[quote=lh4x4;9897918]One poster stated that the 09 up frame had the same swing arm. Absolutely wrong. The new swing arm is a much beefier unit.
Not entirely so sir, just my two cents but I would say it depends on ones interpretation of what is written and from that perspective the statement is not entirely wrong.
The swing arm of the 09 and up frame is indeed still a rubber mount design with the axle passing through the transmission housing and the tranny and the motor as one assembly. The swingarm bearings remain mere steel and the design calls for the requirement of rubber isolators to keep the motor isolated from the frame and no stabilizer was added - still the same! Is the swingarm beefier, yes. HD had to accomodate for the extra added weight to the new frame.
Either way I enjoy my 09 SG even more after the installation of a TT that got rid of my wallow, no death wobble thank goodness, but flat tire feeling in sweepers and uneven road surfaces .
Whether front or rear wobble - I prefer none.
PS - NELS, sorry to hear about your friend.

So, will installing a True Track or other such devices on a 2012 prevent the death wobble ? I waited until after the frame change to buy a Harley and I thought the new frame eliminated the wobble, but apparently, this isn't the case.

Nels, very sorry to hear about your friend.
Apologies if somebody already posted this link, but saw this a while back via another thread on the DW topic.

Guy doing the riding has some big ones to repeatedly take it to the edge.

First of all sorry for the OP loss the reason doesnt change a thing except awareness for all of us. Second I have expirenced a strait line DW on CR 125 5th gear at wot a couple of times, it definatly changed my riding style for that bike. I think the problem was due to fork angle for that paticular year. More of a bounce that created a wobble. This would point to a downforce issue for a strait line wobble. I know when I changed from stock Limited windshield to my 6.5 KW shield my front end stopped walking side to side when passing a Semi at interstate speeds.
I have seen post from Batwing, and at least one RK rider but dont recall any RG's. Any Roadglide riders out there expirience this pre 09 or not?

They all tie the tranny to the swing arm. Mine took 20 minutes to install and I've had my bike loaded two up at high speeds on the freeway through the Smokey's. If I bought a new Harley I'd most likely install one before I needed it just because it's probably the cheapest thing I've spent on the bike.

All of the braces tie the tranny to the Frame not the swingarm, some use the swing arm cap cover like my BaggerHandler. This means that even tho you have a brace your swingarm bushings and all mounts still need to be in good shape and your engine, swing arm, and rear wheel as a unit needs to be aligned to your frame/front wheel, thats why all those mounts are adjustable, if need be take the bike to your dealer and make them adjust and align it correctly.
Odd low speed swappers usually are a reaction to a small rock or manhole cover or other barely noticeable thing, just the right speed and other hard to recreate factors. The tire usually deflects just enought out of its centrifugal momentum to grab on the opposite side of its grip and the snap the bars back the other way, ride a trail bike daily on a gravel road youll experience it enough.

Sheez guys I keep hearing about this wobble on this site but I have been riding 40+ years, owned about a dozen rides over the years. I am on my 5th HD. I had Sportsters, a Softail and last 2 bikes were Road Kings. Sold my 2003 and now ride a 2011.
I have experienced this wobble once in my life but it wasnt on a Harley. It was on a Honda CB750F that was about a month old and it only happened once at high (very high) speed.
I have alot of aquaintences and friends with touring model Harleys and NONE, NONE of them have experienced it either. Yes, we do alot of miles. Being older, maybe we drive slower, less mods etc. Maybe this is a factor???
