New PRO-RMK® React™ Front Suspension
Polaris® RMK® models are the world’s greatest mountain sleds. They are the lightest, strongest, and most flickable deep snow snowmobiles available, and for model year 2019, these sleds have been elevated to the next level of performance with the all-new AXYS® PRO-RMK® React™ Front Suspension, new PowderTrac™ XT Running Boards, new lightweight components, and are available with the most powerful Polaris® snowmobile engine ever, the all-new, SnowCheck-exclusive, Polaris® 850 Patriot™ Engine.
The all-new AXYS® PRO-RMK® React™ Front Suspension provides riders with the most precise and effortless deep snow handling. A rider can effortlessly initiate and hold sidehills and experience less fatigue with the most predictable mountain sleds available. The new front suspension features all-new geometry and an adjustable 36”-38” ski stance. All-new forged spindles and forged control arms that are optimized for strength and durability. Available only on 850 PRO-RMK® models are all-new, lighter-than-titanium SLS shock springs that feature a patent-protected, proprietary technology that makes the steel springs durable yet very light.
The all-new PowderTrac™ XT Running Boards feature new geometry at the back of the running boards for improved sidehilling clearance and deep snow capabilities. The new design lets a rider lean farther in deep snow or on a sidehill while maintaining traction. These new running boards are exclusively available on the MY19 850 PRO-RMK® 155 and 163 models.
