You probably did already, but check your wheel bearings...to be safe. I have had two wheel bearing failures, second at 65 mph, twelve hundred bucks damage...
Whole new set of quality aftermarket are less than fifty bucks...
Hope you find it...

A fork brace did it for me. The Wobble was gone.

I actually had a wheel bearing failure last year when I PC'd the rims. I replaced the bearings front and rear specifically to prevent such an issue, and guess what? I'm out joy riding along and I start hearing this god awful noise from the front end. The seal let go and blew the grease all over my front end.

This also occurred to me. I will definitely look into this.

If you lower the pressure a bit, you should be able to get to a greater speed before encountering the wobble.

I run mine 30/40 ...

As soon as the rain here stops, I'll give this a try.

I've looked into this, but I can't seem to find one for the inverted front end I have on the bike.


Thanks for chiming in here guys, your responses are greatly appreciated.

I have 14" apes and I pretty much ride slammed. It had no effect on how my bike handles. I agree, I would start looking at my rims and tires.

Got the Carlini drag bars all installed this weekend. Took a test ride at 100 down the highway, no more wobble...

This may be a stupid question...but I didn't see it asked. Are those inverted forks over length or is there any added rake to the triple trees? Trail issues could be causing it to shopping cart at speed.

PM sent.


These new bars really did the trick. No more wobble; sometimes I'm at 85mph and don't even know it. The bike handles a lot better, feels like I'm on a rail cruising down the highway.
