    I talked to the mechanic who also owns a 990 and he put .70 springs in the front to combat the issue.

    Jeff Slaven told me to run .62's in mine. I don't think the stock valving will be able to control .70's. That seems too much unless you weigh 350+ lbs. I'm 275 and will be having the .62's installed next week during the first service.

    I have a Scorpion rally on the front (with HD tube) no head shake at all. Just did a 3000km + trip mostly dirt however some 100kmh plus tar, good grip in all conditions and no issues. Also have a ralle moto damper and while this is one of the best things that I have ever put on a bike it will not fix a tyre issue including alignment or balance.

    Ps When the Scorpion rally is done I will go the same again, used to have 606's on my 640.

    I have the same bike as well. It shakes its head severely at highway speed. I have a 19-17 combo set up for street and it is fine with that set up. The stock tires are brutal! However they are a must off road.I have ordered a steering damper from pro Moto billet and will report on that when it is installed. I have also installed stiffer springs because the stock ones suck.

    Hey Jon, just an update for my head shake. Gone with a bit of adjusting to the forks. I'm still gonna go heavier for springs and stretch them a bit, but it's all better now! Today = some new tires and doodads too, :)

    Let the 908 break in a little and the head shake will go away. It's almost a universal occurrence. Put 908 on a 990 and get a weave at speed. As they break in you can go faster and faster before it sets in. Suspension does help but ultimatly its the tire. Suprised KTM mounted them stock with as many people that have experianced the issue.

    On a side note they are a very stiff sidewall tire built for heavy rally bikes. The beifit to this is they help protect the front rim when all that weight comes smashing down on a rock at speed. They also seem to hold up well under the Adventures. I got about 5k miles out of my front ran in conjunction with a Mefo Super Explorer rear. Good combination for me. Currently it's on full set of 908s. Going to try the Pirreli Rally next. Heard they don't weave when new and also hold up well.

    Also quick bit of advice to the new owners of 990s. Invest in a sidestand relocation bracket before you do a lot of off-roading. The sidestand is mounted to the engine cases. One inconvenient hit on a well placed rock and its an expensive leak to fix.

    And the bike is willing to go through a lot rougher terrain then you think. Most fun bike I've ever owned.

    I've already traded my 908 front off for help installing fork springs and doing my first oil change. You like the Mefo here in the Arizona desert? I ride in loose sandy washes and rocky trails. I'm just west of Phoenix off 331st Ave and my buddy also has a 990 Adventure that lives in Verrado. We should go ride sometime.

    So I just completed a wet and snowy 1100 mile trip with new Pirelli scorpions and I'm happy to say no head shake. Set suspension to sport.
    Secondarily I invested in Sidi crossfire boots and klm Badlands jacket and pants. Bone dry and warm. Worth every nickel

    I do like the Mefos. They seemed to work well for me out here. I ride a lot in The Florence, Superior, Globe area and sometimes out to Young. Lots of rocky trails and sand. Not quite the traction of the 908 but I'm sure it won't last nearly as long as the Mefo.

    I live in Casa Grande, definately should ride sometime. :deal

    I must admit I raised my eyebrows when I saw the Baja edition being sold with a front 908RR. The rear is bad enough at making the bike dance around, but the front is even worse. It's been talked about to death, but the front springs are too soft and a re-valve to go with it works wonders. As for the back, the rear spring is too stiff and also a re-valve to go with a softer spring also works a treat. That will help immensely, and even after that (not that I'm a huge fan of them) a steering damper is also required for these if you want to settle it down off road / sand etc. It's all good if you know and you're prepared. It's money well spent in any case, but it would be nice if it was more balanced out of the box.

    Oh, and back on topic, yes, the 908RR front will make it dance around quite a bit. I wouldn't recommend it. The Pirelli MT21 and the Pirelli Rally Scorpion are great. I never tried the T63, but if you're happy with it then that's great too.

    Not too sure if they got it better on the 1190 ...

    1200 miles later Jon, still no headshake. In Seattle now, sand dunes in Aberdeen tomorrow, woot! Should be fun as my Emig is sitting at home, lol!

    Edit: my Klim badlands jacket sucks though. Snow storm on the way here with major rain... Leaked all down the front and on every zipper. Lame. Going to be looking for a different suit when I get home.

    Right on. I just installed the .62 fork springs today and did the first oil change. Now I need to go test it offroad. On the highway home it was stable.

    I am sure the suspension could use some tweaking; however as said, the front 908 is not a decent road tire. My local dealer told me he would not put the 13 out to demo with that front tire because it was dangerous. That said a lot to me when the dealer actually said something negative about their product. Well at least a product on their product.

    How is the bike riding now after a few miles on the T63 we put on?

    BTW...I spoke with KTM today...apparently they "forgot" to include the Supersprox rear sprocket from the factory. I am doing a warranty claim and ordering the sprocket today...FYI to any others who purchased a '13 Baja and did not get the rear sprocket.

    Remember the sidestand relocation kit I told you about, also mentioned earlier in this thread, very important!

    It rides great with the T63 front. Thanks for getting the rear sprocket taken care of.

    that sucks. i just bought the badlands pants to go with my rallye 2 pro jacket.. i have never had a leak in either of them, with the disclaimer that the pants havent had major storms yet. but the jacket has been perfection in any weather. and the jacket was to be the replacement if my bmw one wears out..

    Just put the first 600 miles on the new bike. Ran about 100 of those miles of dirt. Lots of ancient bad tarmac in rural Montana. Tight twisties. Mountain roads. Ran up to 85 mph on smooth pavement. Yes, a bike with aggressive knobbies will track grooves and squrim around. This is normal compromise to have dirt capability, IMHO. If it freaks you out slow down and get more riding experience. Also wondering about people whining about wind buffeting. Yep, a visor on a DS or off-road helmet is not smooth in the airstream. Guess I just have ridden so many difficult conditions on all kinds of bikes in the past. Try no wind protection on a naked bike. Everything on a motorcycle has design compromises. My new Baja is a dream machine out of the box.

    The badlands pants are great actually. Just the jacket leaked. They are replacing it :)

    I miss my Rallye 2 suit though...

    "The best you know is the best you've rode."

    I, too, notice no buffeting and the tires I notice, but am comfortable with. Everyone is different though and for some riders a squirmy bike on pavement sucks balls... I say ride what feels good! (You're damn right the 990 is a freaking dream out of the box... Been dying for one for 10 years and now that I have one someone will have to pry it out of my cold, dead hands to get it away from me!!!)

    Ok, I know how to ride, not scared of headshake, but it was ridiculous on my new 990 Baja, just installed pirelli scorpions and all of the headshake disappeared totally. Smooth as silk!
    On my 950 adv I had MT 21's there was no headshake but yes not as smooth but amazing off road. The problem with 50/50 tires is they suck at everything!
    I just scored the scorps with complete wheel set attached :clap, so i will get some Mt 21 for front and rear and just swap when needed!

    PS. remove the abs plates before swapping the new wheel sets or it will chew up your speedo sensor! :lol3
