Ducati Monster Forum

I was trying to find a video of a duc monster on a stand with engine running.  I am trying to hear the chain noise.  Mine is rubbing and the mechanic informed me that is Duc and to expect that.  What is the deal here ?  I heard a Triumph Bonneville ( cruiser ) on a stand and was so smooth and the same for a cbr 600.  Anyone care to explain fwhat is going on ?  ( My sprockets setup is not stock and I was wondering if that change cause rubbing to this extent ).   I realize I am not mechanical inclined but would like to understand.  I am about to have the  chain changed at some point soon and wanted to be sure of what to expect.

Mine rubs a little bit and it's not too loose. I just checked it recently. It's only a little bit though. If you're worried about, check your chain tension. I don't know all the models but on the dual sided swing arm models it's on swing arm behind the chain. As a very rough measure, if you rear tire is on the ground (not on a stand) you should be able to push up on the chain at the mid point and NOT have it touch the swing arm.

When you're checking your chain sag, remember that it's meant to be checked with the wheel on the ground (no stand). Oh yeah, if you're hearing the noise while it's on the stand and you're running it (I wouldn't do that but it sounds like you are) then the chain will most likely rub a bit since the chain slacks a bit when you put it on the stand since there is no ground for the tire to push against and create tension.

A 14t will cause more rubbing than the stock 15t as it is a smaller dia and brings the chain down onto the rubbing block/chain guide more. I noticed this on mine and recently had to go back to a 15t (long story). After going back I hardly notice any rubbing, only on full decel and when the chain gets a bit looser... As long as you are maintaining the chain (lube & adjust) frequently & properly, and the chain isn't showing signs of crazy wear or rust, you should be worried about it....

Well, if it's up on a stand there's more chance that it will rub.  The rear suspension isn't loaded with a riders weight, so the orientation of the sprockets and the swing arm are different when it's on a stand, than when it's being ridden

Are you taking it to Motohio in Columbus?  If so I would suggest checking out J.D. at

Only about an hour and fifteen minutes from C-bus.

Awesome guy and even better mechanic.  He'll answer all the questions you have and will not try and sell you something you don't need.  Plus his rates are a lot cheaper. I would recommend him to anyone within 3 hours.  [thumbsup] [thumbsup]

Thanks all.  Yep, I am due for a change but even when I had new chains I noticed that.  Explanation makes sense.  But it was strange that I did not hear the other 2 bikes I mentioned do that.  I want to hear another monster on stand and see if it does the same thing as mine to ease my mind I suppose.


Yep, I do like Hord Power a lot and have nothing but praise for J.D.  This time a buddy of mine is going to replace it for me and hopefully I will learn  (I am not mechanically inclined unfortunately)
