Bike sways at 140-150km/h (85-95mph)

Hi all,

I was just wondering if this was typical of the KLR 650 when it is up at 140-150km/h the bike sways in an unnatural way, I have had the wheels balanced and they are perfectly in line. Its a strange sensation it kind of sways constantly like a mild wobble. Thoughts?

I think the only way my KLR would go that fast is if it were dropped out of an airplane, LOL. It certainly wouldn't go that fsst with ME on it.

So, sorry; I'm no help.

While I may have had my KLR that fast once or twice, I'd recommend going slower for sure.....it's just not meant for that kind of speed. As far as the why, at that speed, I'd suspect aero. Here's my "wobble post"

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

Hi Dave,

Thanks for the post, as long as it was a known point on the KLR.

I'll suggest there are too many variables to list, the total possibilities of the KLR Waltze, at interstate speeds.

To me, KLR is a much more satisfying and enjoyable ride if I keep it at 65 or less.

I experienced a sort of swaying a few years ago. I was not going fast, mostly 55-60 mph, through twisties, fully loaded for touring/camping. One of my lower sub-frame bolts had come out.

Hiya Rossi, mine used to do the same thing at a corrected 80mph or so. For me the fix was simple. I went 78mph LOL. Ive had bikes that Ran almost twice that fast and then I got old! Now, a KLR at 75 Suits me fine.

Cheers
