    this was some really crude info i had found a while back and tried to make sense of to see how far you could stretch the shock using parts bin stuff. It's all based part fiche searches.

    Theory - hybrid shock out of 2003 525 EXC shock parts and 9x0 adv shock parts should turn shock into a +/- 300 or 320mm travel rear end, but i don't have any parts to try to verify.

    Stock 9x0: part # 50180237 RESERVOIR SCREW L=123,5 D=52
    Xtra Stretch: part # 50180351 RESERVOIR SCREW L=140 D=52

    Stock 9x0: part # 50180362 PISTON ROD D=18 M16X1
    xtra stretch: part# 50180294 Spindel D=18, L=153, M16x1 (aka piston rod)

    stock 9x0: part # 50180364 NEEDLE L=161
    xtra stretch: part# 50180261 Needle L=175

    stock 9x0: part # 50180367 TUBE M54X1 L=180 PDS
    xtra stretch: part# 50180295 Tube Pds L=196

    you can use https://www.motosport.com/oem-parts/part-number/50180261 to cross reference models by part numbers to help scout ebay for parts.

    The parts listed above may work, but no one that i know has verified if thread pitch on any of this stuff is the same. The list has parts that would need to be longer to account for greater movement, the diameters of stuff seems to align with the stock ADV diameters, so things like valve pistons should be reusable. But like alongat mentioned you may have to remove the ADV eyelet from the stock shaft and reattach it to the longer early 525exc/300exc shaft after removing the clevis. Only way is to start a parts horde and see what matches. I suspect WP is a parts bin company and things should swap pretty easy.

    any idea what length is a stock ADV shock shaft?

    I have a SKF seal head that is meant for late RFS EXC now, same dimensions as stock. Im actually more than happy with the stock height and PDS, It needs some more damping in the bottoming piston but I'll look into it in the next service. Just technical curiosity with the extension.

    Well...I can tell you that using the 123 or 140mm reservoir are non-starters for a bolt on solution for the SE. Does anyone feel that these are required? Technically speaking, it makes sense for a larger reservoir with more shock stroke but how to calculate the minimum requirement? Ktm used the 123mm reservoir on the Adv shock for 6 years before moving to the 95mm short reservoir with the same travel / shock lengths.

    I’ve been very curious about whether the Adv Wilber’s has the reservoir in a location that would work on the SE. This is great to know as I’ve heard very good things about the shock and Wilber’s quality and post sale service.

    This post and your posts on the SE shock have been very helpful, you should put it in the links thread at the top of the forum. I'll do it for you if you want.



    I did the same with the OEM shock, it still sucks. The bike pogo sticks like a mf in the rough at speed. The only time this shock has been accommodating is when I have the bike fully loaded for rtw trip. When it's just me it's a wild ride.

    there is a separate manual. i know i have the fork section i will look through my files to see if i have the shock section, i don't recall anything specific to ADVs just the little bikes. But they are all basically the same.


    Here is a generic wp shock manual

    Cheers Rharr,

    I'm pretty cool with the shock just the preload adjuster. I'm going to strip and service myself, was hoping a manual would have part numbers so any bits I will need are easy to order.

    I'm excited about getting this done, I was told way back in 2007 that the Adv Shock would NOT fit....

    use this
    https://sparepartsfinder.ktm.com/

    https://sparepartsfinder.ktm.com/Co...635?modelidentifier=1000177211&isEngine=False

    and look under 2006 and earlier models for individual part numbers.

    preload rebuild
    https://advrider.com/f/threads/hydraulic-preload-rebuild-whos-done-it.1100503/

    tip, order a few extra o-rings in case one tears, or better yet, order enough parts to rebuild it twice, as i am not sure how long they will be on the market since not many ktms use this hydraulic preloader.

    By the way, this is one I found with Google. The ones that were raced against HP2's. Basically a 950 SM with some farkles and Adv swing. The spring looks like 950 PDS shock spring, so it is a 50mm Shock, it has to be PDS because they wanted to win. The rest is a question does anybody recognize?

    Anyone clarify the difference between 50180114 Intermediate washer spring 61 and 50180402 INTERM.RING SPRING RET. H=3,5?

    The two off the 2006 shock with 225 spring look identical and are both 3.5mm.

    What did that cost you? I like the idea of a bolt on solution. I think the powercell olins is about 2 thousand. eeek

    I contacted Wilbers about the Adventure shock for the SE after seeing johnno950 had one.
    As soon as you tell them you want it for a SE they get all TUV on you.
