Cannot import and register used bikes in Chile
 

With respect to importing a used bike into Chile (and registering it there under Chilean plates), this has been not permitted under the law there since about 1998. Various angles have been tried but few have been consistently successful. In theory, some " returning Chileans" may have the right to bring one vehicle after living outside Chile for some considerable period of time. Supposedly you can import a NEW zero-km auto or bike, but almost definitely not a used one. Applies to foreigners and Chileans alike. Some people (me included) will sometimes buy used KLR650 for the value of spares and accessories - we are located in Puerto Natales, in southern Patagonia.

For me selling/donating a bike illegally is not anoption in either chile or argentina as I visit both yearly and need reentry without problem. If there is a way leaglly I will be interested in selling it when I arrive (if all other options fail). As I said before my wife is a chillean citizen living in states for over 10 years and that will be my first approach.
Another solution may be to dump in Peru when finished.

Thanks.

cannot import used bikes/vehicles in Chile
 

As mentioned earlier, neither foreigners nor Chilean nationals can legally import a used vehicle into Chile. There are a few exceptions but they are very limited. Chile allows residents of the I and XII regions to do a limited use ("red plates") importation but the use of that vehicle is restricted to those regions (I and XII regions). Red plate vehicles can get short term permission to briefly visit the rest of Chile. How do I know this? Because all of my KLR rental fleet bikes except one are on red plates (I run tours of the XII region and southern Argentina/Tierra del Fuego with red plate bikes). If a foreign rider wishes to unload a bike in southern Patagonia (XII region) then we can sometimes pay a fair price for such a bike, depending on condition and accessories (pre 2008 KLRs are preferred).
