Hi... I am from Colombia and i am planning a 1.5 year RTW trip with my son in two bikes, we would like to ride on country roads as much as we can (avoid pavement whenever is posibble). The trip will be something like this (Still planning): - Sudamerica: Colombia - Buenos Aires - East Africa: Cape town - Spain or Italy - Europe to Vladivostock: Russia, Kazajastan, Mongolia. - Alaska to Colombia. We have been thinking about these bikes: 1) KTM 1190 adventure R (I fell in love with this one) 2) BMW R 1200 GS, I have a GSA and i am concerned about the reliavility for a long trip. 3) KLR 650 4) DR 650 5) BMW F 800 Which one would you recomend and why?
