2025 Arctic Cat® Riot 858 146"/1.35" Cobra

Why choose between the thrills of on-trail riding and the adventure of venturing into the deep snow when you can have both? Riot blends trail and backcountry performance seamlessly for the ultimate adaptable ride.

Features may include:

• 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.

• 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.

• AWS 39 FRONT SUSPENSION WITH PROGRESSIVE RATIO STEERING

The AWS 39 Front Suspension is engineered specifically to compliment the Riot 858. With ratio steering to reduce rider effort, you'll experience more control.

• CROSS-ACTION REAR SUSPENSION

The uncoupled CROSS-ACTION rear suspension provides unparalleled agility from powder to hardpack. The design enables the front and rear halves of the suspension to move independently, so riders enjoy excellent cornering and bump absorption on the trail, as well as off-trail weight transfer.

• IFP SHOCKS

You’ll feel the difference in every ride with premium, internal floating piston (IFP) shocks. These shocks will dampen the toughest terrain and offer increased durability, allowing you to maximize your performance.

• ARCTIC CAT TRAIL BELT DRIVE

The CATALYST platform utilizies Arctic Cat's belt drive system rather than a chain drive. This allows for enahnced durability and fewer parts in the system. The adjustable center distance allows for multiple ratio options and makes servicing simple.

• PUSH-BUTTON ELECTRIC START

The convenience of electric start is just one of the countless things that sets the Riot apart. With just the push of a handlebar-mounted button you’ll be up and moving.It is also equipped with a backup manual starter.
