I don't know of any ATVs other than Polaris that put power to the front wheel that can make use of traction the most. The others just send power to the front and whatever spins the easiest spins first. Of course on some models you can pull push another button, switch another switch, pull another lever to get some kind of "locker effect on the front.
With Polaris you just thumb the switch. 2WD or AWD.
And Polaris' low gear can't be described. It has to be
experienced. The Polaris auto descent control is sweet in either high or low. It will actually bring you to a stop if you wish on downhills without touchng a brake.
