Meet the **2027 Polaris ProStar S4 TITAN® Adventure Ultimate 155 1.5** in ****—a snowmobile that looks ready to lead the pack before it even fires up. It’s the kind of machine that makes winter plans form instantly: a longer loop, a farther lake, one more overlook before heading back. Built as a **widetrack touring** sled, it’s designed to turn “we could” into “we did,” with the stability and comfort to keep the good miles rolling.



At the heart of this TITAN is the **ProStar™ 998cc** **liquid-cooled**, **4-stroke** **parallel twin** with **DOHC** precision and **fuel injection**, so throttle response stays crisp when the day gets long and the temps get low. Tap the **electric start**, settle your thumb on the **thumb throttle**, and let the **CVT** do what it does best—smoothly translating power through its **belt** drive. When the trail narrows or the parking spot gets tight, having **reverse** on hand feels like a small luxury you’ll quickly refuse to live without.



This sled carries its size with purpose. With an overall length of **133 inches** and a planted stance adjustable between **39 and 41 inches**, it’s confident at speed and steady when conditions get chopped up. The **AXYS® aluminum frame** keeps things strong where it matters, while practical touches—like a **belt guard** and **snow guard**—help you focus on the ride instead of the mess.



The suspension package is tuned for real-world touring comfort, not just perfect-day cruising. Up front, the **High Clearence IFS** uses an **independent A-arm** setup with **9 inches of travel**, paired with **adjustable hydraulic Polaris IFP** shocks and **shock-mounted adjustment** for dialing in feel. Out back, the **BackTrak20** rear suspension brings a generous **16.5 inches of travel**, supported by **two** rear shocks (again, **adjustable hydraulic Polaris IFP**) plus a **Fox® QS3** center shock with a **remote reservoir**. Translation: you can tailor the ride to the day—whether that means floating over stutter bumps or staying composed when the trail gets unpredictable.



And then there’s the track: a **Cobra Track** measuring **155 inches long** by **20 inches wide**, with **1.5-inch lugs**. That big footprint is exactly what you want from a widetrack machine—confidence in softer snow, steadiness when you’re carrying a passenger, and the kind of traction that makes you comfortable exploring farther from the groomed ribbon. Steering stays direct and familiar with **manual handlebar control**, while the **TrailBreaker** plastic skis and **carbide** skags help keep the front end honest.



Touring is where this TITAN really earns its name. The **two-piece seat** is built for **two**, with a dedicated **passenger backrest**—a simple detail that turns “just a ride” into an all-day invitation. Add **heated hand grips for both driver and passenger**, and suddenly those colder mornings (and longer returns) feel a lot more doable. The **high, folding LED** setup keeps the way ahead bright, while a clear set of warnings and readouts—like a **fuel level gauge** and **temperature warning light**—helps you stay in the moment without losing track of the basics.



When it’s time to navigate, the **RIDE COMMAND™ GPS** is ready, and the experience stays modern with **Bluetooth® audio** and **mobile app instrumentation**. It’s the kind of cockpit that makes you feel organized even when you’re wandering on purpose.



Finish the day by hooking up your plans—literally—thanks to the **rear receiver hitch**. With **12.6 gallons** of fuel capacity and a touring-focused build, this TITAN is ready for winter the way it should be: bigger routes, better comfort, and a whole lot of “let’s go see.”
