    Also, suggest you to replace the seals from the newer 2017 Duke 390 which are much improved and is sourced from a different vendor.
    Yes there are minor scratches on the lower part of tube which is open and visible part of tube. These scratches visible only when checked carefully.
    I was in Mumbai and bike was kept without cleaning after driving in rain. So there is little rusting at end
    Lower part of tube.
    As per SVC They have same oil seals for all models nothing different for 2017 model.

      sometimes improper installation of the seals can also cause premature failure.

      usually just the fork stanchion tubes can be replaced. how much did they quote for the tube ? the entire set is pretty expensive.
      Yes they are quoting 3-4k for tube and 9-10k for entire fork including labour.

        Seals going bust repeatedly isn't something common. IIRC, one fork leg costs close to 8.5k-ish and both 200 and 390 have the same leg. If you can source a fork set from the used parts market, you could save some. Dust, and scoring or fine pitting on the fork slider would mean seals going bust often. It's very hard to diagnose without seeing the slider and examining it carefully. Any idea the amount of oil they poured in? 450 ML is the right ballpark, too much and the seals would go bust soon.

        Cheers!

        Yes VJ. I was there when it was replaced and I purposefully asked him to not over fill the tubes. Yes some oil was left in the bottle.

          Scratches whatseover shouldn't be present in a fork slider, and given that we have rusting which is basically pitting would rub against the seal and cause a seal failure. Some fork menders even polish the fork sliders to make sure they are clean all round. What I'd suggest is get the tubes alone and get them replaced. Also I'd recommend you to ask the SVC personnel themselves if they can suggest a place where they can polish the fork sliders, doing so will eliminate all possible hotspots on the tube and allow for a smoother tube travel which ruining the seals. Can you post a picture of your fork slider (the chrome part) so that we can see where the rusting is.

          Cheers!

          Once upon a time, a guy asked a girl 'Will you marry me?'
          The girl said, 'NO!'


          And the guy lived happily ever after and rode motorcycles and watched sport on a big screen TV, went fishing and surfing, and played golf a lot, and drank beer and scotch and had tons of money in the bank and left the toilet seat up and farted whenever he wanted.

              From what I can see, your slider definitely needs polishing. Coupled with the dust accumulated along with the fork oil, these act like sandpaper during each stroke of the fork and ruin the seals. Apart from this I can see minute rust spotting on the fork which isn't good, it's these that compromise the oil seal's sealing ability. I'd suggest you two options, replace the fork sliders procuring it from a used market or if there is a possibility of polishing the slider I'd suggest you that. I for one, would definitely recommend replacement of the fork sliders or the entire kit itself as a last resort.

              Cheers!

                  just the tube should be enough. and don't pick up used/scrap parts, it could end up money down the drain.
                  3-4k is ok imo & you get a peace of mind knowing it's a new part without any defects.

                    Guys can a reliable local mechanic can handle KTMs ?

                    I hope some extra sensors are present in KTM bikes .
                    what's the major differences between KTMs and others??

                        yes and no.
                        for most of the regular services, it is as simple as most other bikes. one just needs to know where the parts are located and how to open up stuff and put it back together. the workshop manual is available which you can refer to.
                        also just observe the service being done at the svc, and you can then sit with your local mechanic and get general servicing done.

                        Meanwhile in some cases, the diagnostic tool is required.. especially for diagnosing electronics related stuff like the FI system, sensors etc.. if you see the check engine light come on.

                        Can be.. but tricky, gotta fight with the svc.
                        i've had fork seals replaced under warranty.. had to just pay for the fork oil.

                          Yes, they can. It takes a little know-how and ruining a few Dukes in the process
                          KTMs aren't way different from any motorcycles out there. Sensors yes, you have a couple of sensors more than a normal motorcycle and of course the engine is a different setup altogether, but nothing significantly confusing to a discerned mechanic. As motorcycles get complicated, so does the diagnoses part of it which requires OBD readers and what not. Anyone who is adept at repairing an NS/RS 200 engine would easily be able to handle a KTM engine, for the most part, no big deal. But you cannot trust every nook and cranny mechanic, that's the catch.

                              A simple google search will throw you the results.. the ktm ones are easily available. I've also posted it here on xbhp earlier.
                              which one do you need ?

                                Actually I'm a P220 owner. So it's a bit hard to come by, I found the one for P220 but mine is 2018 BS4. If you find it somewhere, I'd be thankful.
