A New Breed of Power Is Here

The CATALYST™ platform transformed the experience of mountain, trail and crossover riders alike. Now with the 858 engine, you can push the limits even further with bigger power in the industry's easiest to ride package.

  • 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. 

  • The 858cc engine provides all the horsepower and airflow you need for superior performance. The air intake system maximizes airflow for more power output while multiple secondary, under-hood inlets prevent snow ingestion for optimized performance in all conditions. Our newly patented exhaust valve design also stays tight to the piston as it moves. This creates smoother exhaust port flow through a wider RPM range on both primary and auxiliary ports — and cleaner emissions. 

  • Compared to Arctic Cat's 794cc engine, the 858 provides 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. To keep a lightweight, compact size for the CATALYST platform, Arctic Cat used an 85mm bore while increasing to a 75.6 stroke to achieve more horsepower and deep, bottomless torque that pulls hard and smoothly through the entire RPM range. The result is a power-dense, easier to ride package that takes carving through deep snow, maneuvering tight trails and boondocking to the next level. 

  • 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. The result is a powerful, easy-to-ride sled. 

  • The CATALYST platform was designed to be durable and easy to service, and the 858 engine is no exception. With fewer parts and an integrated mounting design in the crankcase, 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. 

Explore the CATALYST Platform

We built it from the skis up to give you a completely new riding experience. Use this interactive tool to explore the features that make the CATALYST platform the ride you've been waiting for.

Calibrated Suspension

The CATALYST platform takes a centralized design ideal for all riding styles and pairs it with legacy suspension and steering to provide a unique experience for each segment. In the trail and crossover families, the driveshaft and the front and rear suspension have been positioned further rearward to optimize sled balance and increase ground clearance. By lowering the upper A-arms and shortening the spindles, this new design will give you a more position-reactive vehicle with improved cornering. With ratio steering paired with progressive steering, this innovative design offers a lighter, tighter feel that uses leverage first to mimic the feeling of power steering.

On the mountain side, the driver position is optimized for flotation. The lower center of gravity on the CATALYST platform works in tandem with the rider to improve climbing, carving and descent. It also features centerline vertical steering for a lighter, more responsive experience. This is achieved by integrating the new intake, exhaust and chassis. Moreover, the new spindles and front suspension have both been optimized for off-trail maneuvers while remaining capable on-trail.

Laydown Engine

The narrow, tightly compacted and completely balanced CATALYST platform features Arctic Cat’s exclusive laydown engine design for both the new 858 and 600 engines. This design allows us to position the engine closer to the ground, lowering the sled’s center of gravity for optimal stability you’ll feel in every ride.

Lower Center of Gravity

By starting from the middle and centralizing the heaviest components in the CATALYST platform, Arctic Cat engineers have designed a more reactive design that requires less rider effort than ever before. Everything about this platform is optimized to keep the weight centralized and balanced, from the exclusive laydown engine design to the innovative and narrow ADAPT CVT system. The shape of the 10.4-gallon gas tank contributes to this unprecedented design while providing aggressive ergonomics and maintaining constant fuel pickup.

ATACH™ Accessory System

The CATALYST platform has the first built-in accessory system with key locks for securing a variety of bags and accessories onto your sled. No unsightly rivets or bolts here. ATACH™ is seamlessly integrated, easy to use and totally secure. This is just the beginning — look for more new accessories to be added to the system soon.

Reengineered Chassis

An ultra-high-strength steel, one-piece chassis with an aluminum tunnel provides rock solid support and industry leading durability while also delivering an optimized, compact design for improved packaging and ergonomics. The chassis, refined through extensive FEA and real-world durability testing, contributes to CATALYST’s lightweight mass-centralized design. New high-strength lightweight one piece tunnels compliment the front chassis and composite components for an unmatched rider experience. This results in strong, more efficient components that are easier to service.

Ease of Service

The robust new belt drive system enhances performance with fewer parts, making maintenance simpler than ever before. With an adjustable center distance for multiple gearing options, even belt replacement is simplified. Accessing different sections of your sled is painless with the CATALYST chassis: the plastic panels’ tool-free design allows quick access to components like the belt, oil reservoir and coolant. You can also access the battery with a quarter turn of the seat.

Redefined Ergonomics

The narrowed sled design and optimized shape of the gas tank gives you more maneuverability, agility and comfort when riding a sled with the CATALYST platform. With revised body panels, a tapered tunnel and more, this platform creates an idealized rider interface. You’ll experience less rope wear with the new recoil rope routing. The redesigned running boards and composite toe stops, which have been optimized for each segment, will decrease vibrations in your feet. Coupled with the centralized design, these ergonomic updates will minimize rider fatigue, giving you more confidence and control of your ride.

10% Weight Reduction

Equipped with fewer parts, lighter seats, a completely redesigned intake configuration and many more weight reducing components, the CATALYST platform brings a drastic 10% weight reduction to the trail, crossover and mountain segments. The ADAPT CVT system and the fastener reduction contribute to this weight reduction, and the new belt drive system weighs less than half the weight of the current chain drive system.

Engine Availability

The powerful new 858 engine was built by Arctic Cat, specifically for the CATALYST platform. In addition to its low center of gravity, the 858 works around the centerline steering while integrating components for weight reduction — increasing agility and performance — so you get a faster, zero-compromise ride every time. Complementing this high-performance option is our proven C-TEC2™ 600, 2-stroke engine. Tightly packed by a proprietary exhaust with the airbox up front and positioned low to the ground, it ensures incredible stability, delivering a ride that's just as exhilarating.


Each CATALYST snowmobile is designed and optimized to meet your specialized performance, handling and balance needs. With the choice of the 858 or 600 engines, it’s easy to find the perfect sled for any mountain, trail or crossover ride.
