful.
