    Whatever success you have up front may be negated by the Ohlins in the rear. Sad, but true.
    Better than stock, but not a great solution for the price.

    Not at all. The other aftermarket (and stock) shocks will produce the same results if not dealt with properly.
    For the money, there are much better shocks out there when the overall ride and adjustability are factored in.
    At least they (Ohlins) look cool.

    They will work on anything. They are in business to make $$$ like the rest of us.

    What did you end up with Johngill? Hyperpro or other?

    Think I got my problems sorted out with the Traxxion. Long story short, using 5wt oil and setting the level at 95mm from the top fixed it. The adjuster range is working well now for both C & R, and the fork only bottoms out (lightly) on the hardest of landings......which is what I want. Fork action feels great everywhere, in all scenarios.

    My final oil height is higher than most recommended settings (which are 110 - 115mm range). The Traxxion tech (Dan) confirmed not to exceed an oil height of 90mm. I got mighty close to that before I was satisfied. Anyway, no more blowing thru the stroke on hard landing. Now, the damping action feels right....very progressive to a stop. There just wasn't any stop before. It would bottom out on the internals. Even 100mm didn't stop it. When I brought the oil level up to 95mm, it was magical.

    Thanks for the input, Indy. Good advice! Its a bit of a PITA to do this correctly. I had to secure the right tools, and make several roundtrips on & off the bike to incrementally figure this out.

    Now, I've got to work on dialing my Ohlins in tighter. Its still bucking me a good bit on rebound at the max setting. So, I'm not there yet...

    Yeah you need to play with the settings, oil level and oil weight to fine tune the Traxxions for your riding style and terrain.
    I have no complaints with their tech support and the beauty of these is once you got them where you like them they just last and last and remain consistent. I just wish BMW had some thing like this stock. I have developed a Traxxion AK-20 set up and an Elka 3 way custom rear shock for my buddies highly modified Versys ( 8" suspension travel on both ends) and I am very impressed with the Elka quality and adjust range!

    Was this a fully customised job? Can't see anything listed for the F800GS on their website. :norton
    Did they say if they are building any more?

    They will build them Just call and ask for the F800GS kit with our ADVrider team developed set up.
    The AK-20 cartridge product is great and will last and last compared to pressurized gas units.

    Here is the latest set up that works great with the Traxxion Dynamics AK-20 Kit:

    Preload spacer length 225 mm
    Oil level 100 mm using 5 wt fork oil

    Springs 0.60 kg/mm x 310
    mm long
    Range of adjusters is 4.5 turns

    Cartridge valves set at C 3 R 3
    New fork caps with preload adjustment and compression adjustor on one fork and rebound adjustment on the other fork cap
    custom tools for install and service

    Spec all that when ordering the kit and get the custom tools for $100 from Dan Anderson at Traxxion Dynamcs.

    Thanks for the info. Good to hear there is a real alternative to the Ohlins NIX or TTX cartridges. :clap

    Being in OZ I won't be sending my forks to the USA, I'll buy the optional fitting kit instead.

    Any idea of price? :ear

    I have done the AK-20 kits myself on other bikes on this forum. Piece of cake to install.
    The first few we had to send in while they developed the fork caps and fit.

    The kits run around $1,050. US plus some custom tools for $100. that are handy.

    Thanks. They got back to me; $1,199 and a couple of days to get a kit ready.
    They have moved on from your specs apparently. And now offer 3 setups; "hard core" off road, ADV tourer and street.

    They should be quite an improvement over OEM, being fully adjustable and rebuildable, etc.
    I wish there was some comparison with the Ohlins kits was available though.
    Its 2/3rds the price, but don't hear much about their plushness or ride quality etc... :ear

    I have just installed my forks with the AK-20 kit

    Currently Traxxion Dynamics offers 3 different setups

    1. street oriented
    2. "adventure touring" 90%street 10% dirt
    3. "hardcore" offroad

    the main differences seem to be spring rate.

    I decided to go with the off road setup. My riding tends to be about 70/30 but the dirt is usually not smooth.

