Great plan, and great bike to do it on. I am on board with the 250, too. This isn't Dakar, but a leisurely trip there and back. Easy to work on (as you noted), and find parts for. Don't forget to call on fellow ADV Riders-- I just sent an SOS on my last trip and was welcomed with a shady place to change a tire, good company and conversation, and some good words of wisdom.
