READY FOR WHATEVER YOU CAN COME UP WITHWhen pushing yourself and your sled to the limit in deep snow, you might want some extrastability for those landings...this Freeride 154's S-38 front end is the ideal combo of stability and deep snow carving agility. ROTAX 850 E-TEC ENGINE: 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. E-TEC SHOT ENGINE STARTER: 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. REV GEN4 PLATFORM: 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.
