Description

Meet the 2027 Polaris ProStar S4 TITAN® Adventure Ultimate 155 1.5 in —a snowmobile that’s built for the riders who don’t stop when the trail gets long, the temps drop, or the day turns into “one more mile.”



At the heart of this widetrack touring machine is a liquid-cooled ProStar™ 998cc parallel-twin with DOHC breathing and fuel injection, so it’s ready to fire up with electric start and run strong on regular gas. Power is managed through a CVT with a P-22 / TEAM BOS clutch and a belt drive, giving you smooth, predictable pull when you’re cruising, climbing, or rolling through fresh snow. And when it’s time to maneuver in tight spots, reverse is right there to make life easy.



The TITAN® Adventure Ultimate is made for covering ground comfortably. Up front, the High Clearance IFS independent A-arm suspension provides 9 inches of travel, paired with adjustable Polaris IFP shocks. Out back, the BackTrak20 rear suspension delivers a generous 16.5 inches of travel, supported by Polaris IFP rear shocks and a Fox® QS3 center shock with a remote reservoir—so you can dial in the ride when conditions change.



Its footprint means business: a 155" Cobra Track that’s 20" wide with 1.5" lugs to keep you moving with confidence, plus TrailBreaker skis with carbide skags for planted steering. Add in the AXYS® aluminum frame, a Titan hydraulic brake with hydraulic disc rear braking, and you’ve got a sled that feels composed even when the day gets ambitious.



And because adventures are better shared, the two-piece seat welcomes a passenger with a dedicated backrest, while heated grips for both rider and passenger and a high, folding LED windshield help keep the cold at bay.



When the route matters as much as the ride, RIDE COMMAND™ GPS and mobile app instrumentation keep you connected, and Bluetooth® audio keeps the mood rolling. Need utility? There’s a receiver rear hitch ready for the job.



In , this TITAN® doesn’t just look the part—it’s ready to write winter stories, two-up, mile after mile.
