speed wobble

change your triple clamp offset from 24mm to 22mm to increase trail.

the seat pan won't flex as much...
If someone could post pictures of the additional supports, we all could benefit from KTM's substantial R&D investment.

So what can I do to cure the wobble???

K
1. Is it consistently the same on different types of pavement?
2. Check tire/ air pressure/ balance
3. Check suspension/ forks
Wobble worries me because if it's happening on say smooth asphalt a bit more kinetics (such as rock, rut, etc) could set off the nasty harmonic known as "Freakin' Death Wobble"! aka. headshake. And I hate it when that happens. Especially at 70mph.

Sometimes simply squeezing the 'tank' with your knees keeps a bike 'tight' and reduces/eliminates shimmies/wobbles.
Thats worked for me on many bikes over the years.

1, Yes.
2, Happens at different air pressures (22, 28, 32)
3, Suspension is about to be sent out for revalving, reshimming, respringing for my MASS and my camping load.

Worries me also...

Squeezing the tank will get rid of it as well as tensing up on the handgrips.

Yeah....when I get a high speed wobble I do that....my arsehole also tightens up significantly and grips my seat a lot tighter.....

Isnt the wobble just the joy of having knobby tires?
My GS wobbled too with knobbies on pavement.
The steering damper helped.
You can ride my bike and see if the damper helps you and if you want to invest in one.

Re wobble at 70: Check the alignment of your front and back tires and check that the distance from swingarm pivot to axle center is the same on both sides. I did up to 80 on pavement using Michelin Desert tires which have aggressive knobs not good for the street and no wobble. Stock(steeper) steering head angle.

Technical responce from my ktm mechanic about the speed wobble was "yeah they do that" - full fuel with extra luggage plus a damper turned up gets rid of it remember to turn damper down in dirt tho found that out the hard way
