Take on the terrain with confidence as you glide over bumps and dips thanks to the independent A-Arm front suspension and PRO-CC rear suspension. With adjustable gas IFP shocks on all corners, you can fine-tune your ride to suit your preferences and conquer any obstacle with ease.



The RipSaw II track with a length of 137 inches and a width of 15 inches provides exceptional grip and flotation in deep snow, while the carbide skags ensure precise handling and cornering. Whether you're blazing down straightaways or navigating tight turns, this snowmobile is up to the task.



Spend all day on the trails without worrying about running out of fuel, thanks to the generous 11.5-gallon fuel tank. The LED headlights illuminate your path, while the tinted windshield adds a touch of style and reduces glare for improved visibility in varying light conditions.



Settle into the comfortable vinyl seat, complete with heated hand grips for added warmth on chilly days. The driver-focused design puts you in control, with all the essential gauges and controls within easy reach. With a refined mid-height seating position, you'll feel confident and in command as you tackle the terrain.
