I'd still be concerned that something happened and there was no valid insurance in place. Losing everything in a lawsuit isn't high on my list of fun vacation activities. If twisted road doesn't provide insurance as part of their service, I would look for a different provider (especially given the reasonably steep prices they are looking for).I'm not looking to rent my bikes out.
I'm looking at this as a rental option.
Insurance companies always ask "will you be renting it out or using it for commercial purposes". There's a reason.You better have a commercial insurance policy if your getting involved with this. Your personal policy will be voided the moment they find out you were renting your bike out. If something bad happens to the rider while renting your bike... You will be sued... and have no insurance. It'll be so much worse if the rider also injures or kills someone else while on your bike.
