A performance upgrade designed for the Polaris Sportsman 570 all-terrain vehicle (ATV), this component modifies the vehicle’s transmission system. It typically includes elements such as new weights, springs, and possibly a helix for the driven clutch. This collection of parts is intended to optimize power delivery to the wheels in various riding conditions.
The implementation of this modification enhances the ATV’s responsiveness, improves acceleration, and adjusts the engine’s RPM range for optimal performance. This can result in improved low-end torque for navigating challenging terrains, better mid-range power for trail riding, or increased top-end speed, depending on the specific configuration of the kit. These improvements are particularly beneficial for riders who frequently encounter varying elevations, haul heavy loads, or use larger-than-stock tires.
