2019 Ski-Doo Summit X 154 850 E-TEC ES PowderMax Light 2.5 H_ALT

Features

• 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.
• REV GEN4 PLATFORM: Key to the Summit’s agility is the extreme mass centralization of the 4th generation REV platform. The 850 E-TEC engine is compact and centered between the skis, making the vehicle easy to roll. The trademark pyramidal frame, new die-cast aluminum front suspension module and new heat exchanger design ensure it’s strong, yet lightweight.
• PDRIVE CLUTCH: 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% 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.
• TMOTION REAR SUSPENSION: 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.
• POWDERMAX LIGHT TRACK WITH FLEXEDGE: 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.
• MOUNTAIN-SPECIFIC DESIGN: 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.
• PROFILE RUNNING BOARDS: 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)
• RAS 3 FRONT SUSPENSION: Similar geometry and design to the stable and precise RAS 2, optimized for the Gen4 REV platform with 1 in./25mm added suspension stroke and .7 lbs (0.3 kg) reduced weight vs. RAS 2.
