400 HO Outlander
500 HO Sportsman
500i AC

Out of these 3, what is the best riding machine, for all day all types of terrain, basically which will keep your back from being damaged after a long ride, I know the Polaris is renowned for its ride, but now that the other 2 are in the game, do they compare or are they better in ride quality.

Has anyone ridden all 3 as this is the best way to find out!
Thanks

 

id say the Sp

my friend owns an outlander, seems really tippy has rolled it 4 times, and my 500 still rides smoother.

 

dont know about the other 2 but my ac 500i is a really smooth ride and stable as well, we go on some pretty steep inclines with 2 ppl per machine and have never tipped or even felt like it was going to go over

 

Been on a Sportsman, own a Cat 500i. The Sportsman probably rides a little bit smoother, but only a bit.

The big difference was in going from a live axle (Big Bear) to IRS (Cat 500i). Like going from a truck to a Cadillac.

 

I've drive your choices and I have to go with the sp as well. Polaris make heavy atv's but man they are smooth.
