I agree with GPMAZ. While I love my 2013 Roadster and had plenty of confidence in it to go across the united states and back, Central and South America are a completely different set of circumstances. I would not attempt a trip to Tiera del Fuego on any Triumph Rocket for several reasons and the primary would be the roads. The second is maintenance reliability and durability. I think he would realize it's the wrong bike actually, before he even got through Mexico, let alone Central and South America. Can't speak for the other Triumph models as I have no first hand experience, but I would be thinking along the lines of some kind of dual sport by Honda, Kawasaki, or BMW. Also research the Iron Butt site. It's bound to reveal statistically with bikes would be more likely to survive such a trip. Sure envy the guy though! Talk about a "trip of a lifetime", WOW!
