right you are rooskey. can-ams visco locking front diff is a very good system but does not engage as quickly as polaris awd system.. To the op, yes, can-ams top of the line rigs have the tri mode power steering which is neat as you can tailor the assist to the way you like it.. I suppose the down side, is that its like high gear vs low gear.. Sometimes you just don't want to have to shift gears.. And by the time you realize you'd like more assist, you're probably already in a situation that requires a death grip on the bars so letting go to press a button is the last thing on your mind.. Polaris has elected to stick with their single mode dynamic power steering system which increases assist at slower speeds and the system all but shuts off around 50km p/hr to give you precise feedback at higher speeds which is what you want.. When going fast you don't want power steering to mask what the wheels are coming into contact with.. It would essentially be lying to you and making the ground feel smoother than it actually is, which is not a good thing at higher speed.. For what its worth, my 2010 850's power steering system will be 4 years old this coming feb and has worked flawlessly since day one.
