For all Ducati know, you could have left the bike out in your front garden between the first service and when you had your accident. The brakes could well have seized or the pins corroded, or vampire mice ate the brake lines, or anything to cause the brakes to lock as they did. This is why they are taking so long to check everything.

So does it state in the handbook that "this vehicle must be garaged at all times in a humidity controlled environment"??? This is a vehicle designed to be used for transportation, in all weathers if necessary. If leaving it outside in all weathers for a few months (which I didn't!!) caused such a problem, it would not be "fit for purpose" and therefore I would entitled to a replacement or refund.

There is a section in the owner's handbook about pre-ride checks, and this is their Get-Out clause should something like the above have happened and you didn't check it before riding, as it is your responsibility.

Am I supposed to strip and rebuild the brakes before riding then? That's a new one on me. Does anyone else do that?

I think Ducati have been very generous so far in offering to replace everything to get you going again

They have been generous, that's true. However I want to know what the fault was before the bike is repaired. It could be a design fault, they could put the parts on and I could have another accident. I don't think it's unreasonable to want to know what the problem was before having it fixed.
