MXZX-RSMXZ X-RS 850 E-TEC

Based on our factory MXZ X race sled for riders who want the ultimate capability in an aggressive trail sled.

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: Created with the Rotax 850 E-TEC engine to be the ultimate handling trail snowmobile. The 4th generation of the REV Gen4 platform is designed around aggressive trail riders with a narrow, compact package giving the rider more freedom to move and influence the sled. More centralized masses (especially side-to-side), light weight and industry-leading suspensions make the vehicle ultra responsive.
  • PDRIVE CLUTCH: 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.
  • RS RUNNING BOARDS: Designed for aggressive stand-up riding, they are flatter for most of their length, wider and strong. Thicker aluminum sheet (3 mm vs. 1.8 mm), plus front and rear reinforcements to withstand tough landings.
  • RMOTION 129 REAR SUSPENSION: THE standard for control, capability, comfort and adjustability – with added traction, better braking and more bump filtration in 129-inch (327 cm) 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.
  • RAS 3 FRONT SUSPENSION: 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 (3,2 kg) reduced weight vs. RAS 2. Even more precise with rack steering system that eliminates all bump steer.
  • ADJUSTMENT PACKAGE (OPTIONAL) (SPRING ONLY): This option includes rMotion Quick Adjust system with no-tool tuning of the rear spring preload and shock compression damping on the running boards and new Pilot TS adjustable skis.
  • ERGO-STEP SIDE PANELS: Design enables you to slide naturally to three different cornering styles, including a new, extreme-forward position.
  • KYB PRO SHOCKS: These shocks are standard on the MXZx 600RS race sled - so you know they're extremely capable and durable for control in the toughest conditions. Remote reservoir design for performance and they are a rebuildable/revalvable. Easy Adjust compression damping knob does not require tools; rebound adjustments are standard as well.
  • X-RS FEATURES: Designed for the toughest terrain racing, the X-RS package includes special features. The steering post is more forward for the most aggressive cornering and stand-up riding position. And the suspension rails and running boards are reinforced for tough landings.
