Features

Features

  • A BREED OF POWER - ALL 858 ENGINE: The 858 two-stroke engine is designed for seamless integration into the 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 exhaust valve design for more consistent power and cleaner emissions, and an all 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 at one with the sled. With enhanced ergonomics, a lower center of gravity, our exclusive laydown engine design, specially calibrated suspension and more, this changes everything.
  • NAVIGATION AT YOUR FINGERTIPS - ARCTIC CAT G8 DIGITAL DISPLAY: The all Arctic Cat G8 digital display, powered by Garmin, offers seamless integration with your sled. A built in GPS with preloaded trail maps, customizable data fields and phone connectivity are just some of the features that make G8 essential for every ride. Plus, the group ride functionality utilizes satellite or celluar data, dependent on region, to share the ride with up to 15 people.
  • CONFIDENCE-INSPIRING HANDLING - AWS 42 FRONT SUSPENSION WITH PROGRESSIVE RATIO STEERING: The AWS 42 Front Suspension is engineered specifically to compliment the ZR 858. With ratio steering to reduce rider effort, you'll experience more control.
  • VERSATILE SUSPENSION - ATAC® ADJUSTABLE ON-THE-FLY SUSPENSION: The ATAC Adjustable On-the-Fly Suspension immediately adjusts the FOX® ZERO iQS shocks with the push of a button to navigate changing snow conditions. Choose between two rider profiles, three firmness settings and engage lockout mode to ride your way.
  • 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 utilizes Arctic Cat's belt drive system rather than a chain drive. This allows for enhanced durability and fewer parts in the system. The adjustable center distance allows for multiple ratio options and makes servicing simple.
  • 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.
  • 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.
  • 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.
