600 RMK® 144



The 600 RMK 144 is a great 50/50 crossover snowmobile. It is for riders that want deep snow maneuverability with Rider-Balanced™ on-trail confidence.

Rider Balanced Control
  • Rider-Balanced AXYS® Chassis: The AXYS chassis for the 144 platform is light and strong, offering rider balanced characteristics critical for the 50/50 rider. The rider is moved into a balanced position on the sled so it rides flat through the corners. When the trail gets rough or the rider jumps off into the powder, rider balance enables the rider to move back and make the front end light to climb up on top of the snow or the moguls.
  • IGX 144 Rear Suspension: A core element to the AXYS 144 platform is the IGX 144 uncoupled rear suspension, which offers the ultimate blend of durability and strength. The IGX 144 rear suspension provides RMK-inspired off-trail agility and balance with a drastically improved on-trail ride. Pitch is controlled through geometry in this rear suspension. And with 43% more front torque arm travel, this sled features reduced bottoming and less drag off-trail. An optimized, lighter, tipped rail beam design gives the sled a nimble feel.
  • PowderTrac™ Hybrid Running Boards: The PowderTrac Hybrid running boards offer optimized design with 56% open space for maximum snow clean out while maintaining extreme strength. Designed to serve the needs of riders on- & off-trail; Efficient design delivers maximum strength & snow clean-out with 56% open space; Front is wide & flat for foot comfort & stability; rear has tapered, dual-angle design for mobility & snow clearance
Unrivaled Acceleration
  • Lightweight: At 455 lbs, the 600 RMK 144 on the AXYS 144 platform is lightweight yet strong. It allows you to get up on top of deep snow faster and offers quick acceleration.
  • 600 Cleanfire® Engine: This liquid-cooled Cleanfire® engine with semi-direct injection (SDI) delivers outstanding throttle response and instant acceleration. These powerful, efficient engines start easily and reliably and they calibrate automatically as the temperature and elevation change. These engines deliver impressive fuel economy in real-world riding situations, which, for Polaris riders, means aggressive, up-tempo riding, not low-rev lab conditions. In the AXYS® chassis, the 600 engine features lightweight integrated mounts, electronic oil pump and bypass thermostat.
Rider Centric Comfort
  • MessageCenter Gauge: Informative and easy to read, this instrumentation keeps a rider aware of sled operating conditions and provides a wealth of additional data. Easily viewable LCD screen, 4.3" diagonal measurement; Scrolling message center keeps rider informed; Increased number of tell tales by over 60%; Large buttons can be operated with gloved hands; Brightly lit display is easily readable in all light conditions
  • LED Lights: All models built on the AXYS® platform feature standard LED headlights. LED headlights deliver the industry's best lighting: Nearly 1 lb. lighter and high beams are 80% brighter than incandescent lighting; Color temperature or output of the lights (the “whiteness" of light, reported in Kelvin) is 5000K, closely matching daylight; LED headlights last the entire lifetime of the sled. A major durability enhancement over traditional incandescent headlights which experience filament burn out; For constant visibility and enhanced safety, the low beams remain on at all times. Even when the high beam is activated, there is never a period of no light.
  • Left-Hand Controls: The left-hand controls feature improved ergonomics, updated styling, and enhanced hand and thumb warmer control. The controls are easy to operate with gloves on, and have an improved tactile feel.
  • Standard AXYS 144" Underseat Bag: Provides 1024 cubic inches of secure storage space; Weather-tight design seals out snow; Storage can be accessed through zippered and velcro enclosure that is covered by additional material and buckle down straps; Bag is attached and located underneath the seat and tank and atop the tunnel; Combination of semi-rigid, compression-molded materials and polyester
  • 2.0 Series 4 Track: Stiff lug base for hard-pack performance, soft and flexible tips for superior deep snow traction.
  • RydeFX® MPV Shocks: RydeFX® shocks provide a great foundation for ride and handling.
