Just a word of warning!!. On our trip to Spain last year where my 100gs broke down, I contacted the RAC service provided through Bennets. Service was fantastic with English operators based in France.
.......Moral of the story, Bennets, Carol Nash or any others only sell you the policy. make sure you have a get you home policy and check that it covers a second or related breakdown.
Good advice about checking the details, there is nothing more expensive than cheap insurance that doesn't pay.
Just out of interest, what is the age of your 100 GS and what is / was the age limit in the RAC recovery cover you bought, via Bennet?
Most breakdown policies have an age of vehicle limit in them, for obvious reasons. This makes it tricky if some customers have a single multi-bike policy (old and new bikes) but one single breakdown cover, linked to just the single policy number.
It's quite possible that just the younger bike has the breakdown cover, not the older one, but that may not be too obvious. I have seen it happen, quite innocently. A friend had a four year old R1, with Europe wide breakdown cover bolted onto his normal insurance. He then, after a few months, asked the broker to include an old Honda 4 - 400 bike onto the same policy. This went OK, the additional premium being just a few pounds. Only afterwards did it dawn on him that the Honda was too old for the breakdown cover part....this sunrise moment came on the A1, in a lay-by and it was very chilly.....
Most European breakdown policies will give a subsequent or second breakdown - especially if you have bought an annual or multi-trip cover - though they may limit the total number of claims you may have in one year.
This is little different to the annual vanilla AA / RAC / Greenflag UK cover which may have a limit, too. I guess it's to stop people being lazy and simply asking the recovery company to take them home / repair their vehicle every 10 minutes of the day.
If, however, you bought a single trip insurance from the RAC, it may have a single claim limit in it, which you might have burnt up when the bike was taken to Tours. Nor is it clear whether the second breakdown (overheating) is linked to the first problem (cause unknown). Or whether, whilst repairing your first problem, the Tours garage caused another problem, or quite what happened.
Let's say, for example, your first problem was caused due to a faulty oil pump. The garage fixes it, you pick it up, and ride away...quite happy. Then, 30 miles down the road, the bike runs like a bag of spanners, or worse, as matey in Tours forgot to put more than a drop of oil in it....what might happen then?
The devil, as they say, is in the detail.....
I'll be honest, I am not a great fan of 'bolt-on' covers, sold bundled with motor insurance. They are lobbed in, sold and bought without too much thought, getting mixed up and not read, when all the punter really looks at is the premium on one day of the year. They may be a little more expensive but separate, annual, cover is often better value in the medium / long term.
