This reminds me of a situation recently. I have an '05 Ultra and a buddy just bought an '07 SG. He was concerned that the bike wobbled through corners and asked me to swap. Now, I rode his SG about 50 miles back from Overton, NV, which is a road constantly twisting & truning, and has every surface imaginable, from washboards to racetrack smooth. I was gunning it, I admit, but on one corner with a bad bump, the SG did a head shake of 3 - 4 wobbles, and for a split second, I honestly thought I was gping to lose it. My Ultra never would have done that, but I run Metzelers and I also checked the rear air suspension for the correct PSI.

QUESTION: Is the SG worse than the Ultra due to its lowered suspension (i.e. stiffer with less travel)? This concerns me because I have an '08 SG on order... I love the look of 'em

 

Also consider and eliminate all other possible problems:

If it is more like a hi frequency vibration type wobble that occurs at a certain speed

each time it is probably tires/tirebalance.



If it is a low frequency wobble that occurs only when it encounters a line, bump,

or in sweeping turns, it is probably a mechanical fault ( loose spokes, loose swingarm,

loose wheel bearings, low tire pressure).



If it is low frequency and pitches the entire bike side to side with a power of it's own

like a pendulum (tank slappers) and happens when the bike encounters longer G-out type bumps

(especially in sweeper turns) it is suspension geometry from overloading or sacked shocks/springs,

or improper suspension settings, usually from excessive sag in the rear

 

I installed a Ridestr8 on my 06 SG. Also added progressive 440 shocks in stock 12" length and progressive fork springs. I'm just used to progressive products. I know there are other mfgs. Now no more wobble in sweepers. Unfortunately I have now dragged both driver floorboards and scratched the bottom of my mufflers. But D**n does this bike handle nice now. Had to upgrade the brakes to slow her down better. I highly recomend upgrading the suspension.

 

I don't know, but my SG wasn't bad at all before installing the Ride Str8. I did get some minor waggle in sweepers with irregular pavement, but it wasn't ever unnerving. Some have said the lowered suspension makes the bike more stable, but I can't say. My last two bikes have had lowered suspensions, my old RK having stock shocks with a 1½" lowering kit. I had very little sensation of waggle on that bike, but it did exist.

 

i just gas it and it goes away

 

iclick, thanks for the heads up. I appreciate it. As I say, the SG looks fantastic. I mean, you've got your SG all "ultra-ed" out and it still looks way better than an Ultra in my humble opinion, and I think I'm qualified to say that because I own an Ultra.

Thanks to FLFOOL for the understanding on the different types of wobble. That all makes sense.

Funny thing is, I also own a couple of Beemers (one a sport tourer, the other is straight sport) and while these handle great, I can still give a lot of the other riders in my a group a run for their money even when I'm on the Ultra. Plus, while I like ALL bikes, I really enjoy riding the Harley the most. The sound, the feel, the wind in the face... it's all good!

 

I have the TXR, and have it it on for quite a few months and almost 1000 miles. It's a great product, and let's me scrape the floorboards with confidence anytime I want too. Getting it adjusted to the riding style you want is the most important thing to do (don't just have it installed and leave it at the installers setting)

I just got a RideSrt8 from Bart. Should be intalling this week.

 

One reply was, "gas it, it goes away..." In 2001 at Sturgis, a group of us were hotrodding from RushNoMore Campground on the interstate heading into town. I was running down the Softail Deuce when he started a high speed wobble. He gave it to her.... He was violently thrown off and I'll never forget the expression on his face as I went by him with him on his butt, legs straight.... you get the picture....
Moral? I believe all Harley's suffer from a high speed wobble. I have a truetrac, it helps, some... If it happens to you, I suggest lean forward, grab a handfull of handlebars, slow down, and, oh yea, the most important part, PRAY!

Can someone post a photo of the Ride-Str8 Stabilizer Bracket Kit installed?
