Thanks for the follow up, Scott. I did some online research right after writing my post and found motocycle rental companies both large & small, international & local. I had read many years ago about a company that specialized in European motorycle tours and that company was all-inclusive in that you chose a tour route (and there were many) and a bike and they take care of all the details such as accomodations, maps, restaurant suggestions, & things to do at various stops. It seemed like a very cool way to take a vacation.
My current goal is a sport tourer for fun and commuting since we have six or more months a year to ride here. The Bimmer gets about 22-23 mpg on the freeway so a bike that gets 45-50 mpg would cut my fuel bill almost in half.
