Description
Meet the ** 2027 Polaris ProStar S4 TITAN® Adventure Ultimate 155 1.8**, a widetrack touring snowmobile that’s basically a winter road-trip machine disguised as a snow-eating beast. Dressed in ****, it looks ready to lead the pack from the parking lot to the far side of the map—clean, bold, and perfectly suited to a sled that’s built to roam.
At the heart of this TITAN is the **ProStar™ 998cc** liquid-cooled **parallel-twin**. With **DOHC** breathing and **fuel injection** handling the details, it’s the kind of powertrain that feels eager when you thumb the throttle, yet composed when the day turns into an all-day ride. The **CVT transmission** keeps things smooth and responsive, and when it’s time to pivot in tight spots or maneuver at the cabin, **reverse** is right there to save the day (and your pride). It’s happy on **regular gas**, too—because adventure is already expensive enough.
This sled’s whole vibe is “go farther, stay comfortable.” The **two-piece seat** is set up for **two**, with a dedicated **passenger backrest** so your co-pilot can actually relax instead of doing an endless core workout. Cold hands? Not today. **Heated grips for both driver and passenger** plus an **adjustable high, folding windshield** let you tune your comfort to the conditions—windy lake crossings, tree-lined trails, or that late-afternoon temperature drop you totally saw coming.
Point it down the trail and the chassis feels purpose-built. The **AXYS® aluminum frame** keeps things strong and predictable, while the **High Clearance IFS** independent A-arm front suspension and **BackTrak20** rear suspension work together to keep the ride planted. With **9 inches** of front travel and a generous **16.5 inches** out back, you get the confidence to carry speed through changing trail surfaces without feeling like you’re getting tossed around. The shock package adds a nice layer of control: **Polaris IFP adjustable hydraulic shocks** up front and in the rear, plus a **Fox® QS3 center shock** with a remote reservoir when you want to fine-tune how it behaves.
And then there’s the footprint—because a TITAN should leave a proper signature. The **Cobra Track** measures **155 inches long** and a full **20 inches wide**, with **1.8-inch lugs** to help it bite and keep moving when the snow gets deeper or the trail gets chewed up. Pair that with **TrailBreaker** skis and **carbide skags**, and you’ve got steering feel you can trust when the pace picks up. Manual steering keeps the connection direct: hands on the bars, eyes up, and that satisfying sense that you’re truly driving the terrain.
Practical touches are baked in, too. There’s a **receiver-style rear hitch**, so bringing gear along (or bringing something back) fits the mission. **Titan hydraulic brakes** with a **hydraulic disc rear brake** give you confident stopping power, and the sled keeps you informed with smart warnings and readouts like a **fuel gauge** and a **temperature warning light**.
For navigating the day—and making it more fun—the **RIDE COMMAND™ GPS** system teams up with **Bluetooth® audio** and **mobile app instrumentation**. Whether you’re plotting a new route, keeping tabs on the ride, or just adding a soundtrack to the miles, it’s all right where you want it.
In ****, this 2027 TITAN Adventure Ultimate isn’t just ready for winter—it’s ready for the kind of winter stories you’ll tell all year.
