UC aerodynamically stable
On my 07 UC that has SYN oil & Stage I, I removed the lower fairing to check if it would lower the thigh burning heat. The additional air is a big plus and most certainly lowered it. I also received a suprising benefit (NOW I KNOW that many UC riders will take issue with this) the bike now glides through the ride with no swaying and is aerodynamically stable.
With lower fairing on, MY bike swayed in the 70+ range, with the farings removed on the same highway it is stable.
Note: I said MY bike....

RE: UC aerodynamically stable
I cruised down the highway today at 90-95 mph with no problems at all, one handed most of the time.
The only time I notice any unstability in my ride is when pushing 100+ and having to corner.....you can really get a wobbly feeling.

RE: UC aerodynamically stable
Interesting. I didn't notice the aerodynamic sway with my lowers on my 07 Ultra. What I did notice was the wind buffeting coming off those lowers.
I took the lowers off, and the buffeting was reduced greatly. Still had a little, but not as much.
So, while I was at the dealer having a new rear tire put on I had lower wind deflectors put on. Put them on my Softail and they worked great.
Strated riding home, and all of a sudden I get an aerodynamic swaying. WTF???
This is not good!! Doesn't do this on my Softail!! Buffeting is gone, even with a headwind, but this strange swaying.
I think the dealer put the wind deflectors on wrong.
When I got home I checked my Softail and sure enough, they are opposite of how they are on my Ultra.
Now the big question, do I just fix it myself? Or take it back and let the dealer do it right?

Here is how my bike is setup & mine handles perfectly at any speed, the only thing that doesn't show in this pic is the fork air baffle on the lower triple clamp.

RE: UC aerodynamically stable
OK, is it the batwing, the lowers or the shocks that cause swaying???
I have an '05 Ultra that exhibits swaying at highway speeds when the winds are ~ 20mph.
I always thought it was related to the "wind" speed. Does not happen on a calm day.
Now I see above there are other theories.
Can't believe it is shocks - I have $600 Works Street Trackers - but I do run them on the "softest" setting.
And a coworker friend of mine just switched his '07 order from a UC to a RG because of the exact "swaying" issue.
Appreciate the insight.
THANKS!!!!!!!!!!!!!!!
