Default Weave on highway

Last few times I've rode on the highway there's been a couple time that in long sweeping turns at 75 to 80 mph I've gotten a rear end wiggle or weave. If I slow down it goes away. Just wondering if anyone else has had this and possible causes. Air pressure is good rear tire has less than 1500 miles.

And I thought from the title someone lost one or more of those hair weaves on the highway and the poster had to avoid it or something like that.

Those things can be slick with oil and if you don't know how to approach them you can end up having to lay the bike down...........................just saying

Shocks. Swingarm bushings. Neck bearings.

Those would be the first things I’d check in no particular order.

The touring bikes have been plagued with a wobble like you describe for years. There is a good post about its causes by "grbrown, Bagger wobble exposed!". It has to do with the mounting system used in touring bikes... It doesn't apply to softails, but it is caused by components flexing in the rear end due to the mounting system..

I have never felt, nor have I heard/read of a rear wobble on a softail.... but like in the baggers, it makes me suspect you have something amiss in your rear end components..

If I were you I would carefully inspect the rear end components...

Tire
Wheel
Wheel bearings
Rear wheel alignment
Rear fork pivot bearings
Shock mounts


Good luck and let us know what you find...

Laced wheels? If so check your spokes.

As above along with body position, grip on the handle bars (arm position/pulling/pushing/tight grip because of the speed), head position, rear shocks too soft or not adjusted correctly, front fork tubes shock sliders worn, front tire air pressure (did not state), track/trail/rake changes made to the bike, lean angle change if body position is shifted, aerodynamics if a front windshield is present, road surface changes (pitch, cracks, tar snakes).

You stated "air pressure " is good. What might that pressure be?
