Re-Inventing Mountain Riding
Mountain 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.
Features May Include:
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. 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.
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.
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.
