Here's another look at one of the latest, greatest 4-wheeled machines on the market. Quad riders have been stuck in a conundrum of how to get a trail machine with the performance capabilities of modern moto sport-quads. This is Polaris' solution. Read the report.

Man JC - I am glad you guys wrote this test! I actually rode this same bike and it is one of the best ATVs I have ever ridden.

I'm a big fan of the Outlaw considering its KTM mill, hydro-clutch, and Fox suspension but would want a straight axle model. No IRS for me, thanks.  But good report gents.

Agreed, I'll take the straight axle. One of the problems I had read in earlier tests was the IRS simply working too good, which hindered the rider's ability to pitch it in turns.

After riding this thing around Oregon with a few straight axle quads, YFZ450, TXR450 and so on...I am compelled to share the gospel truth about IRS with you folks. First of all, the way the IRS soaks up the terrain is simply amazing. When switching back-and-forth on the other quads the IRS really shined. It absorbs bumps, rocks and ruts so much better than the fixed axle that it made everything easier. Hill climbs, hauling ass through rough stuff it is great. It reminds me of the difference between a dual shock MXer and a mono-shock equipped bike. The technology is not what we're used to and for some folks, that makes it difficult to embrace/accept. The problem is that although its better in some aspects - it feels so different than what we are used to. Thats where the test riders in the report Hog Wild is referring to must have come to the belief that it makes it more difficult to turn. That's not entirely true though. In regards rto sliding, flat-tracking through a turn like we are all used to doing on a fixed axle ATV - well, it not as mindlessly easy to do on the IRS. You can still slide the rear but you have to hang off the inside more and take care to unweight the outside wheels in an effort to counter the outside suspension compressing. On the flip-side, in the technical stuff it feels much more precise and manueverable than a fixed axle. The suspension working seems to act as a sort of articulation (Think Monster truck steering) which helps it steer quicker. This is the heart of the 'problem' with the IRS - it takes a bit of getting used to but after that it opens up another level to ATV riding as I see it. Overall the reduced impact on the rider and the added control in the really difficult terrain make an IRS quad like the Outlaw simply easier to ride - but I will not deny - it is different. Many of us have been abused off-road anre have nagging injuries bugging us more and more as we get older. The IRS reduces the amount of impact transferred to the rider and that will make this layout popular among the more seasoned off-road riders in the future you mark my words baby. The fixed axle Outlaw looks liek a bad-ass though. Our local Polaris dealer has a few and they look cool but at this point I am a believer in IRS.

Having had a number of Jeeps from the 86 CJ on I found much of what you are saying to be true when Jeep switch from a straight front drive as rock crawling and such became much easier. After reading the original tests on the Outlaw I felt certain that much like the difference we found in wheeling, here too would be those differences and once we learned to use them to our advantage things would become easier and they did. Independence of all 4 wheels will take time to understand but once that understanding is complete, the advantages will make a world of difference in your ride and where you can go or what you can do with the machine.

Lucky you, Blender/Hogwild. Polaris does offer the Outlaw with a straight axle - the 525 S. But, for my two cents, I'd take the IRS too...

IRS is totally superior in performance. Itsy bitsy item of tire hook-up, the IRS wheel is lighter and moves quicker, to stay down. Solid axles are subjected to tremendous forces that want to bend that axle. IRS has no problem there.

IRS can have lower center of gravity. Anyone want to see IRS in action? look at World class Rally racing, see Subaru, See Subaru Run, See Subaru Fly. :-)

HW - That is exactly the stage that IRS ATVs are in at this time. The technology is making them much more rider friendly but a bit of short-sighted writing might have helped keep the IRS stuff down in the early going. The rock crawler analogy is perfect in a few ways. First of all this ATV goes where I thought only a FWD would go more than a few times. Also then the way it handles is going to be an advantage in more situations than it is a disadvantage - at least that is the way I see it at this stage. As far as the CG goes - I know it applies wel to cars but I am not sure how it plays out exactly in the ATV world. The ATV sits taller than say a YFZ 450 when you see them side-by-side.

Rockcrawlers have straight axles.  Desert pre-runners have IFS.  There is a reason rockcrawlers have straight axles and a reason pre-runners have IFS.  They are mutually exclusive.
