Dressed in **Gloss Black**, this 2027 Polaris ProStar S4 TITAN® Adventure 155 looks like it was poured out of midnight and shaped into a purpose-built winter machine. It has that clean, confident “point it at the horizon” attitude—equal parts refined touring comfort and widetrack muscle—ready for long, story-worthy days when the trail signs get sparse and the snowbanks get tall.
At the heart of it is the **ProStar™** powerplant: a **998cc**, **liquid-cooled**, **DOHC**, **4-stroke** **parallel twin** that starts with the push of an **electric** button and runs on **regular gas**. The delivery feels modern and smooth thanks to **fuel injection**, and it pairs with a **CVT** setup using **belt drive**, so it’s happy to cruise, climb, and keep rolling when the ride turns into a “let’s see what’s back there” detour. Add **reverse**, and even tight trail-side turnarounds feel more like a simple reset than a wrestling match.
This TITAN Adventure is built for real-world winter travel. Its **AXYS® aluminum frame** brings strength with a purposeful feel, while the overall stance—**46.5 inches wide** with an adjustable ski stance (from **39 to 41 inches**)—gives it a planted, confident footprint. Up front, the **High Clearence IFS independent A-arm** suspension with **9 inches** of travel and **Polaris IFP adjustable hydraulic shocks** helps keep steering predictable when the trail turns choppy or the snow gets rutted. Out back, the **BackTrak20** rear suspension stretches to **16.5 inches** of travel, supported by **two rear shocks** plus a **Fox® QS3** center shock with a **remote reservoir**, so you can tailor the feel and keep the ride composed as conditions change.
And then there’s the part that makes this machine a true widetrack adventurer: a **Cobra Track** measuring **155 inches long** and **20 inches wide**, with **1.5-inch lugs**. That wide, long contact patch brings the kind of steady traction and float you appreciate when the snow is deep, the load is real, or the day is just getting started.
Touring comfort is clearly part of the plan. The **two-piece seat** (vinyl, driver and passenger) and a dedicated **passenger backrest** make it easy to bring company without making them “hang on and hope.” Both rider and passenger get **heated hand grips**, and they’re **adjustable**, so cold fingers don’t get a vote in how far you go. You’ll also find smart, no-nonsense monitoring with a **fuel level gauge** plus a **temperature warning light**, because confidence comes from knowing what’s happening under you.
Practical touches show up everywhere, too: **skid-resistant** running boards, **belt guard**, **snow guard**, and **Titan Hydraulic** braking with a **hydraulic disc** rear brake for controlled stops. The **TrailBreaker** skis (plastic) track with **carbide skags** for bite, and when the day calls for utility, the **receiver rear hitch** is ready to help you bring the right gear along.
The result is a snowmobile that feels like a winter expedition tool—only sleeker, quieter in its confidence, and undeniably sharp in **Gloss Black**. It’s not here for a quick lap; it’s here for the long way around.
