Both are available with the 850 Patriot, Patriot 9R and Patriot Boost engine packages with either 155 or 165 length tracks in the 2.75 Series 8 or 3.25 Series 9 versions. The RMK Khaos also features a 146-inch track in the 2.6 Series 6 or 2.0 Crossover versions, but it’s not available with the Patriot Boost engine.

Both are built on the sleek Matryx RMK platform with narrow bodywork designed for agility in extreme terrain. Both have the new Polaris throttle system, new running boards, 1-inch lower seat and a lightweight headlight designed specifically for deep snow riding conditions.

With snowmobiles, there’s still the perception that to upgrade from a 600 to an 850 or even a turbo really isn’t that great of a jump. After all, you’re already spending several thousand dollars for your snowmobile. What’s a couple more bucks for the “biggest and baddest” on the mountain?

At first glance, you don’t see a lot of difference between the two. Both are based on the lightweight Radien2 platform with a short tunnel and extruded running board design to allow them to glide through deep powder with minimal drag.

The new design eliminates this possibility by creating a totally sealed cable cover. This allows a new coated cable to slide more easily through the cover while basically squeegeeing the snow and water off the exposed cable and keeping this unwanted moisture outside the cable cover.
