Tons of coast to coast USA motorcycle trips on YouTube ... I came across this kid who went from New York to California on Versys 650. Ten episodes but worth watching IMO ... this is the episode 1 https://www.youtube.com/watch?v=znl2suehyRQ
Anyway, good luck with your plans ... it looks like it will be an awesome trip!
Watching that makes me want to roll!
