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.  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. Key to the Freeride’s agility is the extreme mass centralization of the 4th generation REV platform. The trademark pyramidal frame, new die-cast aluminum front suspension module and new heat exchanger design ensure it’s strong, yet lightweight. A major factor in the quickness of REV sleds is the new pDrive clutch. Fast and friction-free dual rollers transfer torque in place of traditional sliding buttons on this 100% 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. These shocks are standard on the MXZx 600RS race sled - so you know they're extremely capable and durable for control in the toughest conditions. Remote reservoir design for performance and they are a rebuildable/revalvable. Easy Adjust compression damping knob does not require tools; rebound adjustments are standard as well. We advanced mountain sled design for easier and more predictable handling in all conditions. The narrow body panels, bottom pan, tunnel and running boards are designed for optimal interface with snow in mountain maneuvers. An open tunnel end eliminates drag. Snow passes easily through the extruded grid-style board preventing washout and trenching, plus clears footrests for grip. Flatter foot position for comfort and control. .75 in. / 20mm higher than REV-XM. The tMotion flexes laterally, reducing the effort to initiate a roll, due to a ball joint at the center hinge between the rear arm and drop link and split flat-tube front arms. Very progressive motion ratio makes the ride on trails even more comfortable. Precise, predictable handling and outstanding bump absorption, even in harsh conditions, with State-of-the-art unequal length A-arm front suspension.
