Medina, MN óPolaris has introduced the 500 High-Output engine for its Sportsman 500 ATV. The powerplant is a liquid-cooled, 4-valve, 4-stroke Polaris 500 engine with counter balance.
The power is managed by the Dual-Sensing automatic PVT (Polaris Variable Transmission) with the Polaris EBS (Engine Braking System). The PVT requires no shifting and is a dual-sensing transmission that responds to both engine RPM and vehicle torque requirements. EBS utilizes engine compression for braking.
When additional traction is needed, the on-demand 4-wheel drive system is engaged. The system senses when the rear wheels lose traction and start to spin, then automatically engages both front wheels, providing torque to all four wheels. Other systems only engage one wheel, making it 3-wheel, rather than 4-wheel drive.
