Meet the 2027 Polaris ProStar S4 INDY® SP 137, a trail sled that’s built for the kind of winter days where “one more loop” turns into “how is it already dark?” Finished in ****, it wears its attitude well—sharp, modern, and ready to look just as good idling at the staging lot as it does throwing a crisp rooster tail of powder off the trail edge.
Twist your thumb and the ProStar™ parallel-twin comes alive with smooth, four-stroke confidence. With **998cc** on tap, liquid cooling, and fuel injection sipping regular gas, it’s the kind of power that feels eager without feeling edgy—happy to cruise, but even happier when you ask for more. The CVT setup with belt drive keeps the response clean and consistent, and when the trail gets tight or the parking situation gets awkward, **reverse** is there to save the day (and your dignity). Electric start means fewer cold-finger moments and more “helmet on, go now.”
This INDY SP 137 is sized to feel nimble and planted at the same time. At **120 inches long** and **47 inches wide**, it threads through wooded corridors with confidence, and the **42.5-inch ski stance** gives it a stable, predictable feel when the trail gets rutted or the corners come fast. Up front, the Pro-Steer™ composite skis with carbide skags bite in with purpose, and the independent A-arm front suspension delivers **9.5 inches** of travel to help keep the ride composed when the groomer’s work is… let’s call it “vintage.”
Out back, the PRO-CC rear suspension brings **16.2 inches** of travel and a two-shock setup that’s ready to handle chatter bumps, rolling dips, and those surprise hits that appear out of nowhere on a late-afternoon run. Adjustable gas IFP shocks (front, rear, and center) let you fine-tune the feel, so whether you like your sled plush and forgiving or crisp and connected, you can dial it in without making it a whole project.
The **RipSaw II 137 x 15** track with **1-inch lugs** is a sweet spot for trail riders: enough footprint for confident drive and stability, with a length that still feels playful when you start linking corners. And when it’s time to rein things in, the S4 Stealth hydraulic disc brake gives you a controlled, reassuring stop—because fun is better when it’s paired with confidence.
Polaris’ MATRYX aluminum frame anchors the whole experience with a lightweight, modern feel, while practical touches—like a belt guard, hand guards, a snow guard, and skid-resistant running boards—keep the day smoother and the ride more secure. Settle into the one-piece vinyl seat, glance at the gauge warnings for fuel level and temperature, and watch the world light up through LED lighting with a tinted lens for a clean, stealthy look. Add heated, adjustable grips, and suddenly that “just a quick ride” plan doesn’t sound so unrealistic after all.
If you’re after a trail sled that balances muscle, manners, and long-haul comfort—and you want it in **** so it stands out even when the snowbanks all look the same—this ProStar S4 INDY® SP 137 is ready to make winter your favorite season again.
