World Nomads doesn't sell third party liability (the insurance which pays when you hit someone). That's the kind you'll find available as you go from country to country. In most places you will not easily be able to buy the array of other insurances which are available at home.

World Nomads sells travel insurance. The exact policies sold vary greatly from country to country and, in the USA, from state to state. That makes these endless discussions go around in endless circles.

If you buy travel insurance, read the fine print carefully before paying. There's no way to predict what it's going to say--about motorcycles or anything else--without reading it. And did I mention "carefully?" They don't make money informing you in simple language about all the reasons you shouldn't buy their products.

It should go without saying that what an agent tells you over the telephone is worthless in the absence of an actual written policy confirming whatever rash promises he/she made.

When asking questions about insurance, try to distinguish between repatriation insurance (medivac, to get you home when sick or injured), health insurance valid in your home country, health insurance valid wherever you go, insurance which will buy you a new bike if you drive yours off a cliff or it gets stolen....and third party liability, which most people purchase at borders, if at all.
