Have other on this forum experienced front brake rotor warping on their Scrambler? You know, where the front brake lever pulses or you can feel the shudder through the handle bars when braking?
Over on the other Scrambler forum there have been postings about owners experiencing warped front brake rotors without many miles on the bikes. Disk warping issues? | Ducati Scrambler Forum Some with a few as 800 miles. Mine began exhibiting warped rotor symptoms at about 2,750 miles. The symptoms have gotten progressively worse up to the current 3,500 miles on the bike. Ducati does not warranty brake rotors in the USA claiming they are a wear part. My dealer told me to bring the bike in and they will have a tech ride it to confirm the symptom and then they can assist me in asking Ducati Customer Service to "Good Will" a replacement rotor.
I completed a customer contact form at Ducati and the following is the result of that effort:
Well, this morning I had a telephone call from Fabiana at Ducati "customer service" (tel # 390510938001) regarding my complaint filed through their contact form. (She was persistent as she called three times trying to reach me) They called all the way from Italy, kept me on the telephone for 15 minutes and that time was spent repeating over and over, in a slightly different way each time, that I would have to do what I had already been told, which was to take my Scrambler to the dealer (250 mile round trip), have them evaluate the issue and then they could assist me with reporting it to "customer service". Once Ducati "customer service" had that information they would decide what, if anything, they would do and if they were going to replace the rotor I would have to bring the Scrambler back to the dealer (another 250 mile round trip) to have the service completed! Guess Ducati would rather spend money making international calls trying to make me feel better about Ducati instead of replacing defective brake rotors (which would really make me feel better about Ducati).

I suggested that perhaps Ducati could inform my dealer that should they verify the warped rotor they could then replace it without making me spend another full day returning to the dealer to have it replaced. She only repeated herself yet again with the same litany of two trips will be required. Now you understand why I am placing quote marks around "customer service".

Fabiana, the woman who telephoned me responded to my question of why she called if all they were going to do was tell me what I had already been told (and included in my customer contact form) said something to the effect of "We telephoned you because you filled out the form and we wanted you to feel better" i.e. nothing to offer, Ducati just wanted to try and make you like us. Guess Ducati did not want to put that in writing which is why they telephoned. In all Ducati wasted 15 minutes our of my work day and only served to make me even less pleased with Ducati as a company.

It will be very interesting to see how this all plays out. Stay tuned.

In my own experience it's hard to warp car or motorcycle rotors. My Harley was shuddering when I was braking (has dual front floating disks) and I solved it by cleaning the 'buttons' with brake cleaner and a lot of patience. The previous owners never cleaned them and the bike probably lived outdoors.

Have you checked the buttons on the Scrambler to make sure you can make them move with your fingers? Keeping the 'floating' aspect of the rotors in proper operation will hopefully mean no shuddering. They may very well be made from sort of bad metal though. I'm just throwing it out there as something free to check before wasting time at the dealership.

A good cleaning and making sure the buttons turn freely.

Hello

I'm the moderator an Ducati Sport-Touring mailing-list, in France (approx 400 members) and we faced several front rotor warping issues. Many of them have been taken in warranty.

Another reason for this strange feeling you describe can come if one the pushing rod in the calliper is not working properly, mainly due to dirt and bad cleaning of the brake callipers. Perform a deep cleaning of the calliper, ensure the rods are moving slightly and you may suppress this feeling.

One last action you can do is to put some high temperature grease (copper grease) on the ***backside*** of the brake pads. This will avoid some vibrations in the brakes and suppress this feeling.

I also have this problem. I don't remember when it started to happen but I think it was maybe around 4000-5000km. During my 12k km service they kept the bike for 3 days to check it out and said they cleaned and adjusted the rotor and brake and it definitely made a difference but the pulsing is still there. I'm pretty sure it's warped but I already had so many problems that I'm tired of getting them fixed and am now thinking I'll just live with it and hopefully a new rotor wont be too expensive once the old one is used up.

But this is definitely an issue that quite a few people experience.

Maybe these rotors were never ment to be used alone? They usually have them as dual rotors on the other bikes. I'm sure having only one rotors puts a lot more stress on it.

