While I hear what you're saying I just don't see the top racers using anything like this for the 700xx.
Also, when you say "corr truck", which of the 5 truck divisions are you talking about? All kinds of racing uses sway bars, CORR rules state that you can remove sway bars from the buggies (page 96) so I believe that your argument has merit but lacks in specifics to this machine.
I believe that while this would\could be important for flat and MX tracks but I doubt that the majority of the owners of IRS machines who don't race MX or flat track would want a stiffer, more SRA feel to their quads. I may be wrong, I've asked some of the Outlaw IRS guys the same question as more of them race their quads presently.
As always, I will be forthcoming with any and all feedback.
As a final note, please don't take this and my other responses as me bashing you or your products, but rather a healthy debate on what's best. That's what a forum's all about right?
I don't take what you say as criticisms and if you take a look at my Tech FAQ section of my website you will see that I'm always eager to express my thoughts and research with others. It sounds like you have some good knowledge of independent suspension. This is probably why you purchased the XX in the first place. You no longer have to wear a kidney belt and the ride is extremely smooth.
I too love independent suspension. I have spent a great deal of time in the last 6 years researching, developing, and testing IRS on ATV's. If you look through the products I offer you can see that I am not all about the $$$. I am one for technology and I want to bring it to the ATV industry because I love ATV's. Of course, i also need to be a business man or I wouldn't be in business.
Racers for the most part are constrained to the components provided to them from the manufacturers. Durablue and Rath don't make anti roll bars that are rated for extreme travel and the kind of abuse that desert racing, motox, and cross country produce. These racers have had only a few months to try to get the most out of their machine. We have spent years developing IRS. You could say maybe we don't know how to make a machine handle as well as the desert race team did. But I can assure they can't produce tire deflection to the magnitude in the picture below. The only way we are able to achieve this type of traction was with Anti Roll bars all around and the same roll stiffness in this picture is used in Cross country racing.

Our first IRS kit was sold to Honda R&D in California before anyone heard of the 700xx existing. My first IRS system without sway bars was better then the Honda engineers were able to come up with in 7 years of development with a lot more man power then I have. We did our testing out in Ohio with a pro rider that rides for the Honda. Every time we went out there several Japaneses guys just happened to be out for the ride. I'm a modest person and I'm not trying to brag I'm just trying to get everyone away from the common idea (if Honda didn't do it then it can't be any good).
If Honda hasn't figured out their roll stability problem already then it comes down to simply a design issue. A sway bar can only twist to a given degree before the spring member fatigues and falls to permanent set. Its simple math. If A 13" torsion member can twist a total of 15deg then a 26" torsion bar can twist 30deg. Our patent pending design allows you to use a long bar and connect the linkage closer to pivot of the a-arm. There fore you won't fatigue our bar made from 4130 chrome molly yet we can yield a greater roll resistance.
Honda and Polaris are magnitudes off with their roll rates! We have proven this with one of their test engineers and you can bet you will see 2013 Honda xx with a front and rear sway bar much stiffer then the current design. Their problem is how to make a bar that can handle the abuse but utilizes a stiffer roll rate. If you doubled the diameter of the current XX anti roll bar it would break! If they make their bar longer then it has to mount out farther on the a-arm requiring a larger twist angle. Second problem is mas production. you can be sure production limitations have a lot to do with it. they won't mas produce a anti roll system that utilizes many pieces and costs much more then the common design. I have tried many different designs before our current one and this one works very well.
In one month our first production run will be complete. At this point if the top racers don't have upgraded sway bars they won't be top racers any more.
We have been able to create extremely competitive IRS ATV's and the revolution has already started. We hare honing our setups and our numbers are impressive. Unfortunately IRS is extremely expensive to do right and I believe our main market will be upgrades for the IRS vehicles made by the big manufacturers. People are very resistant to extreme change, but look at the following the 700xx has already created.
As far as they type of CORR vehicle we are talking Pro2 and 4, also super buggy. The sway bar removal is allowed but not practical for the high speed high performance classes. For these vehicles a rear sway bar is more important then a front. These vehicles with a wide track width to center of gravity height ratio. also the cg on these vehicles are much closer to the suspension's roll center making the force fulcrum much shorter when compared to an ATV. We are at an extreme Body roll disadvantage with ATV's.
