2018 Ski-Doo Expedition Xtreme 800R E-TEC


The meanest and fastest sport-utility snowmobile ever offered, with Rotax 800R E-TEC engine and premium KYB shocks.


  • ROTAX 800R E-TEC ENGINE: Direct-injection technology mill pumps out big power while delivering up to 19 mpg (12.3 L/100 km) fuel economy. Excellent oil consumption, plus easy throttle pull, linear power delivery and virtually no smoke or smell. Proven and recognized by riders for reliability. Preparing for the off-season is easy with built-in automatic summerization function.
  • HPG PLUS R FRONT SHOCKS: Lightweight and very capable aluminum shocks by KYB. Wide range of adjustability with rebound damping adjustment and rebuildable/revalvable design.
  • KYB PRO 36 REAR SHOCK: Race-proven aluminum shock with no-tool compression damping adjustment. Rebuildable/revalvable design.
  • SC-5U REAR SUSPENSION: Our sport-utility suspension. Refined ride both on trail and on top of powder. Articulated rail to maximize deep snow traction in reverse or locked out when towing.
  • 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.
  • REV-XU PLATFORM: This base architecture and design sets the standard for light weight, durability and handling. Flexible riding position enables comfort sitting and standing. Driver can stretch their legs due to forward foot position. Cab and bottom pan shapes are optimized for flotation and snow flow. Styling is rugged and dynamic.
  • PILOT DS 2 SKIS: Single-keel with excellent sidehilling bite, thanks to thin outer edges. Narrow and thin, yet stiff. Shorter behind its complementary spindle with flat tail for easier counter-steering and sidehilling.
  • 20 x 154 x 1.75 TRACK: Added traction for off-trail play.
  • SYNCHROMESH TRANSMISSION: Take off from a stop smoothly, even with a heavy load, thanks to two forward and one reverse gears. Inline 2-1-N-R pattern on right side and can be safely shifted from High to Low while on the fly.
  • ALUMINUM RACK: Delivers 55 pounds (25 kg) of cargo capacity.
