ALL NEW 858 ENGINE

With an 8% increase in displacement, this engine houses an 11% increase in output over the C-TEC2 800 and weighs 4% less.

UNMATCHED CONTROL

ALPHA ONE Single-Beam Rear Suspension

The unique monorail design sheds snow to keep your sled light and equalizes floatation across the width of the track. ALPHA ONE offers enhanced maneuverability, giving you tighter turns than ever before.

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.

EFFORTLESS SUPPORT

IFP Shocks

You’ll feel the difference in every ride with premium, internal floating piston (IFP) shocks. These shocks will dampen the roughest terrain and offer increased durability, allowing you to maximize your deep snow performance.

QUICKLY CONNECT

ATACH Latching System

Adding accessories to your sled is a snap with this all-new 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.

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.

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.

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, 154-in and 165-in with 2.6-in or 3.0-in lugs.

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 it’s unique asymmetrical design, everyone will know that you’re on an Arctic Cat.
