    Look what I just scored for 160 euro.

    The spring is 140-255 and the reservoir is 128mm long.

    Just making sure that I want these things:
    • KTM 50180522 this should be the shorter reservoir
    • KTM 50180161 shim in order to install 265 spring
    Where do you guys suggest to buy the 140-265 spring?

    What? Yours is easy:
    1- no need to change the internal shim as yours is the thin one
    2- I like WP springs from KTM
    3- you need the L100 length reservoir

    +1 - just do a total service and be done with it.

    @Rharr @alongat the shock is getting full rebuild...

    I usually get full rebuild on all the suspension on my EXC twice the year and one a year on SE...

    Hey syky27,

    I just got a hold of this same shock. Mine is off a 2004 950 ADV. Same spring 140/255. Would you be up for a few questions about your set up?

    Best Regards/Troy

    Did you end up needing to use the thin shim/spacer p/n 50180161 and spring 140/265 to mod the shock to get correct length for the SE?

    Yes mate - Same info I sent you via messages.

    For anyone else reading this:

    Ktm 950adv shock into an SE:
    1 - you need the short reservoir from an SX85
    2- you need the thin internal shim
    3- you need either the 255 or 265mm length S / R (or other) spring
    4- you remove the black external spring spacer being used on the current 225mm spring

    Ktm 950advS shock into an SE:
    1- you need the short reservoir from the SX85

    Ktm 990adv shock (early years 2007-2009/10)
    Same as 950adv above

    Ktm 990advR (or 2006 990advS in EU)
    1- you need the short reservoir from the SX85

    Ktm 990advR (2010 and up - has a reservoir with five grooves not seven)
    1- needs nothing, bolts right on

    In all cases, there is a small portion of the very front corner of the underseat battery box that protrudes a tiny bit at the very front where there is a plastic lip. This interferes with the Adv shock preload adjuster and makes it feel like the adjuster cannot be tucked in. Simply trim a bit of that plastic lip to get rid of this interference. Also, you should note that most people have experienced an increase in ride height by between 10mm-14mm over the stock SE shock. This is hardly noticeable unless you’re already struggling to reach. Message me if this is a concern and I can also explain how to mitigate this with a different spring and internal shim.

    In terms of spring rates, the SE comes with a 140 rate spring and many people switch to a 130. At 102kg plus riding kit, I’ve been using the 130/265 on my Adv shock in my SE and have found it a tad soft since I don’t like to add preload to correct rate...the 140 appears to be much more suitable for me. I don’t take passengers and when loaded with luggage, the Adv shock offers an additional 16mm of preload via the adjuster to compensate for the luggage weight.

    Excellent post, this needs to be saved in the H.O.W. for future reference. Thanks Alon for taking the time to share.

    Thanks man. I didn’t start the thread otherwise I’d edit the first post so that it includes all the information on the variations of shocks, combinations of resulting travel/seat heights, part numbers and even some valving that I think we could all benefit from.

    Just like @alongat says

    Shim: 50180161
    Reservoir: 50180522
    Spring is up to you...

    You can always reuse the original Reservoir if you shorten it. I picked the easy way of buying new shit...

    The PDS shock is deffinately superior compared to the stock, more traction, much better bottoming resistance with the stock Adv valving. It really makes the bike feel like big EXC instead of a front-heavy adventure bike.
    It does bottom out to the rear fender when pushed properly. 100kg driver, 140N/mm spring and Michelin AC10 tyre, enduro, no big jumps. The paradox is that with the stock shock I couldn't go fast enough to make the PDS bottom out. It is ok for the summer, for the spike season this is going to be dangerous so I need to figure out some valving for the bottom piston and make some space between the fender and the tyre. Either modify the fender or make a spacer for the shock.

    Any updates, I sourced 2006 shock so need to order bits, size of spring is my uncertainty. I believe I'm around 102Kg but I'll be having a passenger from time to time.

    Zero issues - no regrets. I’d say the 140 rate is correct for your weight (I’m the same weight) and you can always crank up the preload for the classic album passenger.

    You’ll need the short reservoir for the 2006 shock...

    I did initially but have been running a 140 - you know how it goes...I’m going to lose weight...blah, blah, blah... :)
