Mountain Riding Reinvented

Features may include:

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.

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.

ULTIMATE ADJUSTABILITY
  • AC5S SHOCKS

Designed by Arctic Cat, for Arctic Cat, the all new AC5S shocks offer 5 different positions and adjustable spring preload. They are uniquely calibrated for backcountry riding and showcase both Arctic Cat's legacy of durability and its signature style.

OPTIMIZED FOR DEEP SNOW
  • AWS 36 FRONT SUSPENSION

The AWS 36 Front Suspension was designed specifically with the M 858 in mind. With lightweight spindles and precision engineered geometry, this suspension system optimizes your performance in deep snow.

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.
