The belt primary drive system ensures efficient power transfer from the engine to the track, keeping you in control at all times.



With a sleek aluminum frame and durable plastic body, the 2025 Polaris 850 RMK® KHAOS® 155 is built to withstand the rigors of mountain riding. The MATRYX frame design provides unmatched strength and stability, while the skid-resistant floorboard and gripper® skis ensure superior grip and control in all conditions.



On the suspension front, this snowmobile features an independent A-arm front suspension with RMK® React™ technology, delivering a smooth and controlled ride over bumps and rough terrain. The Walker Evans Racing (WER®) shock absorbers with shock-mounted adjustments allow you to fine-tune your ride to suit your preferences.



When it comes to stopping power, the RMK® branded hydraulic disc brake at the rear ensures reliable and consistent braking performance, giving you the confidence to tackle steep descents and navigate tight corners with ease. The adjustable gas shocks with remote reservoirs provide unmatched damping control, keeping you comfortable and in control throughout your ride.



The sleek one-piece vinyl seat offers comfort and support for long days on the snow, while the temperature warning light and fuel gauge make it easy to stay informed about your snowmobile's status. With LED headlights and a tinted windshield, you'll have clear visibility in all conditions, while the heated hand grips provide extra comfort on chilly days.



With its Series 8 track measuring 155 inches in length and 15 inches in width, this snowmobile offers exceptional traction and floatation in deep snow, thanks to the 2.75-inch lug height.
