i ride dunes a lot, but i also ride in the mountains on some rough trail, and rocks.
i kinda want the irs but i dont know how they'll do in the sand, and jumping. o and do the outlaws have carbs or fi?

 

They use KTM's carbureted engines.

The 525 IRS is an awsesome sand quad but where it shines is in the rough stuff, like rutted and rocky trails.
It placed a close second in a shoot out including the KTM 525 and the Outlaw 525 sra

 

Sand is great on my Outlaw. Too throw it sideways take a little different rider input. To break the rear end lose you have too move forward and inside a little to unload the IRS. Jumps great off camber landings no problem.

 

I have to agree with Jimmy the rough stuff this things rides like a Cadi!! I can really tell the difference when i ride our solid axle KFX 450R then take mine down the same trail and man is the clearance difference HUGE no complaints I love the IRS OUTLAW!
