    For those of you riding a 790ADV R, did your shock fail yet or not? If yes, can you indicate which month the bike was delivered in? Maybe we can see a pattern of production dates and failures.

    Is the production date/month encoded in the VIN? Maybe thats a tighter means to track a defective batch @kubcat

    I was wondering that myself. Googling around, it seems that all we can get is model year and S/N. Once we get a significant number of replies, maybe we can ask them to post S/Ns, or maybe someone knows the alignment of S/Ns to production dates.

    Same conclusion found here, by googling. Only yr produced, and then serial # after that. Maybe 2 or 3 guys with failures could compare serial #'s and see if they're close or not. But it would be nice if we knew something about the serial #'s and could broaden the failure criteria to a certain range of #'s and then systematically hone in on a bad range.

    I can add this - I'm well over the 2000 mile mark that some seem to fail at and my serial is between 750000 and 800000.

    Not to stir the pot here but trying to find shock failure trends by the motorcycle production dates may not reveal much. Delivery dates to the end user even less. If anything, the goal is to narrow down the shock production series and try and identify a trend that way.

    It’s not like shock serial number 1 went into ktm 790r number 1. WP (as other suppliers in automotive/motorcycle manufacturing) deliver their components by the boot load. So, unless the KTM production line has a FIFO system, this may be hard to trend. In reality it may be more of a LIFO system. Do they maintain a serialized bill of materials system that ties to the VIN?

    Bikes then get shipped around the world. Or are they organizing their production line and saying “ok the next 50 bikes are going to Australia, then the next 50 to Argentina, and so on”?

    The expectation is that the engineering groups in KTM and WP are talking, researching, testing, and implement engineering changes into production at defined moments.

    I’m not a 790 owner but reading this entire 790/890 section with a lot of interest. I hope this shock issue is figured out. Let’s see what those with 2020’s report once they’ve ridden them for a while. We all want to see this bike succeeed. Actually, it’s already a success.

    This all reminds me of Fight Club...

    JACK (V.O.)
    Take the number of vehicles in the
    field, (A), and multiply it by the
    probable rate of failure, (B), then
    multiply the result by the average
    out-of-court settlement, (C). A
    times B times C equals X...

    Jack is speaking to the BUSINESSWOMAN next to him.

    JACK
    If X is less than the cost of a
    recall, we don't do one.

    BUSINESS WOMAN
    Are there a lot of these kinds of
    accidents?

    JACK
    Oh, you wouldn't believe.

    They definitely track the BOMs against the VIN, specifically the serialized components like shocks, frames, and engines. Other parts they will track by lots against the serial groups produced while those lots are in WIP. Without that tracking mechanism, the liability exposure cannot realistically be contained for catastrophic damage (loss of life due to manufacturer negligence).

    You are right that we would ideally track the VINs against the shock lots, or better yet, against the specific serial numbers of the shocks. You know that's what KTM is doing, but we have no access to that data, so the goal here would be to see if the faulty shocks all came from the same lot(s) by approximating the production runs as best we can know - by delivery date. We may not have enough inmate owners to get a valid data sample. But given enough data, the logic is sound and a pattern will emerge,

    My bike is in that range too and just went over 2,000 miles today and shock is still OK.

    Interesting points on your first paragraph. Makes sense.

    Do the shocks themselves have a unique serial number marking somewhere? Asking for friend... @Torque @AdvRonski

    I will check a shock tomorrow. The fork lugs generally have date of manufacture but have not seen that on a shock to my recollection.

    Our bikes are less than 3 dozen apart. Too funny :)

    YOU are doomed my Man! :)

    So, the folks that have had shock failures... might you post up your VIN SNo for collation?

    Surely with such data, a cell would be evident if it's a WP manufacturing glitch.
    Unless Murphy made a factory tour... Or several?

    Between mine and @Aceyduce 's SNo's there's 9860 units.... Multiply that by the MSRP.

    :eek2

    I also posted a similar survey on FB in the 790 Adventure Owners & Fans Group, at this link https://www.facebook.com/groups/1052137711659992/permalink/1226661377540957/
    It looks to be a significantly larger sample size than what we have here. You may have to join the group to see the posts. Anyway, here is a screen shot of the current poll results. Interesting to note that the reported failures only make up 11.6% of voters, while those of us not affected (yet) make up 88.4%, with a total of 69 votes in. looks like it may not be as widespread as this forum may have led me (us all) to believe, unless all the others that have had failures already got them fixed, are out riding, and still haven't seen these polls:muutt

    Almost 7,000 miles on my R, no leaks or indications of an issue with the rear shock. Suspect this is a much smaller problem than it seems like on the surface, though a 10% failure rate is definetely still a serious problem... just not as serious as 50%
