Bought a used 2017 Ducati Scrambler Icon, 8,500 miles on it. Stock chain, DID logo on it. Chain broke as we were picking it up. Previous owner kept the bike well maintained, and had just got it back from being serviced at the local Ducati shop. Shop guy mentioned that it needed a new chain and sprocket, but that was it.
Photo 1 is broken pin. Broke in the center, this is not the master link.
Photo 2 is inside the barrel, in the center you can see a defect, a ridge in the center, which matches up to where the pin broke.
Photo 3 shows the beveled edge of the break. It appears that the defect wore a groove into the pin, that caused it to fail. Luckily, it happened in the driveway, and not on the road. Has this happened to anyone else’s chain? Just wondering if this was an exceptionally rare occurrence, or if this chain is known for defects.
New chain was installed, and I've been a happy Scrambler rider!

DID chains have a long history of excellence. It's reasonably uncommon though not impossible for any manufacturers' chain to fail. Sadly, if the chain was maintained too tight, that could easily have been the cause of the linkage failure, not to mention requiring a sprocket and counter sprocket at 8K miles. Plus, purchasing a used bike, one never knows about the maintenance history, even if the vehicle was "well maintained". So do your research on purchasing a new chain, sprocket(suggest steel) and counter sprocket(suggest steel), maintain the chain tension per Ducati's recommendation, keep it clean and lubed and hopefully you'll avoid having that unfortunate experience again. P.S. your Scrambler was not designed to leap tall buildings. Keep the shiny side up.

Good to know about DID chains. My Ducati/Cagiva Alazzurra had a different brand chain, and had zero issues in the 20+ years that I owned it. We showed this DID chain link failure to several mechanics and they've never seen any chain break like this. Sprockets have been looked at and passed inspection. Chains and sprockets are routinely cleaned and lubed in this house. Not planning on leaping anything, but may pop over a log or two! Happy riding.
