The fact that no one else's engine/frame bolts have sheared off or launched from Minneapolis into someone's eye 500 miles away would seem to suggest that the Panigale might not vibrate at some magical oscillation that renders surface tension between to objects null and void. My right nut (which might have been loosened by all the miles) is bet on this: someone ...... up the most basic of tasks. Bolts were improperly torqued at the factory. There's no ....... excuse for that. None. It's not an engineering issue, it's not a design failure. It's human error.

with a night of sleep

some funny feelings i had dduring the last couple of trackdays came to mind

must have set a new record for a stressed but non attached engine as a frame. 282 on the straight at Mugello.

no wonder she runs wide as the wheelbase lengthens and trail increases as soon as you get go off the brakes... :) and that the forks chattered under braking which we did not seem to understand why is now also explained...

But the more i look at the pics, the scarier if find them to be.. :(

Kope, as I said in a previous post, you really SHOULD email these pictures to Ducati. They need to see these. If only so as they can issue a mandatory recall or at least a service directive for dealers to check torques on the nuts and loctite them. I fully appreciate this might just be a one off, but I remember a similar "isolated" case when an early batch of Triumphs begun to snap at the headstock, in one case resulting in a serious accident, eventually prompting action. If your airbox had decided to separate from the cylinder heads, the consequences would be very ugly indeed. Ducati are surprisingly willing to discuss technical issues over the phone. I know because I have spoken to the factory recently over another matter. You need to email them first, and request that they call you, which they will. You'll find the relevant contact address on their website.
 
Hi topo

i ve given them to ducaati Benelux through my dealer and the respons was that when riding track, i should check them regularly... when i asked them if there were any other things i should know about that need checking, is was told to ask Steve.

apparantly the would have been a warning going out from Corse to check them but i m not on their mailinglist... yet.. :)

Steve is looking into this with a serious eye ... so i'll go to the appropriate channels .. I 'm sure Ducati wil value his opinion and he sounded worried when i called him today...

just to put some fears to rest : the front cylinder is still supported by the radiator that hangs on the frame and the front cylinder... ... :)

so le'ts see.. but thanks for you offer !

And i'm looking forward to riding that bike when stable... i'l prefer it over riding it with it's inbuilt variable geometry package ... lengthening wheelbase and declining rake...

Now there's an interesting bit of technology that, when intentionally implemented (ha), could prove very useful for optimizing handling under various conditions. I recently viewed a brief digitally rendered demonstration of the concept in action on the Kawasaki J Concept bike:

Who knows; perhaps Ducati's frameless design will someday enable this type of advancement.

i didn't complain someone else did i just commented. you did not see me write a post about complaining about my 1199. just the more stuff that comes out denial is more than a river in egypt.

So if I understand your logic correctly;

If complaining (the habit) was like a drug addiction (the problem), it would be considered OK to use other peoples drugs to get high (complain) so long as they weren't your drugs (complaints).

Now THAT is denial. ;)
 
Considering the importance of these bolts and nuts they should be secured with a cotter pin or retaining clip so they can't vibrate out like that.

Maybe if one is riding this thing to the max on tracks like a racer, then it would be prudent to do more pre ride checks on critical fasteners like a race team mechanic would be inclined to do on any bike.
Especially any and all fasteners that mount the engine to the frame with a big V-Twin engine.

Or alternatively a bit of Loctite blue would do the trick as a precaution for the rest of us.

I'm sure that DUCATI will get on top of it (if there's actually a problem) eventually;)
 
Kope, any news on this yet? Would be very interested to hear Ducati's feedback, since this could potentially have been, or may prove to others to be, a serious problem, that could lead to a very nasty accident. Not something, I imagine, Bologna would want widely advertised.
 
I had some odd chatter midcorner... Only thing not checked during the year is those nuts.

I will check then during today.

One thing I found loose is the bolt in the swingar, holding the suspension rod... Like one turn out....

Cheked....

Both in front very loose, damm it

Rear ok

Seems as if you have the same problem as Kope did, as unless I am mistaken both his front ones were loose/off completely. This is a SERIOUS issue and one that Ducati need to know about. As said in my previous post, were the other two nuts to have come loose, it could lead to catastrophic, even fatal consequences.
 
It will be very interesting to see how long they stay torqued down this time, I guess a reasonable service interval would be every 1000 miles?
 
I've been having a handling quirk where the bike seems to wallow(not feel planted or settled) in long corners, I've been chasing this for a few months via damping adjustments and have given up and decided to get ohlins sprung for my weight for the coming riding season .

This thread got me thinking that loose bolts could be the reason the bike feels weird. I plan on checking this and will update.
