MASTER THE TRACK

The R-XC you know and love just got a major upgrade. This race-winning sled is ready to blaze new trails with the revolutionary CATALYST chassis.

Features may include:

A NEW BREED OF POWER
  • ALL NEW 858 ENGINE

The all-new 858 two-stroke engine is designed for seamless integration into the new CATALYST platform. With an 8% increase in displacement, this engine houses an 11% increase in output over the C-TEC2 800 and weighs 4% less. It features an optimized air intake system, a new exhaust valve design for more consistent power and cleaner emissions, and an all-new crankcase for increased stroke and integrated engine mounts.

PEAK PERFORMANCE UNLOCKED
  • CATALYST CHASSIS

The revolutionary CATALYST platform has been built from the ground up to optimize every aspect of your ride, so much so that you’ll feel like you’re one with your sled. With enhanced ergonomics, a lower center of gravity, our exclusive laydown engine design, specially calibrated suspension and more, this changes everything.

CONFIDENCE-INSPIRING CONTROL
  • AWS 42 FRONT SUSPENSION WITH PROGRESSIVE RATIO STEERING

The AWS 42 Front Suspension is engineered specifically to compliment the ZR and ZR R-XC. With ratio steering to reduce rider effort, you'll experience more control.

UNRIVALED SUPPORT
  • FOX® ZERO QS3 SHOCKS

These lightweight shocks are designed to move comfortably and adjust easily, offering you a plush ride with enhanced control. They easily neutralize any bumps in the trail, bringing out a snowmobile experience like no other.

NO ROUGH RIDES
  • SLIDE-ACTION™ REAR SUSPENSION

Rough rides are a thing of the past. With this industry-exclusive design that keeps the front arm engaged while the rear arm compresses, you'll hardly feel a bump in the trail.

SMOOTH POWER DELIVERY
  • ADAPT CVT SYSTEM

With its lightweight, narrow design that increases performance and belt life, as well as the industry's only self-adjusting clutch, the ADAPT CVT system provides better throttle response, smoother power delivery, and a ride like no other.

READY TO GO
  • PUSH-BUTTON ELECTRIC START

The convenience of electric start is just one of the countless things that sets the ZR apart. With just the push of a handlebar-mounted button you’ll be up and moving.
