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.

UNMATCHED CONTROL
ALPHA ONE SINGLE-BEAM REAR SUSPENSION
Arctic Cat’s revolutionary single-beam rear suspension changes the game for mountain snowmobiles. The unique monorail design sheds snow to keep your sled light and equalizes floatation across the width of the track. ALPHA ONE offers unmatched maneuverability and flotation – allowing you effortlessly go where others are left stuck and tired.

OPTIMIZED FOR DEEP SNOW
AWS 36 FRONT SUSPENSION
The AWS 36 Front Suspension was designed specifically with the M 600 in mind. With lightweight spindles and precision engineered geometry, this suspension system optimizes your performance in deep snow.

KEEP YOURSELF PLANTED
Twin Rail Suspension
The twin rail braced suspension is built for one thing: carving and climbing with control. With two braced rails, it delivers a solid, predictable feel that keeps the track straight and the power locked in — even when the hill gets rutted, windblown or near vertical. Compared to single rail setups, it’s less flickable but more planted — perfect for riders who’d rather hold the line than play around it.

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.

A NEW 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.

UNPRECEDENTED TRACTION
POWER CLAW TRACK
Unlock the backcountry with Power Claw™, a lightweight track that delivers the ultimate deep snow traction and performance. The staggered, forward curving paddle tower design won’t fold over, allowing you to float over the deepest snow. Available in 146-in and 154-in with 2.6-in or 3.0-in lugs.

INCREASED DURABILITY
ARCTIC CAT MOUNTAIN 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. Additionally, the track included with the AC Mountain Belt Drive ensures that the sled gets up on the snow quicker, avoiding trenching issues.

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.
