This is the approach I'd be using if I was in any doubt about the integrity of the original assembly. Unfortunately I'm away from home (again) and can't check it but fortunately I'm supposed to be a mechanical engineer so I can have a look and see what things look like when I get home again. I don't want to get involved in any slagging matches but I appreciate the heads up so I've got the opportunity to have a look at it.
Thanks for the info and photo's Stu. Can I say in relation to your question, your contract is with the supplying dealer and as such they have a duty of care to you. The bike which you purchased from them should be fit for purpose that is road worthy and mechanically sound. However roadworthiness or lack thereof is a hard thing to prove in that it could be argued that the bike was roadworthy just before the wheel fell off or the engine fell out. General wear and tear lack of proper maintenance hard riding and handling can all be used as weapons in the I don't want to deal with the situation armory. I cant imagine given the severity of your situation that your dealer would not want to investigate the cause of the problem and rectify it. However I presume after your experience that you have lost all faith in that bike and hope that your dealer and Ducati look after you. Best of luck.
silly question Edward, do you do pre-ride checks? surely it hasn't crept up, and would have been felt through moving the bars around? Pre-ride on centre stand
Depends what you mean by "Pre Ride Checks", tyre pressure and chain tension get done once a week, bike gets washed after pretty much every run out, which means getting up close and personal as your washing and drying, oils and fluids and a good once over. I didn't notice anything untoward when I left the house and I did 100 straight line motorway miles which would not have highlighted the concern. It's only when after those miles I went to filter through stationary traffic which meant a bit of swerving that I noticed pretty quickly. I've just returned from a 2500 mile round trip to Italy and nothing fell off or broke. Like I mentioned in my above picture filled explanation, all I do every day is mechanical and electrical engineering activities so if anything is out of place I will usually find it, and I found it immediatley after I got the symptoms of flat tyre / head bearings. A quick visual for future reference would be that the thread is pretty much flush with the top yoke, if any threads are showing then the bolt is on it's way out. But it's not an indication that the bolt is tightened to the correct torque, so be aware.
Just looked in the parts manual and it lists the part as a "pin" and the part number is 821.1.329.1B It's item 33 on the below parts breakdown.
An informative post, thank you for sharing your find Glad it wasn't any worse Pity some people mock it!!
A quick update regarding my issue. Popped into M&S Motorcycles this afternoon to drop off the red key and was informed that the "Pin" is supposed to be threadlocked. So, missed operation on my bike maybe. Unless you have a mirror on a stick and a torch it would be difficult to tell, next time i'm in M&S I will take my mirror and torch and inspect a few to see if indeed the threadlock is visible. I also have another theory why it loosened off apart from vibration but the wife has shouted me for tea so it will go up later. Cheers Stu
Thanks for all the information Stu and for putting on such clear labelled photos Good for those of us that don't know what end you should hold a screwdriver! It will be interesting to find out if Ducati send out a service bulletin or just leave it as a freak incident.
Great warning post Stu. I'll definitely be checking mine as should everybody else. Appreciate the forensic pics too, really helps. Faaaarrrrkkkkk.
Thanks for pointing this out. This is a good post. I've checked mine and I can't see any sign of over spill of thread lock, however it's been in for 25K miles so it aint going anywhere. I think you'll find a few opinions on here that don't always mesh well, especially after a scare. Given the amount of cable drag on this bike going lock to lock you'd be hard pressed to notice this during a straightish journey. It might have started to feel like headstock bearings before it finally "set you straight". Don't forget the bars hardly move once you are above 30MPH. The wear shown in the photo could easily of occurred during one journey, so a pre-ride check may not have noticed anything. Very scary and yes I agree not designed with failure in mind. A bit like the front fork foot. Note if you fit the Ohlins steering damper you can't even see this bolt!
Thanks for posting this. First thing I did was check all the bikes we have in (new and used) and none seem to have anything remotely like the issue so that's good. To help put everyone's mind at rest, we've sold over 170 new (and a good number of used) Multistrada since launch and we've never seen or heard anything remotely like this happening so hopefully it's an isolated incident. We'll keep an eye out for it nevertheless. Main thing is, you're not hurt and the bike is easily repairable. Hopefully when it's secured correctly and the rest of the parts replaced you can just put it behind you and move on. Mart
