    I felt the same way when my R was new w/ stock tires. However after switching to knobbies and running lower pressures (about 18psi highway), the bike tracks very straight on the interstate @ 75-80 mph. So, I think the choice of tire and tire pressure can make a difference. Agree the R is not a highway bike though.

    When I put the Shinko 244 on the front (and rear) I got lots more head wobble. I started at 12 psi, seemed fine otherwise. When I noticed the beginning of cupping, earlier than I had hoped, I adjusted pressure to 18 psi. Head wobble decreased. I still get it some in dirty air. Mine is a WRR. I stay off the freeway usually too. 5k miles on those tires now.

    Mine has been great on the highway. I've had it up to an indicated 90mph and it felt pretty stable. That's on stock rubber with pressures between 15 and 32. Much better than the '09 KLR650 I had with Kenda 270s. That was scary at anything above 60!

    Mine is rock solid on the highway, for a little bike. My KLX250S was downright scary at higher speeds :eek1

    I had exactly the same the feeling when I bought the WRR new with Trailwings. After I set the rear shock to it's minimum height and raised the front by putting the fork tubes 5MM below the top clamp, she is stable up to 90 MPH. Yes, 90 MPH is going downhill.:D

    Of course, that's with 21/18 tires. Maybe 17/17 would be different, but 10 minutes spent on re-setting the heights might be worth your while.

    i run the AC-10 front and a D606 rear and do 500km of highway a week mostly at 110km/h and i find it better than the DR650 i had.......with torque being the only exception on Big hills

    That is a good point, BluePill. Now that I think about it, I lowered the rear about the same time that I switched from Trailwings to knobbies. In my case I was trying to make the bike a bit less twitchy on gravel (and lowering the rear helped) but it probably changed the handling on interstate as well.

    Thanks for all the input. I think I might have had a strong headwind the other day too, since at times the bike wouldn't pull past 74, and passing semis was interesting. And the cars i passed probably got a good show. Just kept a loose grip and rode it out. No biggie, was just curious of others' experiences. But bottom line is freeway sux.

    When I had the twitchies, it was usually with head or cross winds. All gone since suspension changes 4 years ago.

    Strong headwinds/crosswinds when I had the stock tank on were bad.

    After putting the Safari tank on (and keeping it full) the bike tracks so
    much better. The extra weight in this case helps.

    On highway stability: I think your tires, tire pressure and whether your wheels are balanced are the most important things to consider. I rode a stock WR250R last summer up to ninety-something mph (indicated - so probably mid-eighties) and it felt pretty solid. My current WR has unbalanced wheels and the resultant periodic oscillation is the most unnerving part about taking it over 50mph.

    You could try setting your forks low in the triple clamp or (theoretically) adjusting your preload to try and pitch the bike upwards if you can. That's what Harley riders do when they want their bikes to track straighter. Keep in mind this will alter your cornering characteristics - your bike won't stay leaned over as easily since it's no longer neutrally balanced, and you may feel a sudden affinity for chrome. That's my understanding, anyhow.

    Anyway, I don't want to thread-jack but for the record (read: not important), I'm not comfortable doing 75mph and I don't think I want to be comfortable doing it - that's why I haven't balanced my wheels. Yeah, I get jiggled a bit and I probably even give up some traction from the bouncing but I gain a lot of awareness and paranoid alertness for when a two-foot diameter bucket rolls out in front of me (true story - I braked and then swerved). I don't like highways on my woods WRR, a stock WRR or a BMW K1600GTL for that matter. Even doing 65-70mph for any considerable length makes me queasy. There's no empirical data to suggest that light-ish bikes are demonstrably less safe on the highway - they just give us a more dramatic representation of the immense kinetic energy we're carrying at those speeds.

    I have got that wobble on my KTM 950 with TKC80 DOT knobbies, my wr250r with the oem deathwings, and my new 690R with Pirelli MT 21 tires. It only happens at high speeds and seems to be a a function of the turbulence hitting my shoulders compounded by the round cross section of some tires.

    Sitting back and relaxing your grip will help a lot. A steering damper will help too. But the best fix is a front tire with a triangular cross section.

    My WR250r settled down when I went to Michelin T63 tires. I ended up never buying TKC80's for my 950 again, and never had the problem resurface. I have a steering damper on my 690, which is good up to about 90mph, but I can feel it coming back above that.

    I ride long distances on Interstates or high speed highways because I travel with my bikes.

    got some new seal savers in today....superfast & easy install with the new zippered model as i would admit, i wasn't going to pull my tubes just to install a pair! zipper has a rubber backing to protect the tube from the zipper...so far so good (just on the street)
    i like the look & for $25 hopefully they help my seals last a bit longer! i havent zip tied them up yet, fyi
