2018 Ski-Doo SUMMIT SP 850 E-TEC
The agile, powerful and effortless Summit SP is built around the rider more than ever before to make even the most technical boondocking easier for riders of every ability.
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.
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.
NEXT GENERATION OF A LEGEND
Key to the Summit’s agility is the extreme mass centralization of the 4th generation REV Gen4 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.
QUICK, EFFICIENT, EASY
A major factor in the quickness of REV Gen4 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.
CARVES WITH YOU
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.
HEAVY ON PERFORMANCE
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.
YOU'RE AT THE CENTRE
We designed the new Summit to enable you to do more with less effort. The narrow body, beveled tunnel, tank, seat and handlebar controls are extremely compact and narrow for more room to move. And your legs will appreciate the flatter foot position.
DESIGNED FOR THE MOUNTAINS
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.
PRECISION FRONT END
Similar geometry and design to the stable and precise RAS 2, optimized for the REV Gen4 platform with 1 in./25mm added suspension stroke and .7 lbs (0.3 kg) reduced weight vs. RAS 2.
