Expedition® SE 900 ACE 154 1.8

Description

Meet the 2027 Ski-Doo Expedition® SE 900 ACE™ 154 1.8 in ****—a snowmobile that’s equal parts weekday workhorse and weekend escape plan. It’s built in that sweet spot where **sport-utility** capability and **touring** comfort overlap, so you can head out for a long loop, bring a passenger along, and still have the confidence to turn down the next unplowed trail just because it looks interesting.

At the heart of it is a **Rotax® 900 ACE™**—a **liquid-cooled**, **4-stroke**, **horizontal in-line 3-cylinder** engine with **899 cc** of displacement and **12 valves** controlled by **DOHC**. Translation: smooth, consistent power that feels refined when you’re cruising, but still responds when the trail opens up. With **95 bhp (70.9 kW)** on tap and **fuel injection** sipping **regular gas**, it’s ready for long days without demanding high-maintenance habits. Push-button **electric start** gets you going quickly, and a **speed governor** is there when you want a more controlled pace.

Power delivery stays simple and rider-friendly thanks to a **CVT transmission** with belt drive and a **pDrive clutch**. You also get the practical stuff that matters in real riding: **reverse**, plus **high/low range** to help when conditions get heavy, loads get real, or you’re maneuvering in tight spots. The **thumb throttle** keeps control natural and familiar—whether you’re threading through trees or easing into a snowy parking lot.

The Expedition SE’s size gives it a planted, confident feel. It measures **129.1 inches long**, **46.1 inches wide**, and **61.5 inches high**, with a **39-inch ski stance** for stable tracking. Up front, the **RAS X** suspension uses an **independent double A-arm** design with **8.7 inches** of travel, paired with **adjustable KYB gas shocks** and coil-over support to help soak up chatter and keep steering precise. Out back, **uMotion** rear suspension with **10.5 inches** of travel teams up with **two rear shocks** and a **KYB adjustable center shock**, plus an **air shock** in the mix—great for balancing comfort and control as the day (and the terrain) changes. Even better, you can fine-tune feel on the fly with **handlebar-mounted adjustment**.

Traction and flotation come from the **Silent Cobra WT** track—**154 inches long**, a wide **20 inches**, with **1.8-inch lugs** that bite when the snow gets deep and keep things confident when it’s loose. Up front, **Pilot™ skis** (plastic) and **carbide skags** help the sled hold a line and stay predictable when the trail turns hard-packed or mixed.

Utility is where this machine quietly flexes. With a **towing capacity of 1,200 lbs** and a **receiver-style rear hitch**, it’s ready to help at the cabin, haul gear, or pull what needs pulling when winter doesn’t care about your schedule. You’ve also got serious room for the essentials: **5.6 cu ft (135 L)** of storage capacity, plus a **hard-vinyl rear rack storage** setup and **rear rack rails** for extra carrying confidence. The sled’s **REV Gen5 aluminum frame** keeps things strong, while practical protection like a **full-length skid plate**, **belt guard**, and **snow guard** are built in for the realities of daily riding.

And because the best rides are the ones you want to stay out on, the comfort and safety details are spot-on: a **two-piece, two-up vinyl seat**, a **fixed passenger backrest**, **heated grips for both driver and passenger** (adjustable), and **high LED lighting** to keep night rides bright. A **Brembo® hydraulic disc brake** with adjustability adds reassuring control, while gauges provide **fuel level** and **temperature warnings** at a glance. Security is covered, too, with the **DESS engine immobilizer**.

Finished in ****, this Expedition SE looks as ready as it rides—built for long miles, real utility, and the kind of winter days that start as “just a quick ride” and end with stories. Limited availability means it won’t hang around—so if this is your kind of snow season, it’s worth seeing in person.
