Features

Features

  • 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.
  • LIGHTWEIGHT BUT POWERFUL - 600-SERIES C-TEC2 ENGINE: This robust, yet lightweight 599cc, 125-HP C-TEC2™ engine with Dual-Stage Injection (DSI) offers more than enough power to conquer the trails, while keeping the sled feeling weightless.
  • 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.
  • INCREASED DURABILITY - ARCTIC CAT TRAIL BELT DRIVE: The CATALYST platform utilizies Arctic Cat's belt drive system rather than a chain drive. This allows for enahnced durability and fewer parts in the system. The adjustable center distance allows for multiple ratio options and makes servicing simple.
  • 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.
  • QUICKLY CONNECT - ATACH LATCHING SYSTEM: Adding accessories to your sled is a snap with this 4-point latching system. You can install and remove accessories in seconds, so no matter where you are, you can customize your sled with ease.
  • READY TO GO - ELECTRIC OR MANUAL START: The convenience of electric start is just one of the countless things that sets the ZR 600 R-XC apart. With just the push of a handlebar-mounted buttonyou’ll be up and moving. If you’re looking to drop even more weight from this already lightweight sled, you can also opt for a manual starter.
  • BRIGHTEN ANY RIDE - ASYMMETRICAL LED HEADLIGHT: A premium LED headlight is crucial to optimize your visibility. Equipped with both high and low beams, this headlight casts an LED light pattern with great range and width. Plus, with its unique asymmetrical design, everyone will know that you're on an Arctic Cat.
