Serious Safety Issue on a 2009 Monster 696

[Speeddog]

I looked a good bit closer at the pictures, seems the retainer plate lost the teeth.
Not 100% sure, as the pics aren't the best for that view.

I've got 40k miles on my OEM retainer.

Thanks for all the info folks.

Hopefully this will be resolved before winter.  It is a bit reassuring that this is not seen very often and i'm glad it is only mechanical damage. I posted because I would not want this to happen to anyone else just in case they would not be as fortunate as I was.  I don't have a lot of riding buddies nearby to talk shop with, so even though this is my second bike since 2002 I really only have a superficial knowledge about motorcycles.  I never would have thought to check the front sprocket hidden underneath the cover. 

I guess this is a wakeup call to really pay attention to all the minutia.

You would also be able to see the rub begin on the swingarm.

I also would not necessarily consider this a "serious" safety issue.

yeah i would like to see the name of the first post changed so as to not set off a panic button to searchers and first time readers.

The consequences from this could have been dire and hence this is serious. Also, no one out there would like to have their ride damaged like this especially if it is "preventable" like many of you seem to believe. I check the tire pressure and measure chain tension weekly never noticing any rubbing on the swing arm during these checks.  I suspect there are others out there like me who didn't even know that this could happen what ever the reason (which hasn't been identified).  Maybe I was riding along ignorant of an issue smiling because of the fun I was having.  I suspect that most of you out there were unaware that this could happen as well.  Some of you think this is human error (on my part even) but if there are others out there like me, they should be  aware of this issue as it could be serious.

[snip]  I actually prefer the plate/spline/bolts sprocket holding mechanism over a tight bolt on the splined shaft.

Amen to that

point is this isn't a serious SAFETY issue, it's a serious Mechanical issue on YOUR bike, not all 696s.

Hi All,

I wanted to inform the Monster community of a serious safety issue that occurred on my 2009 Ducati Monster 696.  ...

right raux thats what i said "my 2009 ducati monster 696"

[junior varsity]

I'm not even sure I'd consider it serious. Its an issue, sure, its unfortunate - absolutely, and it has made a mess. Serious to me is an issue with brake failures, an engine seizing, catching fire, giving crabs, etc.

DID 520 isn't a stock 696 chain is it?

[mikesmithmjs]

I'm under the impression that everything is stock because the dealer never said anything wasn't stock except the frame sliders and a stick on tank protector.  however impressions can be false.

the bike is still at the shop, i'm still waiting to hear if this will be fixed under goodwill so i will have to count from the above photo.  There markings i can see show "Z45 02/08"

DID 520 is indeed the stock 696 chain.  100% sure.

I'm under the impression that everything is stock.....

And that for sure is also the stock rear sprocket.

I cant wait to find out what is found.  Things just look wrong!    Why is the sprocket and shaft covered in rust and everything else is covered in lube?  You would think a little bit would have found its way there.  And the teeth on the front sprocket are way too worn to have so few miles.

[battlecry]

Mine spurts a little rust from the shaft splines and plate lock notch.  The mechanisms are subjected to cyclic stresses, corrosion/fretting is common.  I wouldn't worry about that too much.   I don't think that area can be made pretty if you ride the bike.

What is chain freeplay, with & w/o rider?
