Q & A
What is the main focus of the new Dynamics suspension system introduced in the 2025 Polaris Snowmobiles?
-The main focus of the new Dynamics suspension system is to enhance trail performance. It is designed to provide the best ride for the rider by adjusting all four shocks electronically based on the trail conditions and the rider's chosen mode.
How does the Inertial Measurement Unit (IMU) contribute to the Dynamics suspension system?
-The IMU is at the core of the Dynamics system. It measures the inertia of the vehicle, constantly monitoring its movements, velocity, pitch, roll, and acceleration. This information is used to electronically control the four shocks, ensuring optimal performance for the chosen riding mode.
What are the three active events that the Dynamics system is always looking for?
-The three active events are acceleration/deceleration, braking, and cornering. The system adjusts the shock settings to provide the best balance and control during these events, ensuring a smooth and efficient ride.
What makes the front track shock unique in the Dynamics system?
-The front track shock is unique because it is the only semi-active suspension system on snow that controls all four shocks. It plays a crucial role in controlling the balance of the vehicle forward and back, allowing for better ski pressure and rearward traction.
How does the Dynamics system react during an Airborne event?
-During an Airborne event, the Dynamics system stiffens up the compression to prevent bottoming out upon landing. It uses the IMU to detect when the snowmobile has less than one g of force, indicating that it is unweighted relative to gravity, and adjusts accordingly.
The three modes are Comfort, Rally, and Extreme. Comfort mode offers the softest ride for easy trail riding, Rally mode is for spirited trail riding with a wide range of settings, and Extreme mode is for high-speed riding and rough trails, offering the stiffest suspension settings.

How does the Dynamics system adjust to different speeds while riding?
-The Dynamics system is speed-sensitive. It starts with a baseline compression level for each mode but will naturally ramp up the compression as the speed increases to maintain the desired comfort and control levels.
What additional information does the dedicated Dynamic screen on the 7s display show while riding?
-The dedicated Dynamic screen shows real-time information such as throttle and brake input, speed, and an accelerometer representation from the IMU. It also displays the target shock position and compression settings for all four shocks.
How does the Dynamics system enhance the overall riding experience on the trail?
-The Dynamics system enhances the riding experience by providing a soft and compliant ride in Comfort mode, nearly perfect flat cornering in every corner, and increased confidence under acceleration and braking. It adapts to various trail conditions and riding styles, offering a complete next-generation level of trail performance.
Is the Dynamics suspension system available on all Polaris Snowmobiles or just the INDY VR1?
-The Dynamics suspension system is exclusively available on the INDY VR1 snowmobiles, enhancing their trail performance and offering a superior riding experience.

🚜 Introduction to the Dynamics Suspension System
The paragraph introduces the Dynamics Polaris, an advanced suspension system designed for the 2025 model of the indd VR1 snowmobile. It highlights the system's ability to redefine trail performance by utilizing a semi-active suspension with four electronically controlled shocks, managed by an Inertial Measurement Unit (IMU). The IMU measures the vehicle's inertia, velocity, pitch, roll, and acceleration to adjust the shocks in real-time for optimal performance. The introduction emphasizes the system's innovation and its focus on delivering the best riding experience tailored to the rider's chosen mode.
🏍 How the Dynamics Suspension System Works
This paragraph delves into the mechanics of the Dynamics suspension system, explaining how the IMU serves as the 'brain' of the system, processing data from acceleration and deceleration inputs to control the four Fox Live Valve .0 shocks on the sled. It covers the unique feature of controlling all four shocks, including the front track shock, which influences the vehicle's balance. The paragraph also discusses the system's responsiveness to active events such as acceleration, braking, and cornering, and how it adjusts the shocks to maintain balance, traction, and control during these events. The explanation includes the concept of Airborne detection and how the system prevents bottoming out during jumps or unweighted moments.
🏁 Rider-Selectable Modes and the 7s Display
The final paragraph discusses the three rider-selectable modes within the Dynamics system: Comfort, Rally, and Extreme. Each mode offers a different level of shock compression, catering to various riding styles and conditions. The paragraph explains how these modes are speed-sensitive, automatically adjusting the compression level based on the sled's speed to maintain the desired comfort and performance. Additionally, it introduces the 7s display that comes with every Dynamics-equipped Indie VR1, which provides real-time data on throttle and brake inputs, speed, IMU accelerometer readings, and shock positions, enhancing the rider's interaction with the system and their understanding of its operation.
