I have the pleasant situation where at 5k miles, the main bearing has gone Being quote for an engine rebuild as difficult to get to it etc - now that I've done a bit of digging , it seems a common problem on the 848's I've done around 2k miles including approx 50 miles on a track day. Unsure about previous owners usage of the bike. Anyone been here? Looked at some 2nd engines but they have loads more miles. Anyone have any advise? Can't believe that at this mileage it already needs this type of work.....just when I was thinking of upgrading to a new Duc! Sent from my iPhone using Tapatalk
Same as mine. They must have gone through a phase of using similar bearings. From probing another dealer, they used a mix of hard and soft metal and the hard metal rapidly wears away at the soft. Sent from my iPhone using Tapatalk
Currently going down the route of unsatisfactory quality. It's a battle but looking positive so far. Been quoted thousands for engine rebuild. Sent from my iPhone using Tapatalk

It's currently at a Ducati specialist - just can't help but feel I'm potentially being taken for a ride for the amount quoted. Sent from my iPhone using Tapatalk
I was told could be up to £4K if it's damaged other engine parts. Another dealer had 2 in for the same issue and reckoned they do them for £2k ish. I called an independent and they said they actually get them reground and it is a lot cheaper. Sent from my iPhone using Tapatalk
It is a massive job mate so going to be expensive. But I'd look on the bright side and while the engine is apart get it blue printed and balanced will be a cracking motor then.
Agreed. My concern is will it just go again? If its a common problem then how would I know that it's a part that has been rectified? Or hasn't it... Sent from my iPhone using Tapatalk
Problem seems to be across a range within that period. As I'm battling to basically return mine as unsatisfactory, I've done a fair amount of research and have found so many bearing failures. Although this is on the multi, they probably just throw in the same/similar bearings. It may be they changed the bearing used in later models so would be worth an ask.

Re-grinding the crank journals normally takes away the hardness off the crank, depending on how good this was in the first place. Going oversize bearings leaves the crank a little weakened as it becomes thinner than what it was designed for, especially if you are going to use it for track use. You therefore should use a reputable engine builder who can re-instate the strength back into the crank after machining to ensure that failure does not happen again. Good quality bearings from and independent supplier is the way to go. This is not a cheap fix but will ensure that your engine will be 100% and probably better than it left the Ducatti factory
I looked into this lots before I got my 848. Most engine builders/dealers I spoke to say it's down to the end float on the crank as much as anything. They also said that ideal track and road end float is different so what might last years on the road might not last on the track. The upshot was that the tolerance for the crank end float from the factory allowed some motors to be a bit too tight/loose and that damages the bearings more than anything else from side loads.
Crank end float is there due to the crank expanding in the journals and the casings. If excessive cranks float is beyond thermal expansion then problems will arise allowing the crank to move in the abnormal rotation that is allowed, causing excess stress on surfaces that are not designed for.
Surprise surprise, Ducati were not interested in helping whatsoever. Not the best 3 month ownership story in the world but I'm sure there's been worse. Will get the work done and sell the bike on most likely. Such a shame as I had been looking at a Panigale can't justify staying with the brand. Sent from my iPhone using Tapatalk
Same situation as me. If you fight it, you may do alright. You do have certain rights if you can prove the fault must have been present or developing at the time of sale. I think the treatment is disgusting and is why I'm never buying a Ducati again. Sent from my iPhone using Tapatalk
