When I got my new dakar home noticed the genius dealer mech didn't align the rear wheel and I had some head shake coming out of corners on the throttle...I used a set of digital calipers to get it close enough and now no problems.

Mine does the exact same thing starting at about 80mph. I'm really thinking/ hoping that it's the tires. If I go to pass a car meaning accelerate quickly from 55 it'll start shaking or weaving pretty bad. If I accelerate at a much slower rate then I might be able to get to 85 with minimal shaking or weaving. I bumped the tire pressure up a little from where the dealer had it and it might have helped some.

As far as the scraping noise mine also did that after I removed the upper fairing. After I had reinstalled them the noise appeared. One of the vent hose clamps was rubbing the left fork. Readjusted it and fixed the problem.

I've read all of the post about people going 100mph on this bike and I was thinking no way. So I really think it's the tires. I'm swapping mine out soon for an upcoming trip.

Normal for a brand new 908, they will scare the crap out of you till the wear in. Try lowering the rear tire pressure to give it a larger footprint. I noticed an improvement after 4-500 miles.

Similar issue I had resulted in a bad end. Ended up installing stiffer springs in front end....so far no repeats

+1s for two posts

First, wait 200 miles and the tires will get better.

Second, shake in the front end is often issues in the back end.

i dont think it is something serious with the front end, these bikes get setups that do this now and then. It isnt the design, i have run my bike to 200 kph, granted easier with Scorpions but my knobbies easily do 180. Do check your rear alignment. Suspension adjustments are a big step but stiffen front, soften rear to see if it helps.

Balance tires before changing.

Glad to hear it's not just me, mine does it at 65 mph, a good firm grip on bars and it holds tight, I'm running 20 psi front and rear and that helps a bit. just over 300 miles on her. As I got more mph it smoothes out, it was not bad at 105 mph just scary getting there.

Mine does it too. It's gotten better after 1500 miles, but it's still there. I don't think the 908s are the best on road but they sure are good off road. I'll add a steering damper later on when I have some spare change.

Talked to a buddy who said the springs in these bikes are really mismatched. He told me to run way less rear preload than what KTM recommends to help stabilize it. He also suggested getting heavier fork springs. I'll adjust the preload in the rear and head to the dealer in a couple minutes. I'll have them check rear wheel alignment also. My buddies 990 Adventure R doesn't shake like mine, so I dont think it's a manufacturing defect. Combination of tires, suspension, and steering bearings I believe.

Scraping noise wasn't the steering bearing bearings. A little tab was scraping the triple. The steering still feels loose, so they will tighten it up a little. I am putting on a T63 they have in stock.

These big girls are pretty sensitive to what tyre is on the front of them in my experience (100,000ks or so), especially with new knobbies.

Changed to the T63 in front and the death wobble is gone. Screw that 908 for highway riding. I'll save it for when I go to Colorado. I'll just carry it with me and swap tires once up there. I did 80-85 mph for 30 miles all the way home. A few blasts to 105 or so. It had a slight wobble at 100+, but just barely. Now I feel okay with putting a damper on it.

I missed you had a 908 front, IMHO these are terrible on the front of these - they do feel better with about 600 miles on them but still crappy and I don't think they are much better on gravel, but I suppose you need to wear it out.

My favorite knobby on the front is the Pirelli Scorpion Rally (not the 50/50 Scorp, but the knobby one) good grip no head shake. The TKC 80 is okay to, better on paved, not so go on dirt.

Edit: I have done up to 200kph on hard packed dirt roads and 170kph on loose gravel roads on Scorp Rally with no head shake (and no steering damper).

908RR fronts are a little vague and wander for the first 150 miles then are fine for me. I like them better than the 606 and no pinch flats They are not the best choice for a commuter bike

Yay! I hope the same is true for me in a few days when I go through this process! I'm glad I was sorta right about the issue too, lol! I was starting to think I gave you bad advice in the first place, lol! Wish me luck that it's a simple solution for me and just a "snakey" 908RR. If the wobble goes then I can mount up my hardware! Cheers!

Had shake

I have the same bike with the same problem. I also have a 19/17 set of wheels for street. With the street rubber on it does not shake at all. I would suggest that it is a tire problem mostly. I have also installed stiffer springs in the front forks.A steering damper is going to be my fix I think. Just trying to figure out which one is best bang for the buck.
