2027 Polaris ProStar S4 INDY® XC® 137 7S

Meet the ** 2027 Polaris ProStar S4 INDY® XC® 137 7S** in ****—a trail machine that looks as sharp standing still as it feels at speed. It’s the kind of sled that makes a “quick loop” turn into a full-on day plan, because once you’re settled into its one-piece vinyl seat, hands wrapped around the rubber grips, it’s hard to resist seeing what’s around the next bend.



At the heart of this INDY XC is Polaris’ **ProStar™** power: a **998cc**, **liquid-cooled**, **DOHC**, **2-cylinder** **4-stroke** parallel twin that’s built to deliver smooth, modern response. It runs **regular fuel**, uses **fuel injection**, and lights off with an **electric start**—so you’re not negotiating with the weather before the ride even begins. Power flows through a **CVT transmission** with **belt drive**, backed up by **reverse** for those real-life moments when the trailhead parking lot is tighter than expected. And with a **thumb throttle**, control stays intuitive—point, press, and go.



The personality of this sled really comes alive on-trail, where the **MATRYX aluminum frame** sets the tone: purposeful, light-feeling, and ready to change direction without drama. Up front, the **independent A-arm** suspension paired with **Polaris TS adjustable gas shocks with remote reservoirs** (and shock-mounted adjustment) is tuned for riders who want to drive the trail, not just survive it. With **9.5 inches of front travel**, it’s prepared for the chop and the surprises that show up halfway through a long day.



Out back, the ride stays composed and confident thanks to the **PRO-CC rear suspension** with **16.2 inches of travel** and a **two-shock rear setup**, plus a **Polaris TS center shock**—all adjustable gas shocks with remote reservoirs, all ready to be dialed to your style. It’s the sort of suspension package that encourages you to stay on the throttle a little longer and trust the sled to stay planted.



And planted is exactly what the **Cobra Track** aims to be: a **137-inch** track with a **15-inch width** and **1.35-inch lugs**—a sweet spot for trail dominance with the bite to keep things fun when conditions get loose. Up front, **Pro-Steer™ composite skis** with **dual carbide** skags help the sled hold its line with that “on rails” feel when the corners start stacking up.



When it’s time to rein things in, the **S4 Stealth** brake system brings confident stopping power via a **hydraulic disc rear brake**—smooth, controlled, and reassuring when the pace picks up or the trail tightens.



This INDY XC also brings the kind of creature comforts that make long miles feel shorter. A **mid-height, tinted windshield** helps take the edge off the wind. **Heated, adjustable hand grips** keep your hands happier as the temps drop. And with **LED lighting**, you’re ready for those late-afternoon runs that accidentally become after-dark adventures.



Then there’s the tech: **RIDE COMMAND™ GPS**, **Bluetooth® audio**, and **mobile app instrumentation**, plus clear warnings like a **temperature light** and a **fuel gauge** to keep you informed without breaking the flow of the ride. Add in practical touches like **hand guards**, a **belt guard**, a **snow guard**, and **skid-resistant** footing—details that quietly make every mile better.



Sized at **120 inches long**, **47 inches wide**, and carrying **11.5 gallons** of fuel, this **596 lb (dry)** trail sled is built to cover ground and do it with attitude. In ****, it doesn’t just show up—it announces itself, then backs it up with a ride that’s eager, capable, and undeniably fun.
