2027 Polaris ProStar S4 INDY® XC® 137 7S

Meet the 2027 Polaris ProStar S4 INDY® XC® 137 7S—a trail sled that’s basically a permission slip to turn winter into your favorite season. Dressed in , it brings a crisp, purposeful look that fits right in at the trailhead and still stands out when the snow starts flying.



At the heart of it is the liquid-cooled ProStar™ 998cc parallel twin—a 4-stroke, DOHC setup that’s built for long days and fast miles. Tap the electric start, settle your thumb on the thumb throttle, and let the fuel-injected response do its thing. Power runs through a CVT with belt drive, and when the trail tightens up or parking gets tricky, you’ve got reverse ready to save the day.



The ride is all about control and confidence. The MATRYX aluminum frame keeps things planted and precise, while the independent A-arm front suspension and PRO-CC rear suspension work together to smooth out chatter and surprise bumps. With 9.5 inches of front travel and 16.2 inches of rear travel, plus Polaris TS adjustable gas shocks with remote reservoirs up front, rear, and center, you can dial in your setup and keep charging when the conditions change. Up front, Pro-Steer™ composite skis with dual-carbide skags help the sled hold a line like it means it.



Out back, the Cobra Track—137 x 15 with 1.35-inch lugs—brings the bite for acceleration and the hookup to keep momentum where it belongs: moving forward.



When it’s time to manage speed, the S4 Stealth hydraulic disc brake delivers clean, predictable stopping power. And because comfort matters when the miles add up, you get a one-piece vinyl seat, heated, adjustable driver grips, and practical touches like hand guards, a belt guard, snow guard, and skid-resistant running boards.



Top it off with RIDE COMMAND™ GPS, Bluetooth® audio, and mobile app instrumentation, and this INDY® XC® becomes the kind of sled that turns “just a quick ride” into an all-day story.
