    I bought it from a local shop here, I had to fill a form out with all the normal stuff (weight, load, riding style etc)
    add that I wanted the Remote preload adjuster and the adjustable hi/lo speed compression damping adjustment. I figured I was spending alot of money so I may as well get all the bells and whistles.

    The way I understand it to work with the US distributor is they do not keep "stock" units, but assemble them too order. It's kind of nice not having to learn all the details about suspension design to get something that works well.

    Don't follow all the instructions in the Haynes manual, they have people stripping all of the plastic and muffler, but not loosening the chain.

    Tell me about it! There seem to be endless variations from which to choose! I agree about the 'bells and whistles' approach; I'll have a chat with my local BMW dealer. Thanks for the info.

    So, was running Hyperpro springs front and back and I recently upgraded the rear shock to a Wilbers with the piggy back including rebound and compression adjustment. I left the front springs in and have the rear shock dialed in and the bike handles amazing, no matter what I'm riding over I just pick a line and the bike just goes where I want it very smotthly. I have a set of X-Challenge cartridges that will give me rebound and compression adjustments so I can add them and get a little more fine tuned but still really can't add preload. So my question is, considering the huge improvement the rear shock has been and how much nicer the bike handles all around, should I a)leave it alone, b) drop in the Xchallenge cartridges and play around until I get it dialed, or c) just jump in and get the Traxxion setup ?

    Most of my of road riding is jeep trails with gravel to rutted out trails littered with baby heads plus the once every couple of week trek to the Pine Barrens to do a mix of the above with some nice deep sugar sand thrown in:norton


    My other option is drop in the x-challenge cartridges when I do a fork service next month then wait for the new Ohlins set up

    How are the Wilbers working offroad? I still hesitate between them and the Touratech Lv. 2 ones.

    My experience was going from the stock suspension to the AK-20 and then the Wilburs shock.

    I thought the forks were a MUCH bigger improvement than the shock. YMMV

    the FS Roads here are mostly hard pack to loose gravel, there isn't much sand in East TN.

    As far as Traxxion vs Ohlins, for me it came down to $$$$$$$, the Ohlins are so much more I can't see it. (that's the Ohlins USA setup)

    Are the Xchallenge cartidges a drop in?
    I thought Traxxion was very easy to deal with (and for me not that far away)

    That is where it worked best, really planted and plush at the same time plus soaked up everything I threw at it with out ever bottoming out . I wanted the Touratech Extreme but when I inquired I never received a reply, noW it's on their website as available of course but so far pretty happy with the Wilber's. I had an extensive conversation with Ted at the Beemer shop on what I needed it for and can say he had it setup really well for me:D

    Thanks for your reply! Now I'll have to set up my mind about those Wilber's Progressive springs up front. I wanted to go Hyperpro. And back it is to the pro and con list :lol3

    The XChallenge cartridges are a drop in, the springs between both bikes is the same part # which is puzzling and explains some of the complaints of the springs being to soft since there is such a weight difference between both bikes. I haven't had both fork internals side by side yet to determine where the Xchallenge gets the extra 40mm of travel from so I'll update when I do since I've heard conflicting stories as to why.

    Pulled the trigger on the Traxxion AK20's.
    After reading all reports I can't wait for them to arrive.
    I already have a hyperpro rear shock with the lot and all that has done is show me I need to tweak the front end.
    Fingers crossed I like the Traxxions.

    imo you cannot go wrong with the Traxxion front end...better handling on and off road and makes you feel like you're more in control.

    I've been running them for a couple of years on my stunt GS with zero issues...and I think it's a safe bet to say that they take more abuse in that setting than anything you can throw at 'em.

    On the shock front, I couldn't afford the expensive setup, and went with the basic Ohlins shock...what a difference!

    moral of the story which most of us know...bike needs suspension and it is night and day when you set it up

    Just a cool idea.

    a few weeks ago I made the trip to Death Valley, the Racetrack road was about 30 miles each way of non-stop BIG washboard, anything under 60mph was uncomfortable.

    At the end of that, my front end was fine, no issues at all, but the rear shock got hot as a frying pan and started to fade, bottomed out a few times etc, I was looking for big hits, and bumps to really work the suspension.

    It would be an interesting side by side with the various setup to see how they all worked together.

    Oh yeah, I finally put some dings in the stock front rim on that trip, and it's still not bad enough to warrant a replacement Woody's setup yet. Trust me, I'm looking for an excuse to go to a narrower front hoop ;)

    The Hardcore Traxxion Offroad setup arrived today.
    I requested the setting as per Indys recommendations
    5w oil 100mm from top etc etc.
    Unfortunately they sent me 7.5w fork oil and told me to run at 115mm.
    Will it be OK if I just buy some more 5w oil and fill to 100mm from top?

    Cheers

    It should be OK. I guess have a play with different weights heights etc.

    After I did the conversion I thought the 7 turns in on the preload was too much so I backed off to 3 turns. Guess what, I am at 6 turns and think I might go more.

    You will notice a huge difference the first time you ride it. My first impression was that it felt more like my WR.

    Interested in how you go.

    Picked up my Forks from my local suspension shop today and they had some concerns with the whole setup.
    They had to machine a new spacer for under the adjustable cap as the unit supplied was just too sloppy. Also they said the rebound strut felt more like compression and visa versa? :huh
    They just installed as parts were marked and I will see how it performs this weekend.
    Can wait! Hope it is as good as everybody says. :clap

    Well tested the Traxxions on the weekend and they are a huge improvement.
    They will only get better once I fiddle with the settings.
    Really happy with the AK20's up front and the hyperpro with the lot in the rear.
    Dialing them in on the other hand perfectly for me is going to take a little time .
    Already it is a huge improvement !

    Bottomed mine out on sunday. Think I need a bit more preload ( or slow down! )

    raise the oil level to 100 mm from the top of the collapsed fork with spring and dampener rod installed to help improve bottoming resistance.:D

    Think I am at 100mm. I can't remember what oil I have in it. It was a hard hit on a very square edge! after topping out.

    occasional bottoming is perfectly fine. try turning up your compression dampening a turn or two.
