Meet the ** 2027 Polaris ProStar S4 INDY® XC® 137 7S**—a trail sled that looks fast even when it’s parked, especially in ****. It’s the kind of snowmobile that makes you start planning “quick” rides that somehow turn into all-day missions, because everything about it is built to keep you moving, comfortable, and confidently in control when the trail gets playful.
At the heart of it is Polaris’ **ProStar™** power: a **998cc**, **liquid-cooled**, **DOHC**, **parallel-twin** with **fuel injection** and a convenient **electric start**. It runs on **regular fuel**, and the power delivery feels right at home in the trail world—strong, smooth, and ready to respond the moment your **thumb throttle** says so. Power is managed through a **CVT transmission** with **belt drive**, paired with a **P-22 / TEAM BOS** clutch setup, and when it’s time to back out of a tight spot or a crowded staging area, you’ll be glad it includes **reverse**.
The ride experience is anchored by the **MATRYX aluminum frame**, giving the sled a precise, purposeful feel without forgetting durability. You’re positioned where you want to be with the **driver-focused floorboard location**, and details like **skid-resistant** footing, **rubber hand grips**, **hand guards**, a **belt guard**, and a **snow guard** keep the day more comfortable and less fussy—because winter adventures should be about the ride, not about battling little annoyances.
Up front, the **independent A-arm** suspension with **9.5 inches** of travel helps the sled stay composed when the trail turns choppy. Matched with **Polaris TS adjustable gas shocks with remote reservoirs** (and coil-over design), you’ve got the ability to fine-tune feel through **shock-mounted adjustment**—the kind of setup that can make a long route feel shorter and a rough section feel way more manageable. Out back, the **PRO-CC rear suspension** brings **16.2 inches** of travel with **two rear shocks**, plus a **Polaris TS center shock**, all in the same adjustable, remote-reservoir style. In plain terms: it’s ready for spirited trail pace, changing conditions, and those stretches where you’re chasing the horizon.
Steering is straightforward and connected with **manual handlebar control**, and the front end rides on **Pro-Steer™ composite skis** with **dual carbide** skags for confident bite. Underneath, the **Cobra Track**—a **137-inch** long, **15-inch** wide track with **1.35-inch** lugs—brings the traction to hook up when the snow is fresh, the corners are calling, or the trail turns from hardpack to surprise softness.
And because modern rides should feel modern, this INDY XC 137 7S brings tech you’ll actually use. **RIDE COMMAND™ GPS** is on board, along with **Bluetooth® audio**, **mobile app instrumentation**, and clear warnings like a **temperature light** and a **fuel gauge**. The **LED** lighting (with a **tinted**, **mid-height** setup) keeps visibility sharp, and when the cold really settles in, you’ll appreciate the **adjustable heated hand grips** that help keep your hands happy mile after mile.
Sized at **120 inches** long and **47 inches** wide, with a **dry weight of 596 lbs** and an **11.5-gallon** fuel capacity, it’s a trail sled that’s prepared for real distance. The **one-piece vinyl seat** keeps the cockpit simple and focused—this is a one-rider machine built for the person who wants to lead the pace, not follow it.
If you want a trail snowmobile that blends responsive 4-stroke power, adjustable suspension confidence, smart onboard tech, and a standout look in ****, this 2027 INDY® XC® 137 7S is ready to turn winter into your favorite season.
