2018 Ski-Doo MXZ X-RS 850 E-TEC

Description
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.
-
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.

NEXT GENERATION OF A LEGEND
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.
-
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.

ROOM TO ROAM
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.
-
CAPABILITY, CONTROL AND COMFORT
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.
-
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 (3,2 kg) reduced weight vs. RAS 2. Even more precise with rack steering system that eliminates all bump steer.
