Fuel leak at pump/tank interface
After opening this PE, we met with subject owners, dealers, and Ducati North America personnel.We learned that the subject leakage is limited to the Multistrada line alone and is unrelated to composite fuel tank deformation.Rather it stems from the inability of the original sealing O-ring to conform to the tank's relatively rough sealing surface.Recall 11V‑020 provides a new X section O-ring to address the Multistrada issue and with that recall, this PE is closed for the Multistrada.Meanwhile, unlike the Multistrada, the Monster line fails to exhibit a current safety defect trend and, on that basis, this PE is closed for those models as well.

What 2006 Ducati Monster S4 R owners say
Most recent owner complaints, unedited.
My motorcycle has a plastic gas tank which has begun to expand. The outside dimensions of the tank have increased and it now does not sit correctly in the frame, the handlebars hit it on turning, and it presses against the ignition switch. Previously it opened and closed without problems, now I have to wedge it against the ignition switch to close it. The rubber mounts no longer sit on the frame. I have not significantly modified my motorcycle except for an aftermarket exhaust and some cosmetic changes. I have made no modifications to the fuel tank or fuel pump. I took the bike to the dealer (hattar motorsports) who submitted a claim to ducati north america (the importer/factory). I have been told it will be replaced. I am very concerned as to the safety of this motorcycle now. The tank's swelling has made it so the handlebars do not turn correctly. If the tank swells enough, it will split open and I am concerned this will happen while I am riding.
Plastic fuel tank swelling.
I own a 2006 ducati monster s2r-1000 (purchased new 11/2006), and it has a plastic gas tank that has become distorted from its original shape. My fuel tank has become distorted on the left/ right sides of the tank in the area where my knees touch the tank. There is some type of demformation around the gas cap, which is causing the paint to crack. The rubber pucks, which are on the bottom of the tank, support the tank on the frame. The pucks no longer sit correctly on the frame, and the tank does not sit securely on the frame.
I have a 2006 ducati monster s2r1000 with approximately 2500 miles on it. My motorcycle has a plastic gas tank which has begun to expand. The outside dimensions of the tank have increased and it now does not sit correctly in the frame, the handlebars hit it on turning, and it presses against the ignition switch. Previously it opened and closed without problems, now I have to wedge it against the ignition switch to close it. The rubber mounts no longer sit on the frame. I have made no modifications to the fuel tank or fuel pump. The bike is completely stock. I am very concerned as to the safety of this motorcycle now. The tank's swelling has made it so the handlebars do not turn correctly. If the tank swells enough, it will split open and I am concerned this will happen while I am riding. As well I fear this may be a fire hazard as gas could spill out while riding. I asked the local ducati dealer about the problem and they informed me that the only way that they could replace or look at is if has already started to leak fuel, which mine has not yet.
Plastic gas tank expanding on ducati monster s2r1000. Tank has not ruptured or failed yet, but continued expansion could cause damage.
The plastic gas tank on my motorcycle is swelling, causing it to not fit properly on the frame anymore. It is also interfering with the ignition switch and tank latch mechanism. There is also cosmetic damage (ripples) on the side of the tank. Am worried that tank will eventually fail or leak.
The gas tank on my 2006 ducati monster s2r has expanded in both width and length. The larger dimensions now allow the handlebars to hit the tank which could cause a loss of control/crash. Another worrisome issue with an ever-expanding plastic gas tank is the fact that it sits in your lap while riding. Not really where I would want a sudden expulsion of flammable liquid onto a hot engine when the tank splits open.
My motorcycle has a plastic gas tank which has begun to expand. The outside dimensions of the tank have increased and it now does not sit correctly in the frame, the handlebars nearly hit it on turning, and it nearly presses against the ignition switch. The rubber mounts no longer sit on the frame - they each sit out 1/4 to 1/2". I have not significantly modified my motorcycle except for an aftermarket exhaust and some cosmetic changes. I have made no modifications to the fuel tank or fuel pump. I took the bike to the dealer who adjusted the tank and thought it was simply out of adjustment. I am very concerned as to the safety of this motorcycle now. The tank's swelling has made it so the handlebars do not turn correctly. If the tank swells enough, it will split open and I am concerned this will happen while I am riding.
Recently found that my fuel tank on my 2006 ducati monster s2r 800 motorcycle has expanded and is becoming deformed causing contact between latch and ignition switch. Also found that the tank no longer properly rests on the frame.
