MAIN 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 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.

BREED OF POWER

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.

CONFIDENCE-INSPIRING HANDLING

AWS 42 FRONT SUSPENSION WITH PROGRESSIVE RATIO STEERING

The AWS 42 Front Suspension is engineered specifically to compliment the EXT Special. With ratio steering to reduce rider effort, you'll experience more control.

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.

NAVIGATION AT YOUR FINGERTIPS

ARCTIC CAT G8 DIGITAL DISPLAY

The all new 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.

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.

Intuitive Handling

Power Steering

As an Arctic Cat exclusive, Electronic Power Steering (EPS) on a 2-stroke snowmobile is a next-level experience. Unmatched control, easier turns, and intuitive handling will upgrade your ride more than you could imagine.

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.

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.
