The 2019 Summit X changes the mindset of a deep snow rider with its effortless deep-snow agility, and instant power. It dares you to leave nothing on the table each and every ride - and rewards you every time you do.


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 advanced 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.


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 Summit’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 advanced 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.


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.


New 3.5 in. (9 cm) pitch reduces weight, and keeps snow between lugs for added performance. Exclusive 16-in (41-cm) wide design adds flotation and traction without sacrificing manoeuvrability. Edges flex to reduce the effort to initiate roll-up. Available in either 2.5 or 3.0 in (6.3 or 7.63 cm) lug heights.


Striking Lava Red glossy coloration with high-end protective panel wrap to resist scratches and blemishes keeps your sled looking showroom ready.


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. (X-package only)


Precise, predictable handling and outstanding bump absorption, even in harsh conditions, with state-of-the-art unequal length A-arm front suspension.
