who does european breakdown insurance for bikes older than 15 yrs
RAC/AA ??
tried them aa says its to old rac seems more car orientated
Talk to your insurer, when I had mine through Bennetts they offered breakdown as an extra, included europe and that was for a '98 bike.
I ended up using it a couple of times 
basically they have a directory of local contractors they sub it out to and imagine this directory covers europe too.
Worth a call.
HTH.
