2018 Ski-Doo Summit SP 146 600 H.O. E-TEC ES


With signature mountain technologies like REV-XM platform, tMotion rear suspension, and FlexEdge tracks, the Summit SP can carve lines you never thought possible.


  • REV-XM PLATFORM: Summit-specific side panels are powder dynamically designed to glide smoothly through snow in any position, easing roll-up and sidehilling.
  • 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.
  • FLEXEDGE TRACKS: By shortening the fiberglass reinforcing rods inside, the track’s edges flex when you carve the sled, making boondocking and sidehilling easier. Provides the flotation of a 16-in. (41 cm) wide track with the agility of a 12-in. (30 cm) track.
  • ROTAX 600 H.O. E-TEC ENGINE: The 600 cc-class benchmark for fuel economy, oil economy, smoothness and ease-of-use. Up to 21 mpg (11.3 L/100 km) trail fuel economy. Virtually no two-stroke smoke and smell and easy starting. Preparing for the off-season is easy with built-in automatic summerization function. No wonder it’s the best-selling 600cc engine in snowmobiling*. 120 horsepower. *Based on retail sale results as of December 31, 2016.
  • RAS 2 FRONT SUSPENSION: Ultimate geometry and lighter components deliver excellent precision and stability – especially in extreme bumps – and reduces roll in corners. Sharp styling, too.
  • PILOT DS 3 SKIS: Designed to work in tandem with the deeper and longer 3 in. track lugs. It has a .47 in (12mm) deeper keel. Holds a sidehill better and offers great control. Narrow ski tip cuts through crusty shallow snow; wide easy-to-install extension widens the tip for added flotation in deeper powder. Pilot DS 2 Skis with Summit SP 146 sleds
  • REV-XM RUNNING BOARDS: Massive, strategically shaped openings keep the boards clear. A tall extruded edge adds stiffness and has aggressive boot grips.
  • MULTIFUNCTION ANALOG / DIGITAL GAUGE: Sharply-styled analog speedometer and tachometer are complemented by a multifunction three-zone LCD screen packed with data.
  • REV-XM COCKPIT: We designed the cockpit around mountain riders: the gauge is mounted flat, switches are moved to the console, buttons are shielded from accidental activation and the grab handle is rigid and shaped to your hand. Every surface of the seat is sculpted for powder riding gymnastics.
