LEAVE YOUR LIMITATIONS BEHIND
From extreme backcountry to race-proven trail performance, the Backcountry X-RS pushes the very definition of the 50-50 crossover sled. It allows every ride to go from technical deep powder to thrashing the trails in an instant.

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.
