Never had a Polaris......been around some on trails....
All comes down to features...pricing....warranty.....reputation....promotions
Razr's are popular around my parts...I've have had Honda..Yamaha and now a Kawasaki...
Kawasaki Teryx comes with a 3 year bumper to bumper warranty..unlike the other mfg's 6 months
In spring of '18 they offered $2K off MSRP....that's when I bought mine..its been trouble free at 3500 miles
Utah has miles & miles of public land/trails to ride....when you're 40+ miles from the truck....
You need a reliable machine to get ya back.....
