Breed of Power
858 Engine
The 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.
Speed, Power A and Agility
The CATALYST™ platform transformed the experience of mountain, trail and crossover riders alike. Now with the refined 858 engine, you can push the limits even further with bigger power, smoother performance and the industry’s easiest-to-ride package.
Purpose-Built
Based on decades of innovation, the 858 engine was built by Arctic Cat for Arctic Cat. Designed specifically for the CATALYST platform, the 858's proprietary design enhances power, agility and control. From working around the centerline steering to integrating components for weight reduction and increased performance, no compromises were made in pursuit of the ultimate ride.
Peak Performance
The 858cc engine provides all the horsepower and airflow you need for superior performance. A refined air intake system improves sealing at the lower airbox, reducing snow intrusion and maximizing consistency. Multiple under-hood inlets prevent snow ingestion, while our patented exhaust valve design stays tight to the piston as it moves. This delivers smoother exhaust flow through a wider RPM range on both primary and auxiliary ports — and cleaner emissions in all conditions.
Quicker Acceleration
Compared to Arctic Cat’s 794cc engine, the 858 delivers 11% more power and torque — and in a package that’s 4% lighter. This gives you an optimal power-to-weight ratio for quicker acceleration and a more responsive, pulse-pounding ride. Arctic Cat used an 85mm bore while increasing to a 75.6mm stroke to achieve more horsepower and deep, bottomless torque that pulls hard and smoothly through the entire RPM range. In MY26, recalibrated fueling and ignition enhance response across more of that range, making every squeeze of the throttle feel even more connected.
Greater Agility
The centralized mass and low center of gravity work with the CATALYST platform to provide precision and control unlike anything you’ve experienced. The innovative laydown engine design achieves the best mass centralization of any snowmobile on the market while staying lightweight and compact. And with updated engine mounting in MY26, vibration is further reduced — boosting rider confidence and comfort mile after mile.
Easy Maintenance
The CATALYST platform was designed to be durable and easy to service, and the 858 engine is no exception. With fewer parts, a revised crankcase mounting system, it’s stronger, sturdier and easier to maintain. With the easily removable, completely tool-less plastic panels on CATALYST snowmobiles, you can quickly access critical components to admire the beauty beneath the surface. There's even a robust snow flap reinforcement

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 celluar data, dependent on region, to share the ride with up to 15 people.
Aws 42 Front Suspension with Progressive Ratio Steering
AWS 42 is the culmination of over 40 years of experience with the Arctic Wish Suspension, optimized for trail riding. By centralizing the weight distribution, the suspension now sits directly under the rider, giving them more flexibility to move around on the sled, as well as giving them more control. This also puts more of the sled's weight on the skis, improving balance.
With a progressive steering ratio, riders will feel the difference immediately. The sled will react to the slightest movement, making the ZR 600 feel like a natural extension of the rider's body.
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.
Slide-Action™ Rear Suspension
Unlock the true potential of a coupled suspension with our unique SLIDE-ACTION design. The front arm fits into a U-shaped slot that allows 0.5 inches of sliding movement, so the front arm won’t collapse whenever the rear arm compresses. That unique design gives you the full benefit of coupling: controlled ski lift during acceleration and the complete use of the front arm at all times. SLIDE-ACTION suspension also allows a lower and more consistent track tension with its Torque-Sensing Link, plus three-position rear coupling block adjustability, adjustable spring preload and a durable 3-wheel rear axle assembly.
Fox® Zero IQS Shocks
ATAC Adjustable On-the-Fly's FOX® ZERO shocks feature piggyback reservoirs, three compression settings and two custom suspension settings with an electronic control system designed and developed with Arctic Cat Technology.
Three Factory Suspension Settings
Whatever terrain you face, the soft, medium and firm suspension settings guarantee you the perfect ride.
Two Customizable Driver Profiles
Dial in your ride more precisely than ever before with advanced settings that let you fine-tune the ratio of control between the ski shocks and rear track shocks. ATAC can remember two driver profiles with their own personalized settings.
Digital Display
Get an instant read on which firmness setting you’ve selected — soft, medium or firm — from the digital instrument gauge.
Convenient Push-Button Control
No more getting off your snowmobile to dial in a new compression setting. ATAC makes it easy to shift between suspension settings with just the push of a handlebar-mounted button.
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.
Narrow Design Like No Other
The ADAPT CVT system's narrow design reduces engine strain and improves under hood accessibility, providing a superior experience.
Lightweight and Efficient
With its lightweight design, the ADAPT CVT System decreases rotating mass while giving you improved throttle response and enhanced power delivery.
Consistent Performance
The ADAPT CVT System features an idler bearing that maintains constant belt tension and keeps temperatures down. This offers smoother takeoffs and rides throughout the life of the belt by automatically adjusting to wear.
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.
Lock in with Ease
All CATALYST platform models come factory-equipped with at least two mounting points for ATACH accessories. Installation is quick and easy: simply slide your accessory into place with a click. You won't need any modification, fasteners or tools.
Durable Design
ATACH is built for the harshest conditions. This rugged system is built with high-strength composite and utilizes dust covers to keep the system clean when not in use.
Keep It SAFE
Your accessories are safe when installed with the ATACH 4-Point Latching System. Using the provided key, you can lock your accessories onto your sled to prevent theft. Even if you choose not to use the theft-prevention lock, your accessories will remain securely attached to your sled.
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.