Hello


It's very easy to see if your rotor is warped or not. Just lift your front wheel from the ground, use a plastic card (like a bank card) to push back both pushing rods from the brake pads and spin the wheel. If the rotor is warped, you'll see it approach the pads on some angles of its rotation. It may even, if it is severely warped, touch the pads on some angle and stop.


You may also remove the brake calliper from the fork footleg and place a tool against the fork leg that just touch the rotor, to measure if, on some angles, the rotor goes away from the tool.


If you find it warped, check the pieces that link the rotor to its center part. These pieces should be able to move. If not, you need to release them.

Its not warping, we have a floating disc setup and the buttons are probably jammed. Clean them with a brake cleaner spray and then make sure EACH ONE of them rotates.

One way to do it, is to take a few washers, take a 6 to 8mm screw and nut, put washers both side and tighten it till the button starts rotating.

Do NOT use any lubricant spray such as WD40 etc.

Are you sure it is not the Anti-Lock kicking in?

Does it do it when you brake very easy or just when you brake hard?

Mine is warped - confirmed by dealer there is a runout of 0.25mm. But they reckon Ducati (Australia) won't cover it under warranty and quoted me $695 to replace it. An email to Ducati Australia about a week ago has also not been replied to. It caused me to get air in the lines (this was at about 4000km) and I had them bled. I then did a big trip over Xmas, long rides so not much stress on the front brake in that time, and when I got back I noticed the vibration and had the dealer check it. That was at about 7000km. Really not happy with the response from the dealer, owned by Ducati Australia, or the lack of response from Ducati themselves.

In 2006 Triumph had major issues with front discs warping. They replaced the one on my Scrambler 3 times under warranty up until about 18 months down the track whereupon I fitted an aftermarket disc and it was fine after that. (Metalgear)
Ducati should replace the disks because there is evidence they are defective. Triumph did.
Tell your dealer you'll keep the $695 and spend about $200 on an aftermarket one sourced online and fit it yourself or given their attitude, look into finding a private workshop to do this and all the future servicing.

Yeah, will probably end up going that way. Just waiting to get a response from them to say they will or they won't either way. Can then chase them up via consumer tribunal for selling a defective product and not providing required support to fix.

Some additional information:
Here is a link for USA owners to file a complaint with the NHTSA (National Highway Safety Administration) https://www-odi.nhtsa.dot.gov/VehicleComplaint/ If enough complaints are filed it may spur Ducati to do a voluntary recall rather than be forced to do so.

Additionally, post this thread to your Facebook or other social media pages and tweet about it if you use twitter etc. The more public the information is the more likely Ducati will take more action that a telephone call to see if they can make us like them more. If enough bad press gets out and sales volume starts to drop maybe Ducati will take notice. I also agree that if there is no manufacturer resolution of the defect (other than to telephone me and essentially tell me to not rock the boat) then I will source an aftermarket rotor (and not from any company associated with Ducati).

As of now my next bike will NOT be a Ducati. Unfortunate indeed as I had planned on adding a Multi to the garage.

Regarding some of the suggestions (thank you for your thoughts on this) made:
The "buttons" are not "jammed". One of the first things I checked, along with the caliper functioning. My Honda GL1800 (960 lbs - closer to 1,300 fully loaded) has floating rotors as well and with far more miles on the bike there have never been any issues either with the floating of the rotor or warping. I ride the GL more like a sporting bike (have dragged a peg or two) so the rotors are not subject to "light duty". The Scrambler is used on road (paved) only (just as with my Honda GL 1800) so dirt should not be an issue and was confirmed with my initial checking of the calipers. As a hobby I restore old motorcycles, going down to the frame and rebuilding so my mechanical experience and knowledge are well beyond "shade tree" level.

Update: I had my front rotor replaced under warranty yesterday. After hearing nothing from Ducati Australia for over a month after twice trying to contacting them via their website, my husband posted several times on their facebook pages. 24 hours later, they decided to make an exception and repair it under warranty as we are new Ducati Scrambler customers (aren't we all?).

