Default Front Wobble - Superbrace

I was riding down the concrete slab the other day and noticed some slight front wobble when I hit 80 mph...not sure if that's happened before but it was the first time I noticed it and I think it was from caused by crosswinds.

In any case, it wasn't the wobble of death or anything and manageable but still just to be on the safe side, slowed down to about 70 mph until it was gone.

Started doing some research as I've always wondered about front braces and it seems generally the reviews are pretty good so I ordered a set of superbraces for the N. Figured it could help with the crosswind wobble and since my favorite type of riding is in the twisties, maybe it'll help handling the curves a bit.

From what I've read (I'm just the messenger here so don't take my word for it) it seems like the 39mm fork tubes will benefit from a front brace more so than the 49mm fork tubes. Makes sense since the 39mm ones would bend out more easily than the thicker tubes. Also seems to be the general consensus that this helps for hard braking and riding the twisties but for just puttin' around town, doesn't do a damn thing unless you like the looks (personally, if there was no performance gain, I think the front looks better without it).

In any case, excited to see how well they do when installed on the bike and I'll post some reviews when I get a chance. If they're completely worthless, i'm sure someone who thinks they look cool won't mind taking them off my hands in the classified section

I starterd getting a wobble when my front tire had about 12k on it. I've heard from others that have experience similar problems at approx same miles.

jbyun,,you did your homework, what you found out about fork braces Is on the mark.

A fork brace should be the last thing done to enhance handling never the first.
It could Hide a potential problem.

Proper tire pressures for you and your bike are not always the manuals 30f/36r.

I doubt 1 in 100 motorcycles have rider suspension sag set correctly.

A sagging front end can reduce effective rake and cause a Hi-speed wobble.
My 2008 1200R with almost no miles on It at the time of purchace had 50%
rider sag up front and a nasty wobble powering out of turns and going off
throttle on the Interstate.

Most front end wobbles are put Into the bike by the rider.

All motorcycle front ends have a slight unpreceptable wobble, It's the nature of a
two wheeled vehicle.
When a rider Hangs on tight to fight wind blast or death grips the bars or
stiff arms them he Is amplifying any natural or occasional wobble and transfering
It right Into the chassis.

I have the Screaming Eagle fork tube brace on mine about a 1/2" above the fender on mine. most of my riding is on the long and straight so it does help to balance the front for me, however, when im in the twisties, it does take a little more effort to bend the bike over because it wants to stay upright......thats my experience with it.

i've kept quiet about my superbrace so far but i will now mention what i have found.

when i installed mine a few months back, on my 2010 iron, i felt absolutely no difference.
the front will still follow tarlines just as much as it did before (though it never did very much to start with) and behaves no differently in corners or braking or even just sitting on the sidestand for that matter. the brace seems like an inert piece of metal riding along with me.

i hope that because i had only a few thousand miles on the bike at installation that the bike was still tight and that improvements would have been more noticeable if it had already had more miles on it.
but part of me feels like i bought snake oil.

ymmv

edit:
i want to be clear that the superbrace was not installed to correct any problem. my bike rode/handled rock-solid.
i installed it as part of my effort to improve ride quality. through my reading here and on other forums i found that with increased fork oil viscosity that i would find more fork flex... and might need the brace.

i installed the brace first and rode with it for just under 1000 miles before changing the fork oil, fork springs, and rear shocks to improve ride quality. during that time, there was no perceptible difference.

Yep I noticed the same thing exactly.
When we start a turn our counter steer Input pushes the front tire to
the outside and the bike falls into the lean.

A little twist slop In the forks would cause an easier turn In once the bike
starts to lean.
The added stability In and through the turn Is well worth a little extra
Initial bar pressure.
Remember, you can use less bar pressure If you Learn to trail brake

Trailing off the front brake keeps the front forks compressed a bit longer
there by decreasing effective rake and that quickens the steering.

Each bike and rider are vastly different.
The Superbrace was Night and day on my Roadster wich would probably
have more fork flex than the Iron due to more fork travel.

I hear ya
I'll say It again,
Tar line or crack tracking with my stock 19" dunlop front was reduced
more by taking front tire pressure to 33.5 psi.
Say It was 50% better with an extra 3.5 psi
Setting proper rider sag took another 25% of the wiggles out.
The Brace sealed the deal.

I can still Induce a wobble over the cracks by stiff arming or Gorilla
gripping the bars.

If some odd road thing happens and starts a wobble I power out of It.
Unloading the front just feels right.

Also If I snap push the bar at big speed to start a wobble It stops very quickly.
Yeah I'm a little nuts but I hate wobbles and there Is no reason a sportster should do this.

Cool Speed Tested to 103 or was It 104,

I don't like lookin down at big speed so lets cal It 100+ mph

If I had a Sportster or any other bike that I could not tune to
be Rock stable and on rails past 100 mph,

If I did everything possible and still had a wobble I would sell the bike
and never look back

The way I have my Sportster handling Is almost perfect..
Once there I can't wait to try a better set of tires.

Dunlop GT501's
ME 880's
Avon Venom's

Narrowed It down to these three..
