Features may include:

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.

Intuitive Handling
  • Power Steering

As an Arctic Cat exclusive, Electronic Power Steering (EPS) on a 2-stroke snowmobile is a next-level experience. Unmatched control, easier turns, and intuitive handling will upgrade your ride more than you could imagine.

Navigation at your Fingertips
  • Arctic Cat G8 Digital Display

The Arctic Cat G8 digital display, powered by Garmin, offers seamless integration with your sled. A built in GPS with preloaded trail maps, customizable data fields and phone connectivity are just some of the features that make G8 essential for every ride. Plus, the group ride functionality utilizes satellite or celluar data, dependent on region, to share the ride with up to 15 people.
