They both have thier advantages, the scrambler's got the automatic and the reverse and the 4x4, the DS650 has the power and the speed and I prefer the way the DS rides and handles. I own both and it really just depends on who I'm riding with which one I'll take, If I ride with my beer drinkin' utility ridin' buddies, I'll take the scrammy...if I'm riding with sport quads...I take the DS....nothin' like a good uphill drag race in the sand with a ground poundin' modded bomber!
