Lightweight

Lightweight

Polaris snowmobiles are the lightest sleds on the mountain. Polaris®mountain sleds have always been light AND rigid with added strength & durability while reducing weight on the RMK® AXYS® platform. Polaris uses design optimization software to analyze the loads and stress points for various systems and components of the snowmobile which allows the team to design lightweight yet durable snowmobiles. Providing riders with instantaneous lift, Polaris sleds help riders get up on top of the snow faster.

ALL-NEW SLS Shock Springs

Additional Features

XT Hyfax

XT Hyfax

New profile design optimized for lighter weight while maintaining durability.

PRO-Lite Seat

PRO-Lite Seat

Mountain snowmobiling requires a different seat design and that is what Polaris delivers. The seat is shorter to allow you to easily swing a leg and hop over from one side of the snowmobile to the other.

LED Lights

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.

Mountain Hoop

Mountain Hoop

Re-designed in 2016, the mountain hoop is more ergonomic and has been moved down 2.5" to prevent hitting the rider in the chest when in steeper terrain. Now a one-piece stylized design, the mountain hoop is made of a durable polyurethane material.

Brakes

Brakes

These lightweight brakes feature a fixed 2 piston opposed caliper design for an improved and quicker braking response and feel. The brake pad material features higher thermal properties to provide more optimal wear over time.
