Your RR is definetly inspiring me! I have read lots of blogs and sites about South America trips but never found details about how much it costs. Now I know it's possible to travel with a limited budget. Thank you so much.
I stick with you at the minimalist philosophy. In fact I have gone in some trips here in Brazil with my little ( but "muy macho" ) 150 cc Honda and I know for sure that the motor size isn't something that can prohibit you to travel.
Unfortunatly I can not offer a gas tank for you (at this moment, at least), but if you decide to know Brazil's capital, you already have a place to stay.
