Steering and Suspensions PRO-RIDE PROGRESSIVE SUSPENSION OPERATION
Operation
The Pro-Ride progressive suspension allows the rider to easily adjust the desired amount of weight transfer, ski pressure, and ride comfort using the following components: Rear track shock spring preload Rear track shock compression dampener Front track shock spring preload Front track shock compression dampener IFS shock compression dampeners IFS shock spring preload Unlike other Polaris rear suspensions, the Pro-Ride progressive rear suspension is not coupled and does not feature front or rear-rear scissor stopsThe front torque arm is not linked with the rear crank or rear scissorWeight transfer during acceleration is controlled by two primary factorsThe first weight transfer control is the rear track shock spring preloadThe second weight transfer control is rider position Increasing rear track shock spring preload reduces weight transfer during acceleration and increases ski pressure in all driving modes Sitting or standing close to the fuel tank decreases weight transfer and increases ski pressure in all driving modes Decreasing rear track shock spring preload increases weight transfer during acceleration and decreases ski pressure in all driving modes Sitting or standing at the rear of the seat increases weight transfer under acceleration and decreases ski pressure in all driving modes Ride comfort is controlled by the compression dampener adjusters on the IFS, and frontrear track shocksAll shocks offer sixteen compression dampening settings Increasing shock dampening reduces bottoming, but makes the ride stiffer Decreasing shock dampening makes the ride softer, but increases the chance the suspension will bottom-out
