I have a Kodiak 450 with a diff lock and think it is a very good
set up, and mine can be in 4wd going DOWNHILL, thats one thing Polaris cant say.
100% BS where do you get this false information????? polaris can go downhill in 4WD do a little more research.
i know the kodiak 400 doesnt have a lock in the front but it is still "considered" to be 4WD b/c it says 4WD on the side of the 4wheeler. so yamaha obviously believes that it is a 4wheeldrive wheeler. so 4 u to try and tell me that is isnt a 4wheeldrive 4wheeler is more BS since yamaha Specifically states on the side of the wheeler 4WD.
