I know alot on here would tell you to get the AC just because of brand loyalty.
I will tell you that if AC offered a power steering system then I would go with the AC but they don't. IMO the next ATV I buy WILL have power steering. When we ride it's nothing uncommon for us to do 60-100 miles in a day. (and it's all fairly rough riding) I think(hope) that power steering is going to eventually be comon on most ATV brands.

 

Junk man
I am not a brand loyalist.
I have both cat and Yamaha. they both have pros and cons.
I do wish cat had power steering, not its not needed.
