Ok thanks for that information! This is what I was worried about...
So then it could be an option to buy a bike in California and go south from there. But then I have the problem of seasons. I wanted to be in Ushuaiha somwhere around march and then go north again to be in the USA around august... I don't think I will make it down there if I start in California in december.
On the other side it should be pretty easy for me to buy a bike in the US since I have a swiss/us dual citizenship

So, if you want to do a world trip on one bike you're better off buying American or taking your own bike. Me personally I find it crazy that people take their own bike. Purely because they spend my travel budget for a year just on shipping the bike. Then inevitably have a break down or two (or for some reason need parts) and end up stuck in a country which doesn't have the parts paying extraordinary amounts to get them shipped to them.

Your problem with buying in North America and riding south is crossing the Darien. You're looking at $2000 ish to ship the bike and yourself. For me, that's the cost of a bike. Which you can sell when you're done and recover most of the cost.

People are still buying and successfully riding Chilean bikes with a "decleracion jurada" which states that you'll return to the country within 12 months. Crossing the border with this if someone questions it will come down to your Spanish skill level and charm. Approaching the aduana as an extranjero with no Spanish and expecting a smooth ride with a sullen face will not go well.

I haven't heard of people having issues with Colombian bikes so it might be a better option. Again, the CRF250L is expensive. The xr150l or xr190 is much cheaper. Personally I'd suggest buying in south America (new) riding around and reselling in south America before moving to your next location and buying something there again. For example you might fancy coming to Australia after south America. Here we have an abundance of good second hand bikes. So shipping a dr650 here for example would be pretty pointless.

If you've got $100k to spare on a 4 year RTW trip then by all means buy a new DR650 in North America and go for it.

Here's the thread (sticky) about buying a Chilean bike. It's kept up to date and makes for good reading if you consider buying from there. Seems with the declaración jurada people aren't getting the troubles they used to.

And here's a link to a thread discussing how to buy a bike in Colombia

Ushuaia to Usa, March to August - or Usa to Ushuaia December to March - whats the hurry? Dont you want to have a look around and see interesting places and relax at some beaches, hike some mountains and visit some far flung places?
Did you count for breakdowns? Waiting some weeks for spare parts to arrive or maybe not arrive, and some more weeks waiting for spare parts to arrive... Maybe a decent foodpoisoning or two? A bad flu and maybe pneumonia? It easily sets you back many days each.

Some persons do travelling only for the sake of travelling, Nick Sanders rode Alaska to Ushuaia and back to Usa again in 50-60 days or around that timeframe - but for most people I think stopping here and there smelling the roses, relax a bit, explore some new countries and take in some new environments is the main thing about travelling. Not only the feeling of having the bike under you 10 hours a day...

But ok, I see your point. March is not the best time to start southbound from the Usa. Will meet the rainy season in central America from June and onwards. If youre really quick you can make it to Panama and Colombia before the rainy season really are on. So July and onwards would be ideal for the Andes mountains, Peru, Bolivia, north of Chile and Argentina. Can be a bit cold of course. Then maybe October/November start towards the southern part of the continent, be in Ushuaia beginning of December. Hurry back to Valparaiso or Montevideo and ship your bike to next continent before christmas/new year.

Yep as mentioned the Crf250 are a bit expensive in south-America. Maybe better to go for the Honda Tornado 250 or the Yamaha Lander 250 or Tenere 250. Ir even the ubiquitous Honda Xr150L or the newer 190. Or even the Suzuki Dr200.
But in Usa the Crf is quite cheap. And so is a decent Dr650 too. Well - you have many decisions in front you. Best of luck with them and your travels!
