A quick google turns up..

Just keep in mind that the Twinwalls are significantly stronger and stiffer by nature than a regular Fatbar and Protaper 1 1/8 bar. The crossbar will make them even stiffer which transmits more harshness and vibration to your hands and arms. The Twinwall bar is the ONLY bar I know of where it is ok to remove the crossbar.

and..

Yes, you can actually remove the crossbrace from the Twinwalls. If you do, you will be left with a handlebar that is equally as strong as a fatbar or pro-taper, yet has a longer fatigue life than either of them.

With the crossbrace attached, the twinwall is the strongest safest bar available. Without the crossbrace, you are giving up a LOT of strength, yet end up with a bar that is equal in strength and flex to a fatbar or protaper handlebar.

Simmo737 has removed the cross brace from his for some time now. I removed mine recently also.

20 hrs on Flexxbars, I can never ride with conventional bars again.

I've sent an email to Renthal re the structural integrity of the twinwalls with the crossbrace removed. Will hopefully hear back some time next week.

Yep! I absolutely agree!

I'm planning on going with the Twisted Engineering CarbonFiber Composite bars. I'll need to figure out an underbar mount for the Scotts.

I'm considering those bars as well. Is there any comparison on how the different versions flex compared to FLEXX bars?

Make sure that's what you want. Your bars may be too high up with the under bar mount.

Truly. I won't know until I get the 2013 bike and sit on it. For the 2005, I could use a half-inch to 3/4" higher. No more, tho.

As for the flex vs. the Flexx, both the folks at Flexx and Twisted respond within a day or two to e-mailed questions on their web sites.

The Flexx folks have very strong and detailed opinions about their product's characeristics and options based on your bike/rider/speed descriptions.

I haven't asked Twisted as detailed a series of questions yet, but I suspect that group of whacky dirt-biking engineers know which way is up.

BTW, there is a Twisted thread here and over at the ThumperTalk in the Engineering forum (or whatever it is called).

IMHO the Flexx bars are worth every penny. They are bulky and heavy but for me they make riding more enjoyable because of the comfort and reduced hand pain/fatigue. They were the first thing I bolted onto my gasser. I will not ride in the dirt without them.

Bulky yes. Heavy? Not much more at all, just look that way.
