Features

Confidence-Inspiring Handling

  • SNOCROSS-INSPIRED COCKPIT: Narrower Cockpit - 4.8” narrower console and 3” narrower at the knees, creates a more mobile rider experience allowing full freedom of movement for effortless control. Maximized Wind Protection & Minimal Drag - Computational Fluid Dynamics (CFD) design tools ensure maximum wind protection and minimal drag for a warmer, more comfortable ride. Sculpted Side Panels - Opens a new dimension of rider mobility allowing the rider to move around the sled rather being confined by it. Wind Protection - Improved leg and lower body comfort and protection. Enhanced windshield design for hand protection and less wind buffeting. Updated geometry for improved aerodynamics.
  • INDUSTRY-LEADING RACE IFS AND PRO-CC SUSPENSION: The Polaris Race IFSdelivers the perfect balance of effort, precision & zero-bump- steer-stability to deliver ultimate handling and control. The PRO-CC Rear Suspension is the next generation rear suspension from Polaris and provides the industry's best acceleration, handling, and consistently smooth ride. The rear skid's coupled design controls pitch through geometry without reducing the fun factor. The front torque arm is calibrated for trail compliance without bottoming.

Corner-to-Corner Performance

  • PROSTAR S4: The ProStar S4 provides easy runability with the spirited performance only a Polaris can deliver.
  • LIGHTWEIGHT CHASSIS: The Matryx platform features a lightweight, rigid chassis delivering superior handling and responsiveness.

Seamless Technology

  • INDUSTRY EXCLUSIVE SMARTWARMERS: Build heat quickly and maintain your customized temperature regardless of the temperature outside. Enhance your ride further by setting thumb vs. hand heat range for an even more customized level of comfort.
  • MESSAGE CENTER DISPLAY: Keeps a rider aware of sled operating conditions and other important information. Large buttons can be operated with gloved hands and the brightly lit display is easily readable in all light conditions.
  • INTEGRATED STORAGE: Storage comes standard under the seat and behind the gauge with additional accessory storage options available for greater versatility. The standard integrated underseat storage provides 8.1 Liters of storage space with the behind the gauge offering and additional 7.6 Liters.
