FOR WHEREVER YOUR AMBITION TAKES YOU
Ski-Doo Snowmobile Backcountry X
The 2021 Backcountry X delivers a premiere 50/50 crossover sled with a combination of precise, responsive trail handling and effortless off-trail prowess. Riders can surgically dissect trails or dive into tight tree lines and shred untracked powder.

MORE POWER YOU CAN FEEL
The most powerful 2-stroke engine in the industry.* It pumps out 10 more horsepower (165 hp) than its predecessor, but its responsiveness is what really shines. With the new pDrive primary clutch, it’s 30% quicker responding than the 800R E-TEC giving you the instant control you demand.
*Observed HP measured on internal dyno test in optimal conditions for 2-stroke engines. 

EASIEST STARTING
Push-button starting with almost no added weight. After an initial pull-start, the engine charges an ultracapacitor. Pushing the handlebar SHOT button for subsequent starts uses energy stored in the ultracapacitor to turn the magneto into an electric motor that rotates the flywheel, and with E-TEC technology, starts the engine. Eliminates nearly 20 lb. (9 kg) compared to conventional electric start. SHOT starting is only possible with Ski-Doo-exclusive E-TEC technology.

QUICK, EFFICIENT, EASY
A major factor in the quickness of REV Gen4 sleds is the new pDrive clutch. Fast and friction-free dual rollers transfer torque in place of traditional sliding buttons on this 100% new clutch. The oversize rollers with needle bearings, wide flyweights and shaft-on-shaft design emphasize smooth operation and long life. Ultra-responsive shifting, impressive RPM consistency and 2.8 lb./ 1.3 kg lighter than the TRA VII.

PESONALIZED ADVENTURE
Wide screen full-color display lets riders truly customize their ride from behind the bars. Choose your preferred sled info, and see app integrated information in a split-screen format with GPS, Bluetooth music, helmet-to-helmet communication and more.

NEXT GENERATION OF A LEGEND
You’ll realize the benefits of our trail and mountain teams’ close cooperation in developing this sled because it has all the right features for both types of riding. It’s incredibly responsive and agile in cornering and boondocking, thanks to its centralized masses and light weight. Not to mention the power and instant response of the 850 E-TEC engine is ideal for hammering out of corners and powering out of a hole.

CROSSOVER CONTROL AND CARVING
Crossover-specific suspension uses best principles of the rMotion trail and tMotion mountain skids for confident cornering and agile boondocking – such as rigid front and rear arms with excellent weight transfer. It also features a rising-rate motion ratio, like the latest generation of Ski-Doo rear suspensions, to provide superior control and comfort. Tipped rails enable better cornering, boost top-end speed and fuel efficiency.

CROSSOVER PRECISION
Similar geometry and steering to the RAS 3 mountain front end for capability and light steering feel on- and off-trail. Optimized for crossover usage, two ski stance positions dial in handling: 40.1 in. (102 cm) or 38.4 in. (97.5 cm).

ALL CLEAR
Massive, strategically shaped openings keep the boards clear. A tall extruded edge adds stiffness and has aggressive boot grips.

KYB PRO 36 REAR SHOCK RACE-PROVEN CAPABILITY
Race-proven aluminum shock with no-tool compression damping adjustment. Rebuildable/revalvable design.
