Meet the **2027 Polaris ProStar S4 TITAN® Adventure Ultimate 155 1.5**, a widetrack touring snowmobile that’s basically a winter expedition you can point at the horizon and confidently commit to. This particular one wears ****, and it brings a bold, purposeful look that fits the machine’s “go farther, stay longer” personality—whether you’re threading through timberline trails or cruising frozen lakes with a passenger along for the story.
At the heart of the ride is the **ProStar™ 998cc** **liquid-cooled**, **DOHC**, **parallel twin**—a **2-cylinder**, **4-stroke** setup that blends smooth power with cold-weather composure. It’s **fuel injected** and happy on **regular gas**, with **electric start** to keep your mornings simple. Power flows through a **CVT** with **belt** drive, and when the trail narrows or the parking spot gets awkward, **reverse** is ready to save you from the classic “snowmobile shuffle.”
The TITAN Adventure Ultimate is built on an **AXYS® aluminum frame**, giving it a sturdy backbone without feeling like a sled that forgot how to have fun. It’s a big, confidence-inspiring platform—**133 inches long** and **46.5 inches wide**—with an adjustable ski stance that can be set between **39 and 41 inches**. Up front, the **High Clearence IFS** with **independent A-arms** delivers **9 inches of travel**, tuned with **shock-mounted adjustment** and **Polaris IFP adjustable hydraulic shocks** (coil-over style). Out back, the **BackTrak20** rear suspension brings **16.5 inches of travel**, running **two rear shocks** plus a **Fox® QS3** center shock with a **remote reservoir**—all geared toward keeping the ride composed when the trail gets choppy, the snow gets inconsistent, or the day gets long.
And this is where the “widetrack” part earns its reputation. The **Cobra Track** measures **155 inches** long and a full **20 inches** wide, with **1.5-inch lugs**—a footprint that’s all about bite, float, and stability. Pair that with **TrailBreaker** skis (plastic) and **carbide** skags, and you’ve got steering feel that stays predictable when conditions change from packed trail to fresh snow to windblown hardpack.
Touring comfort is baked in, not bolted on. The **two-piece seat** is designed for both **driver and passenger**, wrapped in **vinyl**, and the passenger gets a dedicated **backrest**—because “adventure” is more fun when your co-pilot is still smiling at mile 60. Cold hands? Not here. **Heated grips for both driver and passenger** bring the kind of warmth that turns “we should head back” into “let’s take the long way.” There’s also a **high, folding LED windshield**, ready to cut the wind when you want extra protection and fold away when you’d rather open up your view.
On the tech side, Polaris keeps you connected without making the ride feel complicated. **RIDE COMMAND™ GPS** helps you keep your bearings, and the onboard setup supports **Bluetooth® audio** plus **mobile app instrumentation**. Add in smart at-a-glance essentials like a **fuel level gauge**, a **temperature warning light**, and you’ve got the kind of cockpit that encourages exploring further—confidently, not guesswork-first.
When it’s time to slow things down, the **Titan Hydraulic** braking system delivers with a **hydraulic rear disc**. And when it’s time to bring gear (or help someone else get unstuck), the **receiver-style rear hitch** is there to back up the sled’s hardworking attitude.
Big, capable, and genuinely enjoyable, this **** TITAN Adventure Ultimate doesn’t just get you through winter—it invites you to chase it.
