Living with the wiggle ?

    I bought a Klx300sm. Great fun, light, easy peasy to ride.
    At speed on the highway (80 mph +/-) a slight wiggle begins. Like a modest left right oscillation. At first I just attributed it to the pie slice stock mirrors or the handguards that I installed. I removed them and no change so I put them back on because I think they look cool. Then I noticed chain was needing attention. I went to adjust and saw the alignment of the axle was off more than I thought was acceptable. I figured maybe that was causing the weave. Adjusted chain aligned axle went out for a ride.
    Wobble still present at higher speeds and still slight. Until cross breeze's enter the equation. Then the intensity of the weave increases.
    So basically what I am asking is this ...
    Is this the way dirt bike steering geometry works on paved roads at speed ? Or do I continue questing for a solution?
    Thanks

    Try changing tires, tire pressure, and dropping the forks in the triple.

    On my KTM, it's the lousy aerodynamics of the plastic front fender.

    They are going to do that especially with side plastic shrouds and dirtbike style front fender. Also, why the efff are you doing 80 on a 300cc motard bike? LOL that thing aint made for that.

    The wider bars can also can be a bit more sensitive to rider input at speed.

    I"m a little surprised a klx300 will do 80mph. Is that indicated, or actual?

    Yep they all do this, depending on what tires, fender/bodywork, and suspension setup.
    Adding some preload to my rear damper on the drz helped slightly, a tire change almost eliminated it

    Traffic flow on the GSP really demands 80 mph or your a hood ornament.

    Edit. Ty again for the input peeps.

    My old KLR650 would do it at anything above 70mph. It was the front fender. Cut it or brace it, and the oscillation will stop.

    My WR250R does the same thing...I agree with others that it's probably the front fender and radiator shroud aero....

    Dropping the front will help but quite simply get a good steering damper on it and live with it.

    I haven't looked at how the KLX fender mounts, but on older KTMs that had all four bolts going into the clamp from the bottom my friend would advise shimming the front ones with a couple washers to tip the fender down.

    Why not just pull the fender off and take it for a spin to see if it goes away?

    My WR250X/R does it too. Nothing that I tried will get rid of it

    remember... that thing only has a quart of oil in it. long drawn out high speed, high rpm riding will dry the clutch right out and fry them. lots of supermoto/supersingle guys found that out racing, riding at the big tracks. Ski

    The KLX300SM is designed to be a street machine from the factory...
