rico, no need to get too worried about this. If you know the original owner of your bike, ask him how hard it was ridden. If raced (constant high revs), get the chain removed and inspected for wear. Work out how far the tensioner has moved, and how much more it has until it hits the stops. That will give you some peace of mind.
The chain and moving guide must be replaced at 25,000km intervals, so yours is coming up to that point (mine also). Not many have been replaced yet. When that starts happening in numbers, the full story will be revealed.
Another thing to think about - if the dash has been replaced (maybe several times) the odometer will not show the true distance travelled.
In my humble opinion, the chains that broke were worn out - but I'm no expert, and haven't access to all the evidence. Just how that could happen when the bikes have only done 5 - 10,000 kms, is a mystery - but there may be more to this than meets the eye. I do understand that the moving guide on one of them was fine. It was the fixed one that got mashed up as a result of the break, not the cause of the break.
