So i'm planning a trip to Alaska to deadhorse with my girlfriend. We given ourselves over a month, we're leaving from New England, that should be plenty of time. Together we weigh a little over 320 lbs + camping gear, I need a bike that can handle our weight on the highway and can do some light railroading. We're both broke university students so I was thinking something on the cheaper side, Vstrom650. I need a bike that can handle highway speeds with our weight, I hear the weestrom gets blown around. Not too sure if there are any good alternatives for something around $4k. What do you guys recommend?
