Meet the 2027 Polaris ProStar S4 INDY® XC® 137 in ****—a trail sled that looks fast standing still and feels even quicker once the snow starts blurring past the windshield. It’s the kind of machine that turns a “quick ride” into an all-day mission: one more lake loop, one more twisty section through the trees, one more stop only because you remembered you’re supposed to eat lunch. And yes, this model is also offered in **Gloss Black** and **INDY® Red / White Lightning / Gloss Black**—but there’s something about **** that just fits the vibe of an XC built to hustle.
At the heart of it is the ProStar™ parallel-twin—**998cc**, **liquid-cooled**, and **4-stroke**, with **DOHC** breathing and **fuel injection** that keeps throttle response crisp when the trail goes from groomed and glassy to chewed-up and chaotic. The **electric start** means the day begins with a button press, not a workout, and it runs on **regular fuel** with **gas / oil injected** convenience—simple stuff that matters when you’re stacking miles. Power is routed through a **CVT** with **belt drive**, and when you need to back out of a tight parking spot or a snowbank “oops,” you’ve got **reverse** on tap. Thumb throttle, bars in your hands, and the trail in front of you—exactly as it should be.
The MATRYX aluminum frame gives this INDY® a purposeful feel: planted when you’re on the gas, predictable when you’re setting up for the next corner. Up front, the **independent A-arm** suspension delivers **9.5 inches** of travel, paired with **Polaris TS adjustable gas shocks with remote reservoirs** (coil-over, because control matters). Out back, the **PRO-CC** rear suspension brings **16.2 inches** of travel with **two rear shocks**, plus a **Polaris TS center shock**, all adjustable with shock-mounted controls—so you can dial things in for your pace, your trail, and your kind of “fun.”
And this sled is built to track and carve, not wander. The **Pro-Steer™ composite skis** with **dual carbide** skags bite with intent, while the **Cobra Track**—a **137-inch** length, **15-inch** width, and **1.35-inch** lug profile—bridges that sweet spot between corner-happy handling and trail-eating stability. It’s the setup that makes you trust the front end, then rewards that trust with clean lines through the turns.
Comfort and practicality come baked in, too. The cockpit is focused: a **one-piece vinyl seat** for a single rider, **rubber grips**, **hand guards**, and **heated driver grips** that adjust so you can keep your hands happy when the temps drop. Skid-resistant running boards help you stay planted when you’re shifting body position, and there’s the kind of smart protection you appreciate after the fact—**belt guard** and **snow guard** included.
When the ride stretches into unfamiliar territory, the onboard tech helps you stay in the moment. **RIDE COMMAND™ GPS** puts navigation where you need it, and the system supports **Bluetooth® audio** plus **mobile app instrumentation**—great for keeping your world connected without killing the vibe. You also get clear, simple alerts: a **fuel level gauge** and a **temperature warning light**, backed by bright **LED** lighting. Add a **mid-height tinted windshield**, and you’ve got a calmer pocket of air when the pace picks up.
With an **11.5-gallon** fuel capacity, this INDY® XC® 137 is ready for real trail days, not just quick spins around the neighborhood. If you’re looking for a new snowmobile that blends strong 4-stroke punch, adjustable suspension, confident steering, and a look that stands out in ****, this one’s ready to make winter your favorite season again.
