With all the debate and mis-information we get in HDF on bagger wobble, and all the other things it gets called, I thought it was time to describe the cause of it. I posted over in Touring, but no apology! Follow this link for a jolly good read!
Even after seeing it consistently appear in the video, someone will get on here and deny it happens.
Very true, always a few that will deny something until it happens to them, then some will still deny it......
I rode 'other' brands of bikes for 30 years before I got my Harley, and the handling was very evident right from the start. I was told that is is normal, no problem, just ride it. So I did for about 6000 miles - then I put new tires on the bike and it amplified the issue greatly. Installed the Progressive suspension brace and it is night and day better. But I can't tell anyone about the solution because they never see a problem - mostly because the bike they have is the only one they ever rode and don't know any better.
Good article: well written. For those of us on hard mounted engines, some still applies. Coming back from a 1800 mile ride, with the bags loaded heavy, I experienced a "wobble" around 85 on a straight road ! Thinking it's time to look at the swing arm setup.
This isn't a denial...i promise. I do have a follow up question. I've never experienced this wobble. Now to qualify that statement, I'm only have about 12k of experience on a bagger, and I've never been accused of pushing the envelope with my riding style, I'm a cruiser for sure. Does this normally occur with more aggressive riding (not suggesting it's the riders fault at all, but acknowledging that there are definitely different riding styles, all of which are perfectly acceptable).
There are two aspects to this. The 'wobble' or 'rear steer' are most obvious at speed, especially in a bend and when hitting something that upsets the bike's balance. This can cause a momentary shift sideways of the rear wheel, which corrects itself, but in the meantime gives the rider kittens. Not nice.
At lower or less adventurous speeds, the rear wheel simply does not follow the front wheel as faithfully as it should. While a shrewdly chosen stabilizer kit will correct the wild moments, it will also tighten up the steering, give better feel and make the bike a whole lot nicer to ride. All the time!
Thanks for the video Tom, some real butt clenching moments there. Have to admire the cop for doing that repeatedly. I think it was somewhere here in HDF, a good while ago, that someone posted a link to a Police report about comparison tests on several candidate Police bikes of different brands. Made a good read and left me wondering why Harley doesn't make a better effort to sort their bikes.
The fork legs need better support in the top tree and the rubber mounts need better support. There, that wasn't difficult! There are solutions for both already out there in Customland.
