a mate has a S2R 1000, it's just 3 years old and at it's 20k service he was informed that there are 1 inch cracks in the cases at the rear engine mounts on both sides.
i'm curious to see if any members here have had the same problem and if so how was your dealer or NFI about it? being out of warranty may be an issue but here's hoping there's some good faith like when the 900SS frames were found to crack at the weld around the steering head.

Has he had it since new??

yep. he's in his 40's rides sensibly, no wheelies, never crashed it.

Hmmm, maybe thats the extra movement/noise coming from my clutch area?? 

The basket etc is only 20,000k old, (original basket/plates replaced at 23,000k ) and there isnt a lot of movement in the basket so thats all still serviceable, but the hub hasnt been done!! 

So I just wonder if the cush drives in the back of the hub are just about "Jatz Crackered"?

Time for a good look (and the rear mount area) , as the M1000S DS is an S2R's slightly older brother I guess.

I better check my bike!

Have you got any pics?


Rob

Some pics would be great.

So now we have to replace the cush drives/rubbers at 20000k's now?

I think when I get a new set of sprockets and chain I'll replace them then, I've just clicked over 20000k's and my Cush drives/rubbers still appear fine.

Does anyone other than a dealer sell the Cush drives/rubbers?

the rear engine mount supports the rear frame weight as well. has he overloaded the bike? maybe that could be the cause

or overtorqued engine mount bolts?

This has surely got to be a rare issue though?
I have only ever heard of this on a couple of other bikes, usually from contamination/fault during the molding process.

This is about the 20th odd bike I've heard this happen to. My own 1995 M600 happened the same thing after 45+000K's.
Several US people have reported the same thing. But were talking 1 in every 1000 bikes at most, not common, but not unheard off either.
It IS repairable and the engine mounts can be re-welded. Sometimes still in the frame if the welder/tradesman is good.

From discussion on the old board, I think there's more suspicion aimed at under torqued mount bolts - the movement allowed if the bolts are loose could be what cracks the castings...

Like Sydmonster says, it's not _common_, but it's far from unknown...

bazz is referring to the SSS bikes that have a problem with the cush drive rubbers separating and the outer backing out from the rear sprocket and rubbing on the swingarm and eccentric. your DS being a normal swingarm is imune from this particular problem, but not from the cush drive rubbers actually tearing, that said, i've seen them last 100k in an SS.
no pics yet, we're riding this weekend so i'll get some if i can.

Hi guys.
I'm the poor bastard Paul is refering to. Just started surfing the web to find out if this is a common problem. I will post pics tomorrow for others to check their bikes.
Thanks for starting this Paul, appreciate it.
I'm taking it to the dealer next week when I get a chance with a view to Ducati doing hopefully the right thing.
I don't flog the bike. Its never looked like going down and don't wheelie it or even pillion it so am at a loss as to how and why this occurred.
This bike gets better looked after and pampered than my kids.
Bevan at Eurotwins said this can happen when engine mount bolts are lose. Mine were not as the fault was discovered yesterday by him doing the 20000k service.

Been told the fix is to drop the entire engine out, strip it down, get it welded and re-painted then re-assembled. Cost from $1300- 1500 all up.

cheers

stick too your guns pju ive done some kicking and screaming about cush drives backing out on my monster and chewing the eccentric hub my local ducati now admits that it is a problem and has fixed one bike out of warranty all ready so now there looking into fixing mine
