Does your 1290SA clunk when topping out or crossing speed bumps? Check all that apply.

    Supposed to have been new internals since 2016 and this isn't even the same bike as the SA

    Yes but the 2016/2017 bikes have the same suspension (SAS & SAT) and virtually the same as the 2015 bikes apart from a right cartridge with maybe more oil but exactly the same mechanicals.

    My point is there just shouldn't be any way an original 2015 SA part could find its way into a 2017 bike. They aren't the same part number. Basically if it was an old original part it was deliberate.

    Well, clunk is still there and KTM officialy doesn't recognize it anymore as a problem (even though it did 3 times before).

    Here is the email that they send me:

    "We are happy to see that our customers are using their KTM Adventure motorcycles for the scope they are designed for, like you do.
    The issue you are experiencing with your motorcycle is not really a Problem. As we have discussed with KTM R&D mechanics, the "clicking Feeling" of the front Suspension in low Speed small size bumps is completely normal.
    This occures after the first few kms, as the front fork is addapting to the everyday use. Internal parts of the fork have a very small amount of Play that lets the Suspension work as it should.
    So, we consider this effect 100% normal.
    As Mr ------- already explained to you, this is not a Problem, but part of the Standard function of the fork.
    There is no way that this hase any effect in the safety of your motorcycle."

    My new 1290SAS has done this since my first ride and luckly I know of this from YEARS of threads on it here at Advrider... like the shuddering front brakes that will happen soon enough as they still using the same rotors as my 2013 1190 and ok/Nok airbox, same airbox as my 2013 1190 bar one change....yet I still bought the SAS and loving it.

    Rottie intake in already, Scott damper on it's way to sort the now poor excuse for a damper being used...think from 2013 they would upscale the damper at least...and thinking of wave rotors to replace stock......KTM makes biking fun,expensive if you want it to be but fun...must note thou, since 2013 not one of these has caused me to have a breakdown or stranded me...and the old girl is still going strong.

    I have more fun on these bikes than my 1299S race bike or any other race/road bike I have owned in 28yrs....don't get hung up on this old issue, ignore it...fix it or sell the bike and get another to enjoy the ride.

    Life is to short to....imho

    Finally, i find out the clicking sound from the suspension that was normal for KTM (even they didn't know from where it was coming).

    SLIDING BUSHINGS!

    Add some good quality grease to the inside of the upper sliding bushing, and done.

    I've done about 2000km with no clicking sounds.

    Wow, great detective work Whiteyez.

    <sarcasm_section>
    Isn't it great to be an unpaid quality and functionality tester for a huge worldwide multi-million dollar vehicle manufacturing company? The satisfaction we get for wasting our time and money solving the problems they create is reward enough!
    </sarcasm_section>

    Any idea why that bearing is "sliding" in the first place? Does it actually need to be sliding or can it be fixed tight and still perform it's intended job?

    Unfortunately, you are right! Most of us we are testers!

    You misunderstood these metal rings called "sliding bushings", i don't know if this little play that they have is normal or a design flaw of the fork (i don't think that is the sliding bushings cause i changed them with a new set.)

    I wonder if you guys might be confusing two separate issues for the same thing.

    The original "clunk" was in 2015 (and I believe some 2016) 1290SAT's in which the damping cartridge was topping out over smaller bumps, and caused an EXTREMELY noticeable clunking through the bars at low speeds. The original damping cartridges were not "shimmed" enough on the top, so they were replaced by a newer revision of the damping cartridge.

    I had this work done on my 2015 1290SAT and the replacement cartridge completely fixed my clunk.
