I was riding my Ultra about 80 mphon a long down hill sweep (freeway) that is fairly steep...I ride this section of road daily when I commute. The whole bike moved (wobbled) rhythmically down the hill. I have seen several bikes do this (one chopper really bad).

Is this the "Wallow" everyone speaks about?

Or could it be defined as: When I first started riding the bike I felt like the back tire sort of floated once or twice. This was on a straight away with rain "grooves".

Now beforeyou get started I just want to say that I check tire pressure religiously.I have seen several bikes do the same thing down that hill....that was the first time it was a pretty good wobble for me doing about 80...I usually hitthat down hill between 70 and 75.

I at no time thought I would lose controland backing off relieved it. It was nota "front end" wobble or tank slapper.

 

Basically, that sounds like a wallow. Probably caused by the stock Dunflops tracking the rain grooves (they are infamous for that). I've experienced the same thing on a flat straight road with the grooves. It got worse the faster I went.

 

That sounds pretty close.

 

I have felt it front and back at the same time going straight at around 65-70mph, concrete road, no rain grooves. What started it was a crosswind. I was actually going over a bridge. Felt like I was going down, I just kept a steady throttle and rode it out.
Thankfully it hasn't happened since I installed a TXR stabilizer.

 

I described it like the bike having a hing in the middle of it and the the whole frame bent around that hinge point. Just a bit unsettling but nothing to make me panic. My old Gold Wing had the same type of feeling before all new suspension and super brace. I don't feel the need at this point to make any upgrades or changes. I think what you described is the dreaded HD wobble!

Streetrunner, with the TXR stabilizer installed, how does the TXR stabilizer effect the changing of the filter?

 

So is that 80 mph "wallow/wobble" what True Trac is supposed to correct?

 

A Road Dawg with a Gold Wing???? Guess I shouldn't poke fun, we have one winger in the VT chapter.

 

What filter??? Its nowhere near the oil filter....in fact its at the other end of the motor/tranny

 

I experienced that some. But usually on a turn-especially on a rough road. I ride 2-up most of the time. The true track helps a bunch. I had it on my Road King and switched to my Ultra as soon as I got it home. We have a lot of mountain roads with rough pavement. It also helped with what you are describing also. Rather pricey-but easy to put on and well worth it in my opinion.
