    So with spring somewhat on the horizon, I, probably along with many fellow F8 owners plan on the all too coveted front fork upgrade.... I've done a lot of reading, and was hoping to get a consensus of the pros/cons of each setup out there..... I'm really interested in functionality, longevity, and price. So far I think the following upgrades are available

    Cheapest/easiest- New springs/oil

    Cheapest cartridge set- Bitubo

    Higher end setups- ohlins or traxxion

    Cheaper but more difficult- front end swap

    Anyone with experience please chime in with the pros/cons or any other options. Hoping that an all inclusive thread might help us that are looking to do this soon. Thanks!

    You really can't beat the Traxxion Dynamics AK-20 kit with valving rates developed here by ADV riders.
    The off road valving eliminates the harsh high speed compression jolts that go right thru your arms and kick your hands off the bars of the stock suspension. Adjustable dampening is nice and you just need to pick your spring rates from mid .50s to low .60s depending on rider weight and average additional loads.

    I had my forks worked over by Alex of Konflict Motorsports. Great guy that really knows his stuff. For the 800 he has a custom fully adjustable solution. I have put 40+ thousand KMs on the set up in all types of conditions and they have been fantastic.

    Alex is an excellent resource even if you don't go with his solution. He has also been chosen by Touratech USA as there tech for the new rear shock line. Like I said guy knows his stuff.

    Is this a ship your forks in and they do the work type solution, or order a cartridge set and they send you the kit(similar to ohlins/traxxoin).

    Whats the pricing on a setup for the F800?

    Glad to hear the input from different folks on this

    AK-20 kit is around $1,200 and installs easily at home no need to ship forks anywhere.

    The F800 fork solution is a complete service, all work is done in house (minus the machining). I sublet that out to ex-boeing machinists as they are much better than me on a lathe!

    I do offer shipping cartons (gun cases) to ship your forks in with an appointment.

    Listed below is the link to my ad in the vendor section.

    I have also as of the 1/1/2013 started a 10% discount to ADVrider members that does apply to this service! :deal

    Does anyone already have a 2013 model and can offer some review of the new forks? Weren't they changed to a new make or model forks from ones used on older-year models? If so are same upgrades needed with new forks?

    Thanks,
    Steve

    They are WP. I can say that I have already bottomed mine out offroad (could tell by where dirt was wiped by the seals) and coming from a G650GS I notice way more front end dive when I chop the throttle or brake.

    AK-20 kit will work on 2013 models but the since the forks use smaller tubes owners will need to send their forks in to Traxxion Dynamicx to rework the stock fork caps. They make new fork caps for the 2012 and later models in their online kits.

    You'd figure that with all these suspension threads that a bmw rep. would get a clue.

    Lol you would think. They could have doubled sales if they at least made adjustable forks for 2013.

    +1 for Alex
    I called Alex earlier this week and he gave me a 1/2 tutorial on suspension (or lack thereof on my '10 F8GS). He didn't try to 'sell me' on anything, just gave me information, options and advice for my body type and riding style. I'm local to his shop and I've got an appt to drop my bike off the week of March 11th to swap out the springs in the front end and an upgraded shock on the back. Alex seams to be a nice guy and he know his stuff. I look forward to working with him and to get to finally 'know' what I haven't 'known'.

    Stop that now!

    They'll take you off their Christmas card list.


    I had a Showa fork set off an RMZ 450 that I picked up brand spanking new on eBay for US$400, and I had Emig racing do a set of F800GS custom triples and bore them to suit the Showas, for a cost of $1200 with a steering damper (it leaked oil a lot but I found a dodgy O-ring and changed it - no more leaks).

    I took one brake disc off, made a caliper bracket, and fitted a front master cylinder off a DR650. No....I don't want to hear about the oil magically vaporising and having no brakes. In a very violent 10000kms or so off road it hasn't yet. Brakes work well, you wouldn't know there was a disc missing until you do things like bang into a hairpin with wife and camping gear at 180kph. Then you'll initially notice there's less brake force. I don't know if it's me mashing the lever all the way to the bars or not, but it seems to pull up ok after the initial beige feeling. No, I'm not joking.

    As for functionality...I had the forks completely revalved by someone who has done a brilliant job on 3 other sets of Showas I've fitted to 650s. He got it perfect. I've jumped it, 2 up, solo, and pounded the crap out of it over house brick sized rocks on steep mountain trails.

    I can't remember what spring rate was in these forks, I mean, I set them up for a 650 and then changed them, I know I changed the springs, but can't for the life of me remember what rate they were. Standard the RMZ rate is similar to the standard F8 rate. I prefer to have lighter springs and revalve the high speed damping circuit to take the big hits, leaving nice plush ride over trail chop. I have solo - 65mm of sag, and 2 up - 85mm sag. It glides over rocks and tree roots, but handles big hits perfectly.

    Best front end ever. I love it. If I bought a new F8, it would sit in the garage until all the parts had arrived to do this exact set up.


    I took the old 0.55 Ohlins springs out of the stock forks and machined down the spring guides in my single chamber RMZ forks, put it all together with a revalve and fitted them back on my DR650.

    2 bikes done. I already had 0.55 springs in my other DR.

    I went the cheap route and just did the springs... About $150(including 2 quarts oil) and a few hours of labor on my part... Incredible difference. I could not even imagine how new cartridges would be.
