Features

RIDE. REPEAT. NO REST REQUIRED.
ELECTRONIC POWER STEERING

Electronic Power Steering (EPS) allows you to extend your ride time with a smoother experience through less bar movement, less trail feedback and less impact. Discover why EPS isn’t just a nice-to-have — it’s vital for unlocking more ride time and ride quality, regardless of your experience level.

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.

PURPOSE-BUILT POWER
858 ENGINE

Push the limits with a strong, responsive output across the full RPM range with a consistent pull you can feel. The 858 two-stroke EFI engine is designed for seamless integration with the Arctic Cat CATALYST platform. Patented exhaust valves and a sealed intake system maximize airflow and throttle response, while a purpose-built design reduces weight. All resulting in a compact, durable package built to perform season after season.

ULTIMATE ADJUSTABILITY
AC5S SHOCKS

Meet our anything-but-stock shocks. AC5S ski, front and rear track shocks are designed and calibrated at Arctic Cat for Sno Pro sleds and feature a unique color scheme. The 5-position adjustment with adjustable spring preload gives you even more flexibility to finetune your ride.

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 progressive-ratio steering to reduce rider effort, you'll experience more control.

NO ROUGH RIDES
SLIDE-ACTION™ REAR SUSPENSION

The industry-exclusive SLIDE-ACTION rear suspension design keeps the front arm engaged while the rear arm compresses, so you'll hardly feel a bump in the trail.

UNMATCHED HANDLING
RIPSAW™ II TRACK

The Ripsaw II Track features angled 1.25-inch lug engineered for confident handling and quick acceleration. With a 137-in length, it delivers added stability and control across both firm and looser conditions.

NAVIGATION AT YOUR FINGERTIPS
G8 DIGITAL DISPLAY

 The 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 cellular data, dependent on region, to share the ride with up to 15 people.
