Dressed in ****, this 2027 Polaris ProStar S4 INDY® Adventure 137 looks like it was built for the kind of winter days that start with “let’s just go for a quick ride” and somehow end hours later with a face-full of fresh air and a whole lot of new mileage. It’s a trail sled with a playful attitude—ready to turn groomed runs into your personal playground, while keeping comfort and confidence along for the ride.
At the heart of the fun is the **ProStar™** powerplant: a **998cc**, **liquid-cooled**, **DOHC**, **parallel-twin** with **fuel injection** that runs on **regular gas**. Hit the **electric start**, settle your thumb on the **thumb throttle**, and let the **CVT** do what it does best—keeping the power smooth and responsive as the trail twists, opens up, and changes character. When it’s time to back out of a parking spot or pivot in a tight area, you’ve got **reverse** on board, because convenience counts when the snow’s deep and the day’s still young.
The ride feels purposeful and planted thanks to the **MATRYX aluminum frame**, with a stance that sits at **42.5 inches**—stable, predictable, and confidence-inspiring when the pace picks up. Up front, the **independent A-arm** suspension teams with **MATRYX**-branded geometry and **Polaris TS adjustable gas shocks with remote reservoirs**, delivering **9.5 inches** of travel to help keep the skis calm and tracking clean. Those **Pro-Steer™ composite skis** with **carbide** skags are there to hold a line and help you feel what the trail is doing under you, not just react to it.
Out back, the **PRO-CC** rear suspension brings **16.2 inches** of travel and a trio of matching **Polaris TS adjustable gas shocks with remote reservoirs** (rear and center), giving you the tuning range to match conditions—whether you’re chasing buttery groomers, dealing with late-day chop, or carrying a passenger and gear. And with a **Cobra Track** measuring **137 inches** long by **15 inches** wide and a **1.35-inch** lug profile, this sled is happy digging in and driving forward with a confident, “keep going” feel that makes trail miles disappear.
Speaking of miles: comfort is a big part of what makes an Adventure sled an Adventure sled. The **two-piece seat** is set up for **two**, with a dedicated **passenger backrest**, so your co-pilot isn’t just “coming along”—they’re actually enjoying the ride. Practical touches like **hand guards**, a **belt guard**, a **snow guard**, and **skid-resistant** running boards keep the experience cleaner, safer, and more controlled when conditions get messy. A **high, tinted, folding windshield** helps cut fatigue on longer runs, and the **heated driver hand grips** keep your hands happier when winter decides to remind you who’s in charge.
When it’s time to slow things down, the **S4 Stealth** brake system with a **hydraulic disc** rear brake delivers the kind of braking feel you want on the trail—confident, consistent, and ready for quick adjustments as corners appear.
And because modern adventures come with modern expectations, this INDY Adventure 137 brings **RIDE COMMAND™ GPS**, **Bluetooth® Audio**, and **mobile app instrumentation** into the mix. Whether you’re keeping tabs on where you are, queuing up a soundtrack, or just appreciating the convenience of clear info at a glance, it’s all designed to make the ride feel connected without distracting from the reason you’re out there in the first place.
In ****, this 2027 Polaris ProStar S4 INDY® Adventure 137 isn’t just ready for winter—it’s ready to make you look for excuses to ride it. Whether you’re piloting solo or sharing the experience, it’s built to turn “trail riding” into a full-on winter ritual.
