Because we can!

 

I recall this happening once in 50,000 miles (Maybe another time but insignificant as I don't recall the details). Between Cherokee and Sylva NC, heavily loaded with gear, long sweeping uphill right turn at about 65MPH. Only lasted a couple seconds and was remedied by easing off the throttle. Knew what it was ONLY from reading this forum.

Not a tank slapper, but an uncomfortable lateral gyrating effect at the rear wheel...Maybe about four cycles per second.

Thought the problem was remedied with the new frame?

 

The new frame is far, far better than the old one. My wife and I rented a 2007 Road King in Ireland that was bound and determined to throw us off, my 2010 Limited was never that bad.

But the basic flaw (swingarm attached to transmission attached to engine attached to frame by rubber) is still there.

 

Man I have a 2011 SG and I have never had an issue w wobble, however, its good to know especially at higher speeds which I normally tend to ride in the upper 90+ at times... No room for error at those speeds, NONE!

 

I agree with the faring issue and wind. last year when hurricane Debbie was coming in we were crossing the inter-coastal water way to dolphin island ,Alabama wind gusts were about 70mph . had to slow to 40mph . any faster and it felt like I was being pushed around by a gorilla side to side. had the bike checked and everything was fine. wind is usually not that big an issue. the wind at the speeds described would probley be similer

 

That is the master-piece of the design! The flaw is omitting the rear stabilizer in the version that we get. The original patent had it, as does every Buell and rubber-mount Sportster. Read the link I gave earlier.

 

 

yesss and with an ape, 21" and loud amp radio playing


Grbrown, your thread on wobble is great

 

Why would anyone want to do 115 or 120 mph on a bagger? You can't stop it or turn it and anyone who thinks they can has never pushed a late model rocket in a corner. Would you take a Winnebago to race track, 900lbs bikes are not made to corner at a 100mph and that is why rockets don't have tour-packs... If you want to go fast go get a gixxer.

 

Thanks for the comments and suggestions. Grbrown, I read your previous explanation, and that is the best, most concise explanation I have read. Thanks! I have read alot over the last few days, because if you experience the true wobble it will change your riding. What I experienced was not handle bars wobbling at high speed with no hands, this was a severe swing of the rear end, like a pendulum, exactly kinematics. It did not stop in a few seconds, it lasted a minute or so until i gradually slowed down...wondering wtf just happened. Yes, I was riding hard, I accelerated out of the turn at close to 90, but I have been riding like this on other touring bikes and never experienced this. It was disturbing, as I pride myself on riding fast but safe technically, never out of control and then wham, I m being slung back and forth at high speed. I hear you all regarding riding heavy touring bikes hard, but I have found them to handle well up to this point. I think I will add True Track to my bike. Should I have the neck bearings and wheel bearings checked, as it is a new bike, less than 1000 miles? Thank you all
