    -The three rider-selectable modes are Comfort, Rally, and Extreme. Each mode offers a different level of shock compression and performance tailored to the rider's preference and trail conditions.

  • How does the Dynamics system adjust to different speeds while riding?

    -The Dynamics system is speed-sensitive, meaning it will naturally ramp up the compression of the shocks if the rider goes faster, and soften the shocks if the rider goes slower, adapting to the speed and maintaining the desired level of comfort or performance.

  • What additional features does the 7s display offer for riders using the Dynamics suspension system?

    -The 7s display provides a dedicated Dynamic screen that shows real-time information such as throttle and brake input, speed, and an accelerometer representation from the IMU, along with the target shock positions and compression settings 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 (is unweighted relative to normal gravity) and adjusts the compression to stiffen the shocks, providing bottom out resistance and maintaining momentum upon landing.

  • What benefits does the Dynamics suspension system offer to riders?

    -The Dynamics system offers a smooth and comfortable ride with adjustable modes, excellent cornering with nearly perfect flat turns, confidence and compliance over rough terrain, improved control during acceleration and braking, and optimal performance during airborne events to prevent bottoming out.
