My main claim to scooter touring experience. Please note in 1981 there was a national 55 mph speed limit so a P200 could keep up more or less, though freeways weren't much fun. I have ambitions to repeat the trip or something similar but this was my first motorcycle tour where I went light and planned very little.
My advice remains to travel light, enjoy riding and talk about it after you've done it, not before. Don't over think and ride more.
