We highly recommend that you obtain travel insurance for the duration of your trip. Check that riding a motorbike is expressly covered as there are some types of travel insurance that exclude such activities. Accidents do happen and the costs can be serious if you do not have insurance.
We recommend Nomads Travel Insurance‘s Explorer Cover Package which provides unlimited cover, includes motorbiking and is very competitively priced. Nomads Travel Insurance has been voted as one of the world’s best travel insurance providers by LonelyPlanet.
