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 by providing the best ride for the chosen mode, using a semi-active suspension system that electronically adjusts all four shocks based on various inputs from the IMU and other sensors.
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, including its movement, velocity, pitch, roll, and acceleration. It takes this information and reacts accordingly to control the electronic shocks, ensuring optimal performance for the riding conditions.
What are the three active events that the Dynamics system is designed to manage?
-The three active events are acceleration/deceleration, braking, and cornering. The system adjusts the compression and balance of the shocks to provide the best performance during these events, ensuring a smooth and controlled ride.
How does the front track shock contribute to the overall performance of the Dynamics system?
-The front track shock is unique as it controls the balance of the vehicle forward and back. It allows the rider to have more ski pressure and bite when leaning forward and a lighter touch when leaning back, thus enhancing the vehicle's maneuverability and control.
What are the three rider-selectable modes available in the Dynamics system?
-The three rider-selectable 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 adaptability, and Extreme mode is for high-performance riding over rough terrains and jumps.
How does the Dynamics system adjust to different speeds while riding?
-The Dynamics system is speed-sensitive, meaning it will naturally adjust the compression level of the shocks based on the speed the rider is going. For instance, if in Comfort mode, the system will ramp up compression as the speed increases to maintain the desired comfort level.
What additional features are available on the 7s display for the Dynamics system?
-The 7s display has a dedicated Dynamic screen that shows real-time information while riding. It displays throttle and brake input, speed, and an accelerometer representation from the IMU. It also shows the target shock position and compression setting for all four shocks.
How does the Dynamics system ensure a smooth landing when the snowmobile goes airborne?
-The IMU detects when the snowmobile has less than one g of force, indicating it's airborne. The system then stiffens the compression to prevent bottoming out on landing, ensuring a smooth ride and maintaining momentum.
What is the significance of the Fox Live Valve 2.0 compression shocks used in the Dynamics system?
-The Fox Live Valve 2.0 compression shocks are top-of-the-line electronic suspension technology. They allow for continuous adjustment of the compression, providing the best ride for the chosen mode and enabling the Dynamics system to react quickly and efficiently to changing riding conditions.
How does the Dynamics system manage different riding scenarios such as high-speed corners and rough trails?
-The Dynamics system is designed to balance all active events perfectly, whether it's high-speed corners, tight twisties, or rough trails. It adjusts the shocks to maintain ski pressure for turning, bump compliance, and balance between ski and rearward traction, ensuring a smooth and controlled ride in all scenarios.
