2018 Ski-Doo MXZ X-RS 600 E-TEC Iron Dog


You don’t have to be a racer to appreciate the incredible big bump capability and cornering precision of the Ski-Doo MXZ X-RS 850 E-TEC model. It's the perfect sled for an intense Sunday run over rutted out trails.


  • IRON DOG-INSPIRED FEATURES: For incredible capability, there’s a two-ply RipSaw track and extra suspension reinforcements front and rear directly from the factory race sleds,plus KYB Pro 40 shocks, tuned for even more capability in big bumps than the MXZ and Renegade X-RS models. All the suspension springs go one step stiffer, with the center shock using a dual rate spring.
  • REV-XS RS PLATFORM: Same chassis used on the MXZ X 600RS race sled, including most reinforcements and wide, strong running boards with extruded edge. The REV-XS body style has a more aggressive cornering position, added wind protection, glove box and more. Layered flowing edge styling delivers exceptional fit and finish. The steering post can be moved forward to create a very aggressive position for stand-up riding.
  • RMOTION 129 REAR SUSPENSION: THE standard for control, capability, comfort and adjustability – with added traction, better braking and more bump filtration in 3269 mm (129-in.) version. Separate spring and shock dynamics, plus the most rising-rate/progressive motion ratio in the industry give the rMotion suspension its supple ride in small bumps with added capability in large ones. Easy adjustments for shocks, springs and coupling block.
  • PILOT 5.7 SKIS: Dual-keel/single-carbide design for aggressive bite in corners and virtually no darting.
  • ROTAX 600 H.O. E-TEC ENGINE: The 600 cc-class benchmark for fuel economy, oil economy, smoothness and ease-of-use. Up to 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.
  • MULTI-FUNCTION ANALOG / DIGITAL GUIDE: Sharply-styled analog speedometer and tachometer are complemented by a multi-function three-zone LCD screen packed with data.
