Yes, we highly recommend and it must cover you for riding motorbikes of 250cc or more. Travel insurance for Thailand even including motorcycle cover is not expensive and will offer you many benefits if you need to claim. Riding anywhere in the world without adequate travel insurance is lunacy and obligatory on all our tours!
People from 43 countries around the world are able to get a free Visa on arrival at the Suvarnabhumi Airport (Bangkok) including EU countries, Australia, Canada, USA and New Zealand. The visa is for 30 days and very easy to do on arrival. Just fill out the form and give together with your passport to the immigration officer.
But if you are planning on staying in Thailand longer we suggest applying at your local Thai embassy for a longer visa. When you apply to join one of our bike tours, we will advise you on visa regulations.
