Worst case you crash. You are either in a group or riding solo. In a group you end up with one person, and there will always be one, who can and will ride to the nearest town to get help. However, you are asking someone with a very high sense of urgency to ride alone in a remote area to get help, and they WILL take more risk with their speed and riding style to help you. This is a recipe for trouble. In my opinion it is not the best idea to separate the group and you never want to have someone ride off alone with that kind of responsibility and sense of urgency and again without any communication.
Another scenario is you’re alone. You crash and you need help. This really is the worst of the worst-case scenarios. The reality is comms are the only thing that can help you. With a device like a Garmin In-Reach or SPOT Tracker you can contact emergency services using the SOS bottom as well as loved ones in the event of a crash. This is priceless in a situation where you won’t be able to get yourself to the nearest town for medical care or help.
Riding remote off the beaten tracks is rewarding and here in Patagonia is no different. The rewards for adventure motorcycle riding in Patagonia far exceed the risk but having that one link to fall back on is never a bad idea.
