Awesome and succinct ride report.
I am reading this at an outdoor cafe on the beach on Costa Rica, eating mystery meat papusas and drinking duple espressos con leche.
I am seriously considering not shipping my KLR down to South America next year, and just bringing soft bags and buying a 200/250 in a local market and using that. I could buy and write off the whole bike for the price of shipping a 650 to and from.
Very cool endeavor that you three pulled off. I am sure you will hear terms like "inspiration" quite frequently as this thread develops. Whether you meant to or not, you've definitely shown that the spirit of ADV riding is not only for the young or displacement-happy. Ride well, and thanks for sharing!
