Re-Inventing Mountain RidingMountain riding just got a lot more interesting. The Arctic Cat M ALPHA ONE will revolutionize how you explore the backcountry with the groundbreaking CATALYST platform.

A NEW BREED OF POWER- ALL NEW 858 ENGINE
The all-new 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.

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 858 in mind. With lightweight spindles and precision engineered geometry, this suspension system optimizes your performance in deep snow.
