I have read in this forum about all of the body roll of the 1k. I bought mine over a year ago in Utah and put 2500 miles on it in Moab. Still have the original belt and no issues except how stiff it is. My son has a 1k and several friends and they all are much softer. I took 1 inch out of the adjustment and that helped some. Its still much stiffer than all of them and zero body roll. everything is stock , don’t know what it is, maybe wrong springs. Hard to tell without testing them. Anyone else have this problem?
