FWIW, here's my standard "wobble post", though I'd note that it deals with the common high speed wobble more than anything else;




Way too many people think that addressing the symptoms by dealing with handguards, fenders, fork braces, etc. are the answer rather than dealing with the real issue which is related to suspension setup and loading. I'm not convinced that the KLR is any more susceptible to instability than any other bike with long travel, lightly damped suspension and the Owner's have a propensity for severe and uneven loading.

There are some problems that need to be checked;
- bad/lose head bearings
- condition of wheel bearings and suspension bushings
- wheel and tire condition and appropriate tire pressures.

.....beyond that, It's settings;
- proper sag settings and adequate damping
- proper bike loading
- avoiding inappropriately un-aerodynamic loads

addressing the symptoms rather than the cause can help but IMO shouldn't be done until all the aforementioned items are checked and corrected if necessary. Nonetheless these can help stability;

- fork brace
- smaller fender or lowered fender (I use a polisport as I hate both the supermoto and low mounted fenders)
- consider tank bags instead of putting everything in huge panniers which affects both weight loading and aerodynamics.


My 2001 had some high speed issues that went away as soon as the sag was set properly....and after my Cogent suspension was installed, both my KLR's have been rock steady.....even with full knobbies and low tire pressures (20 - 22PSI). Lastly, as others have mentioned, the rider also plays a part; keep a relaxed light grip on the bars and don't tighten up. Changing your position (move forward/lean forward) can help too.

2 cents,
Dave

Moving forward helps on mine. Especially on the Dragon. I hug the tank on the Dragon and I'm too busy to notice any wobbles. And that doesn't help any with the o.p.'s issue - slow speed wobble - and mine is more of a weave. At low speed the bike slightly veers left or right and must be corrected and then it slightly veers in the other direction. On my NEW '17 the service manager rode it around the parking lot and said it was steering head bearings (it REALLY felt like that) , but the bearings were fine and properly adjusted . Other people have had the same thoughts and no one has found a bearing problem. None of us want to spend big money on Cogent suspension only to still have the problem.
If someone knows someone at Cogent and can ask if they have heard of this problem .....maybe they have and maybe there mods fix it. THEN I imagine I would be heading for Cogent.
Until something else comes up I'm gonna try another 1/2" lower with the forks.

Two things;

- What you're describing REALLY sounds like the steering head bearings are too tight.....I had the exact same feeling/issue when mine were overtightened - it doesn't take much.

- spending big money on Cogent suspension has benefits that go far beyond the steering...give Rick or Todd a call though and they're always happy to talk suspension.
