Unlike the Route 66 trip, this will be loop instead of 1-way so it is not as critical to rent a motorcycle, but if you want to try something different or just aren't comfortable taking your bike that far there are options. A big rental company is Eagle Rider, who rents Harleys, BMW’s, and Honda Gold Wings (recliners on wheels). Bikes rent for as low as $50/day (unlimited miles) for smaller bikes.
