• A BREED OF POWER - 858 ENGINE: The 858 two-stroke engine is designed for seamless integration into the 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 exhaust valve design for more consistent power and cleaner emissions, and an 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 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.

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.