Squeaky wheel gets the grease! Good for you. Now up to Ducati to fix the crappy rotors they sold to all of us. Never had any such issues with any of my Honda, Kawasaki or Yamaha bikes.

Thought maybe I noticed it last ride, yesterday left no doubt. Think the bike's kicked over 3400 miles or so. Where'd I read Ducati used cheap steel for these bikes? If that's so, I definitely don't want a direct replacement.

Sarah, over the weekend I had my dealer ride and inspect my front rotor. They confirmed it is out by 2 thousandths and have recommended replacement. I emailed Ducati customer service on Saturday and will be calling Ducati North America once they are open. I'll post the results. BTW, only 3,600 miles on it when inspected.

Thank you for the update, Tom. I believe there's been a report of an owner's second rotor warping, so I'm not so sure I want a factory replacement. Please keep us posted.

UPDATE: After leaving multiple messages at DNA Customer "Service" telephone # 408-253-0499 (actually the DNA general number with hard to understand messaging) I have yet to receive a return call from the gods at DNA. I say gods because they must believe that is their status or they would at least have the courtesy to contact me so I could "feel better".

My dealer has been absolutely great through all this, doing everything they can within the limitations they face.

It is DUCATI NORTH AMERICA that doesn't seem interested if I remain a Ducati customer or not. I simply do not understand no response. At least they could have the courtesy to contact me to tell me to go scratch. Although I suppose ignoring people does eliminate customer calls (AND CUSTOMERS) as most people will eventually give up. If San Jose California wasn't so far away I'd pay them a visit, but then again probably no one would answer the door! Not any one's idea of customer service I'm pretty sure. I'm also patiently awaiting the telephone call from Fabiana in Italy (I also filed a customer service complaint via the Ducati web site) since at least she had the chutzpah to telephone me, even if her call was a complete waste of my time. I am going to telephone DNA every hour and leave a message with the hope that they eventually get tired enough of my calls to call me just so I'll stop. Squeaky wheel gets the grease so they say.

It's nice out today so I think I'll take a break and ride my 87 Honda VFR400R before heading off to meet a client at Court this evening. Hmmmmm, 30 year old brake rotors and no warping there. How on earth can that be possible???????

FURTHER UPDATE: I am sharing the email communication thread with DNA Customer Service since we have reached that stage. I'll be waiting to see what next arrives from DNA. Interesting to note that they make no mention of the telephone conversation lasting over 11 minutes that I had with them. The email received would appear to be the first reply to a customer service contact! No?

Dear Mr. Nicotera,

Thank you for contacting Ducati in regards to your brake concerns. Though we do not approve or deny warranty claims here in Customer Service, nor do we provide technical support, we would like to gather more information regarding your case. When an item such brake rotors are not covered under warranty it is reviewed on a case by case basis.
If you could attach your repair order with the dealer notes it would be helpful in escalating your request.

Best Regard,
Ryan

Ducati North America

Dear Mr. Thompson,


Attached is the repair order copy received by me on April 16, 2016 after traveling 125 miles to reach my Ducati dealer (and a concomitant 125 mile trip home afterward). They verified the inappropriate run out of the rotor and indicated to me that they were recommending replacement. I was also informed that there are NO Ducati supplied specs for run out on Scrambler rotors, contrary to your statement to me on April 21, 2016 that there exists a 5 thousandths spec for run out on the Scrambler. (A ludicrous assertion as such a run out would cause extreme pulsing in the motorcycle front braking system.)


This warping condition became quite noticeable at approximately 2,750 miles and in less than 6 months time since the Scrambler was purchased as a new vehicle on April 30, 2015.



As I indicated in our telephone conversation of April 21, 2016 this is not an isolated incident but rather Scrambler owners world wide are experiencing the same defect. This can be verified by a review of the many postings contained in the several Scrambler forums across the internet, some of which indicate that Ducati is replacing these warped rotor under a warranty for owners in the UK. I expect that Ducati would treat owners here in the USA no less well than those located in the UK and other parts of the world.

Accordingly I expect a replacement rotor from Ducati at the earliest possible date.


Your prompt reply is expected.
