isnt 'pillion insurance' part of the bike insurance so the passenger is covered the same as if in a car (assuming that the rider has taken the pillion option)..
thought the original post was more about the travel insurance side of things as most policies wont cover you if you are injured whilst travelling on a 'bike' - blame the drunken bods on mopeds in majorca for that
so you wouldnt be entitled to the repatriation and other extra bits that your travel insurance covers, and would have to take your chances with the EU medical card or if outside the EU pay for it yourself.. just been lookign into this as am going on bike hol to US this year so standard travel insurance wouldnt cover it. Did mine through Carol Nash.. went for the yearly policy as also covers you whilst on 'holiday' in UK..
