Bought a new 2015 left over Z Force 800 in May of this year. New to the UTV world, but did have a Polaris Sportsman for 8 years before buying the Z Force. So far I have just over 100 miles on it and am very pleased.
Already swapped the airfiter for a unifilter. Added an LED lightbar to the roof and the radio I previously had on my Polaris. I also installed 2 - 3/4" red LED lights under the center ignition console to light up the inside floor/cup holder area. Had a 60" plow installed at the dealer along with a full windshield that I found will be better sitting in the until winter rather then mounted.
Purchased from Karns Performance in Mechanicsburg, PA and they were great to deal with. They are about 2 hours from me, but great customer service is worth a drive from anywhere.
