    I have ordered Wilbers for the rear suspension of my X bike. I really liked them on an 1150 GS Adventure I had. More than just the fear of an air shock failure, I'm replacing it for rally racing...hoping for improved performance. I'll let everybody know how it works out in a few weeks.

    I'll have a slightly used stock air shock available soon. ;~)

    Undetermined. It was annoying, but the greater concern of the dealer was that something was not working right inside the shock. Performance was fine but reliability was unknown. I didn't make the call on even fixing it. I just wanted it noted. A Puma case later and BMW was sending new parts, so it may have been serious. If that thing blows out the bike is dead in the water, which I would not have thought about without this ordeal.

    Had a fun time yesterday riding my X-Challenge at an OHRV park close to home. Photos on SmugMug.

    It was very easy to remove the air suspension and install the Wilbers. I was done in about a half hour.

    The bike's handling is much improved. The other guys on the ride were on bikes in the 220-450 CC range. I didn't have much trouble keeping up when it got tricky. The terrain was muddy with many roots. Some very rocky sections and steep climbs. The bike seemed planted and always gave good traction. I did bottom out the suspension twice when jumping off water bars. Not sure if I should increase the preload or something? The suspension was built for my weight and 100% off-road setup. I haven't really changed any settings.

    Overall, I'm very pleased with the Wilbers. :clap After this ride, I've decided I will enter a turkey run next weekend. :gdog

    FreeThe Beast; -Did the bike got higher than stock with the Wilbers ?


    I heard the Öhlins got much higher and that's not good for my 5'8"...:wink:

    I ordered the Wilbers at the standard height. I haven't put a yardstick to it, but it feels the same. I guess you can order the Wilbers at different heights. I didn't have a need to change it.

    Has anyone considered the rear shock off the X moto or motard, whatever they call it? Same frame so it should bolt right in.

    Both are shorter shocks than the shock for the X challenge.

    I added the washers and did the heat and bend as well of the plastic flap. Needs a double bend otherwise too close to tyre Anyway, we shall see.

    I am wondering though if all we should do is remove the plastic flap and install something a little bit more like the shock flap you see on enduros, on the outside of the undertray rather than the current position

    Ok I know we shouldnt have to but look, I am an ex-GS owner :augie :lol3

    I ordered it through MAX BMW. Rose can help you with it.

    I believe you can get taller or shorter height, but I didn't make any changes.

    Oh, by the way, I don't need the air shock anymore. I'd be happy to part with it for a fair AdvRider price. It has about 1,000 miles on it.

    Wow, people still struggling with the mud flap. I dont have any pics but here is how I fixed mine and its perfect. I didnt like the washer bit.
    I did mine in the summer, so take note on what the cold would/could do.
    It was a warm summer night, 60ish. I bent the mud flap back against the tire so the bottom of the flap was pointed up, with a big bend in the middle. I left it over night. In the morning I forced it back. It rubbed against the tire so I took a hair dryer (wife's) warmed it up a bit and walla'! Its never rubbed on the bag.:clap

    Ive read a few posts on replacement shocks, some seem to be pretty satisfied. I have learned that the bag is really pretty good. I fiddled with it for awhile and set it up for what kind of riding Im doing. Sometimes improvements were counter to my intuition (try higher bag pressure with 'soft' damping). Now Im 265lbs and what works for me may not for you but I like the adjustability to the load, I carry abit and Its never let me down and I dont believe it will. I like it.

    Installed a Ohlins X moto shock on my Xchal. It lowered it enough so I can now touch both feet at standstill. I found the shock on Ohlins USA website under inventofy close out for $495.00 +shipping. I have not been able to ride yet but will give report afterwards.

    Just installed the shock, not much to it.:clap :clap

    1. put bike on a stand - to raise rear wheel
    2. remove rear wheel
    3. remove the silencer
    4. undo the bolt & nut at base of shock
    5. undo bolt on top of shock
    6. remove shock
    7. repeat process in reverse to install new shock
