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.

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.
