What changes did Polaris make to the standard 800 engine to make it the 800s high output? I know that the exhaust header is different on the S's than the earlier 800's, but what else was changed or upgraded?
X 2. I was on a ride this last Saturday and the 2 Rzr S on that ride is what got me interested in the differences as I saw the same out of the S on the hill climbs . I do have a Holz clutch kit on the way and am looking at changing my wheels and stepping up in tire size.I've wondered this as well... I heard the clutching was different too... I have neither, but ride with both and the S seems to be much faster and more powerful on hill climbs...
