I once used BMW Motorrad Roadside Assistance to rescue my bike.
I was going down to Devon one Friday evening, when I noticed rain coming out of cloudless sky as I was going up Telegraph Hill on the A38; odd, I thought. I got to where I was going and parked the bike up on the road. Saturday morning, though, I noticed a pool of fluid under the bike - the radiator had sprung a leak and deposited its contents onto the road.
So I phoned the magic BMW number and spent about half an hour passing over my details. They agreed to come and collect the bike, take it to my local dealer in Hertfordshire, and give me a replacement vehicle for a few days. About a couple of hours later some guys tipped up to pick up the bike and drop off a BMW M3 - there weren't any replacement bikes available .
On Sunday I drove home in the car. Quite quickly. On Wednesday, I got a call from the dealer to say the bike was mended, so I drove over, picked the bike up and left the car there.
I still pinch myself that it was all that simple. It's not a completely fair comparison, as it all happened here in Blighty, but if it works anything like that when you're abroad it going to be about as nice an experience as you can hope for.