    Because of the amount of time I've been spending at work I removed the forks and sent them to have the kit installed.

    over the phone I was told they are running a 1 1/2 week turnaround, they finished them in 8 days from when they received them, and it took me 2 evenings to install (because my smaller torque wrench was at work).

    Last night I had time for a short ride, only 1/4mi dirt.

    I can tell a huge difference, the brake dive is minimal, the bike feels much more solid in the front without jarring me through the handlebars. I can't wait to get a better ride in.

    Now I can tell the shock sucks too, over minimal bumps the rebound is very fast. I have a wilburs shock on order, I can't wait.

    Most of us spending this kind of money fit into the last category! Hardcore off road freaks!:wink:

    I will never say I'm a Hardcore off road rider, freak is a different story:evil.

    My thought was since I'm not pushing myself to the bikes limits on pavement I want the biggest improvement off pavement.

    the $$$$$ was just to get something I think will fix the problems......without introducing several more.

    It looks like the first good test will be Sunday, I hate when work interferes with fun:cry, but it does make buying toys easier

    After taking a decent ride yesterday all I can say is WOO HOO:clap:clap:clap:clap:D:D:D:D:D:D:D




    Where's my new shock.


    For anyone who knows East TN, From Vonore I took 360 to Citico road, to the Cherohala Skyway, to Hooper bald, to N River road, to Whigg meadows back to N river rd to river road to 360 back to Vonore. its a good mix of good pavement, rough pavement, dirt, gravel, whoops, REALLY loose gravel etc.

    with the stock forks 30mph on Citico road is brutal, very harsh, jaring thinking things are going to shake loose, with the AK-20's I looked down to see if the had graded the potholes out and saw "damn I'm in 4th gear going 45mph, I'd better slow down.:evil:evil

    they soak up all the minor holes /rocks etc, and just roll over the bigger ones, I didn't air the tires down so some of the looser gravel was pretty interesting (marbles) but no surprises from the front end.

    I did stop and turned the rear rebound adjuster about 1/4 turn harder, and that slowed down the eject feeling, the shock is just not working as well as the forks now.

    I should have my Wilburs in 1-2 weeks

    In short, the ak-20 is not cheap, but it is about $600 less than Ohlins USA, it is adjustable and rebuildable, compared to the other options it's your decision, I'm not unhappy with mine.

    The best money ever spent on this bike is suspension!
    I rode the stock suspension for 600 miles and ripped them off and went Traxxion AK-20 and Hyperpro 3 way.
    I got 36,000 miles now and I love to charge pot holed and cratered old back roads with her at 60 mph.
    The aftermarket suspensions make the bike handle very very well!

    Machinebuilder, have you had the Wilber fitted yet? If so, what's the verdict? I'm thinking of getting exactly the same setup on my F800, so I'd be interested in your thoughts.

    I'm not into hardcore off roading, I just want suspension that allows me to go wherever I choose, irrespective of surface. I also want my setup tp cope with my luggage (metal panniers, 38l each side, camping gear on top).

    Yes I got it back in August, I would not hesitate to go with the Wilburs Shock or the AK-20 Fork. :D:D:D

    I did have a minor pogo sticking with the fork, I think I got past it by adjusting both dampers a little. I was going to call Traxxion about it but decided to try small tweaks.

    Do to time and work most of the miles I have put on it are were paved roads, the difference is unreal, even with the "extreme offroad" setup I feel much more confident. Riding on forest service roads and 2 track it really shines, no jarring in the handle bars and I will willingly ride MUCH faster. ( I'm still slow compared to some people).


    I went this direction because I thought for me and where I like to ride, I wanted the most improvement off road, I just didn't realize the difference it would make on road. I am sure the bike will go many more places than I am willing to take it. I really want to go back to Colorado now.

    Excellent news; thanks for that! I, too, would probably go for the off road set up. It's great to hear that there's a noticeable improvement on road, too! :clap

    Just another quick question - what type of Wilber rear shock have you used? A site I'm looking at has many, many possibilities (unless I'm being thick and reading it wrong!).

    Cheers.
