My belt drive has damage (from a stone trapped between the belt and belt cover?). Has anyone else had this problem? I’m curious how much damage matters. Do belts ever fail?
Yes, it's the drive belt (I think a new drive belt £400 plus 2h labour). Though I've been told that a damaged drive belt rarely-if-ever fails.
I had a stone through my belt at around 1000 miles. My dealer said that the chances of total failure were very slim, but it wouldn’t repair itself so I had a new one fitted. Cost around £450 all in for the belt And fitting.
Here’s a photo of the damage to my belt. Once it was replaced I removed the guard to stop a stone getting tapped in there again. I fitted the Roland Sands front sprocket cover which is open. I’m now on 8500 miles and no problems
It's a freak accident for a stone-chip to get into there, considering the belt is what 2.5inches wide. I wouldn't worry about it but you could ham-it up for the dealership to replace it via ducati. However that part is a subject to been a consumable part I beleive.
