Additional Features

• PRO-LITE SEAT: Mountain snowmobiling requires a different seat design and that is what Polaris delivers. The PRO-Lite seat is shorter to allow you to easily swing a leg over from one side of the snowmobile to the other.
• LED LIGHTS: All models built on the AXYS platform feature standard LED headlights to deliver the industry's best lighting that is 80% brighter than incandescent lighting.
• MESSAGECENTER GAUGE: Informative and easy to read, this gauge keeps a rider aware of sled operating conditions and provides a wealth of additional data.
• 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 once-piece, stylized design, the mountain hoop is made of durable polyurethane material.
