Peg Vibration

My guess is she's getting ready to blow!

Just kidding

Is the 14 tooth sprocket moving the revs into a range where it vibrates more. Try slowing down to the rev range you used to cruise at and see if it goes away.

The vibration is greater in Sport mode and it is less at lower revs. It obviously ceases completely when you pull in the clutch.

I'm wondering if the front sprocket might has loosened a bit to cause this.

I'm guessing the 14t is involved. Of course going back to the 15t would answer that. I may have to do that.

Agree that the sprocket change may contribute but the boots are also involved. If you were using a "touring" boot before, those typically have a more cushioned insole and track boots less so. You've just removed some insulation...

I did not notice this with my previous heavy rubber soled military boots.

But to be fair when I switched to the Dainese I did not notice this degree of vibration. Which is bad now. The soles of the race boots are firm and hard and do not really flex all that much: if you are familiar with race boots.

Actually, why don't I just go for a ride wearing my former boots? That might be smart!

I'll get back on that.

I took a ride wearing my original military police heavy rubber sole boots.

This did eliminate around 60% of the vibration I felt with the new boots.

Still, I'm wondering if going back to the 15t front will get me back to not noticing the foot "buzz" at all.

Feeling it is like the elephant in the room. You can never remember not feeling it.

Do all Multi riders with the 14t (or even the stock 15t) have this constant droning buzz sensation on the balls of their feet?

And why did I not notice it for over 15,000 miles?

I'm thinking that you've just got it in mind now so you wait to feel it. I've still got the stock gearing and put adjustable pegs on it (no rubber...sportbike style) and don't have an issue with it. Maybe let one of your buds or dealer ride it. Since you notice a difference then maybe something is loose. If it was the sprocket...you'd know that immediately.

You are correct in my "having it in mind". I will take your advice and have another rider see if they feel it.

TimOz said:

Did you do the chain and sprockets yourself?

I hate to say this because I say it all the time but I would look at the chain tension. 10 second test is to move the bottom chain row with a rag while the bike is on the side stand. If you can move it vertically more than about 15mm it will be too loose.

A new chain will loosen after a few miles as it "settles in". I would also expect that changing the sprockets would mean that the chain tension gauge will be very slightly incorrect.

The last thing you want to do is over-tighten the chain but it seems likely it is a bit loose. Put eh bike in the correct DES mode. Take of the rear guard and try to tighten it ever so slightly, ride and try again.

No, I am not obsessed with chain tension but I think these types of bikes are quite sensitive to it. My chain is well lubed and is going strong at 26K km. When it gets too loose, I can feel it as rough vibrations at touring speeds and I know it is time for a tweak.

I'm liking your thoughts on "chain tension". The reason is that (and I repeat) I never noticed this drastically different foot peg vibration for the first 15,000 miles on this bike.

Is it possible that it just didn't bother me for 15,000 miles and now I can't wait to get off the bike after riding it for 30 miles? I'm not buying that.

Even though Doug's suggestion that I have it "in mind" is very insightful. I do indeed keep thinking about feeling it.

One last thing.

As I sit here typing this response: after being off the Multi for four full hours, now, I still feel a tingling sensation in my ankles and feet related to this vibration!

I am hoping I can get to the bottom of this.

Are there any other Multi riders who are experiencing this foot peg "buzz"?

Dan, As much as i would love to sit here and type that this is all in your head ... .... it does indeed sound like something , or some things , have changed to create the vibration.

throw away the boots for a start ... what size foot are you ?

Click to expand...

It is not in my head.

I am feeling a very numbing, distracting vibration on the foot pegs.

So far it appears that nobody else here feels this "vibration buzz" on the pegs that I do. Or they do and it doesn't bother them. Or they haven't read this thread.

I am thinking that the 14t front sprocket has something to do with this. At least I hope so!

That means that I need to switch back to the 15t. Even though I would miss riding the bike with the 14.

If that doesn't change the situation then it appears that it may be all in my head....and not my feet.

In the meantime: I am squeezing my knees against the tank so as to keep the balls of my feet directly off of the pegs.

No other Multistrada rider feels this foot vibration?

Actually I would love to hear that nobody else feels this!

That might narrow this down a bit.

Check you muffler mounting bracket rubbers, one of mine was causing a intermittent buzz through the footpegs, as the muffler position flexed the rubber insulation in the mount deformed just a few mm and the outside retaining washers touched the muffler side of the mounting. I spaced out the large washer with a smaller diameter thin washer - all good now but I think the rubbers will need replacing at some point.

Will do!

Buckeye said:

One more thought: I don't know if you have a centerstand. If so...check to see that the rubber bumper is still in place. If gone...there could be some c/s vibration that is transferred to the frame/pegs.

On the list! Thanks!

Buckeye said:

Just thought of one other point that may need some embellishment. Earlier I said to check to see if something is loose. One specific item that can manifest itself in a lot of different sounds/vibrations is when motor mounts are loose.

The standard method of tightening mounts (if one is suspect) is to loosen all of them and them to retorque them in the order that is specified. I can't tell ya what order since I haven't had to do that but the order is nearly as important as is the specified torque value.

Motor mounts? Added to list.

EagleRider said:

Dan, your comments indicate the bike is at about 16k miles. First major service (valves/belts) for the new Multi is at 15k miles, right? Did you have that service yet? Either way, I'd advise you take that bike straight back to your service tech (authorized Ducati) and have them either recheck their work or perform that 15K service. if that increased vibration has anything to do with belts, you want it fixed ASAP.

15,000 mile was done and the bike checked out beautifully. Valves and everything. Spot on!

It was then that I went to a 14t front. That was 3000 miles ago.

To recap on this:

I have just started to notice this "peg buzz".

To be absolutely fair I will offer that it "may" have been there since I rode it out of the Dealer with 1 mile on it.

But I'm not buying that ....for a second Wanted to include it.

The newer boots may play a part in this. I'll go along with that....up to a point.

What I would love is for a few other Multi 1200 riders to tell me that they are feeling zero buzz (vibration) when riding with their 14t front mod: in (let's say 3rd or 4th) at 4000 rpms or higher.

That's what I would really love to know before I start analyzing this thing to death.

Tim suggested "chain tension". I like that. That can transfer vibration real fast.

Andrew suggested that I ride another 1200. That is really the way to go.

After checking all the other suggestions for worn parts, etc... the next step would be to switch back to the 15t. I might do it even though the bike is not as much fun with the 15t.

I've even added an inner rubber sole lining to the new Dainese boots. Helped a bit: but that is like taking an aspirin for a headache.

If I knew that this annoying peg buzz was supposed to be part of the ride I would learn to adjust.

In the meantime I do appreciate all of your mechanical suggestions that are far above my grade level.

I've had my 14t for probably 7 or 8k miles and notice no difference in vibration at all. I think you've already gotten good advice on what a potential mechanical problem could be.

Finally someone tells me they are feeling "no buzz vibration" on the foot pegs with the 14t mod.

Just to get this straight, Steve:

You are out riding the bike and your feet are firmly placed on the pegs and you are in let's say 3rd gear at maybe 4000 rpms..... and you are not noticing any foot vibration from the pegs?

You are aggressively pushing the rpms .....and your feet are feeling as if they are resting on the floor in your house?

Do I have this right?
