Read The Words
What's interesting is that the reluctant author is telling us NOT to do it on a 250 if we can help it! I crossed the US years ago on Vespa but I took six months to meander, at a time when the double nickel was the speed limit and i was young and obligation free.
Sometimes I am tempted to think a small bore tour would be fun, and I am forced to wonder at age 54. I have crossed the country several more times and remember my 650 Maxim as perhaps a good compromise, shaft drive fairing and bags included.
I see not much fun in doing it Goldwing style so perhaps there is a compromise closer to the ideal? A modern 650 single by BMW or Kawasaki? A Tiger 800 or my Bonneville? Not perhaps the Suzuki TU250 of my fantasies? I hope I heard the man who wrote the abbreviated story.
