    Mine does this also at speeds above 65, but it is usually when there is a strong head or side wind. I have read that the handguards, and front fender are a big cause. Some suggest getting an aftermarket fender to replace the sail that it comes with. Others suggest smaller stiffer handguards, and still others suggest getting a fork brace. The fender is a cheap trial. $30 shipped for my new fender. It is a KTM supermoto front fender which I just got today, so I should find out this weekend if it works. Do a search here or on KLR650.net, there is a lot of threads on this topic at the KLR site.

    Good Luck.

    We're going to need more info. Tire condition? What year's the bike? How many miles? Were the tires balanced? Steering head bearings ok? Ever been wrecked? Air pressure ok? Luggage? How's the suspension setup? Wheel bearings ok? It's going to be one or a combination of the above. Start with the easiest and keep working on it, You'll figure it out.

    Is it something new or did it start recently, like after the new tires were put on?

    Remove ammo cans,

    check axle torques

    tighten steering head bearings

    run full rear preload

    raise forks in triple trees 5-10 mm

    35 PSI in tires while on road

    no death grip on the bars

    I had something very similar happen to my Ninja 250. I had a fairly new economy tire, all of a sudden I got a wicked shimmy above about 55 mph.

    I had a mechanic check the bike over. He said it was probably an internal failure of the front tire, since everything checked out. A new front tire fixed the problem.

    Im thinking it will be the tire aswell as the psi as the pis right now is in the 20s and the tire is a dot knobbie. Can't get rid of the ammo cans as they hold all my shit for school aswell as my rain gear and cold weather gear for just incases moments. Not alot of weight just stuff lol. And I would love to do a scoots dampnier but im short fundadge .. but if you want to donate im all for it :) ill check the sterring steem bearings tomorow and is soon as I hqve fundage im thinking im going to get some shinko 705's For better street manors maybe

    What's the pavement surface like when you feel the wobble?

    Some of the freeways around here have grooves cut into them that run latterly/with the direction of traffic, and they suck big time at speed!
    With my Shinko 244 50/50 tires, it can be downright scary. :huh

    I also suggest that you remove the ammo cans, just as a test, to see if helps alleviate the issue at all. You might also try getting your weight forward like you would in heavy wind.

    I think upping the preload on the rear shock will help a bit as well. The stock KLR suspension is super soft. I'm about 200lb and never could anywhere near the proper sag setting at the back with the stock spring.

    Raise the rear, it will help.

    I just put shinko 705's front and rear (2000 mi ago) on my mostly stock 2005 KLR; other than bar end weights, a front fork stabilizer, and a larger windscreen. I can easily run 80-90mph for 60-70 miles with no vibration (I only do this for convenience). The shinkos are quiet, grippy and corner great. I am 6ft 230# and the stock suspension is soft. This may not help you troubleshoot but these basic mods work great. I run 28psi on pavement.:1drink

    The same thing happens on my new-to-me DR350 at highway speeds as well. It needs a death grip on the bars or else its wicked tankslapper. I havent really looked into it yet.

    Ok so drag is set. I think lol I used some channel lock plyers to tighten it .. seemed to do the trick there not tight as hell but there not as loose as they were .. went took for a test drive got up to 70mph and no wobble. Went to 80 and wow did it wobble but atleast im now able to go faster than 50mph lol will play with suuspension next. Although I do like it soft I am 210lbs I checked today and when everything is set on high/its to harsh a ride. So I don't know .. the po said all the suspension is stock so its all stock

    refresher ..update;;;
    ok so yeah psi raised to 32 ish.... and drag increased .... tires are new ...all i can think of is needing to figure out suspension i am 210 checked today lol but with the rear on high its leand forward and is to harsh of a ride so i dont knoe ill play with that some say its the ammo cans but i cant not have them on there as they hold all my shit i need ( there not for decoration) i have sumo fender so no sail up front

    after suspension im thinking im going to switch tires to a shinko 705 or something of that nature more highway orientated to reduce vibration and chance of wobble

    It is the front fender flapping in the wind. Check tire balance too while you are at it and rim runout. You will be good to go.
