Features May Include:

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.

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.

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.
