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.

QUICKLY CONNECT

ATACH Latching System

Adding accessories to your sled is a snap with this all new 4-point latching system. You can install and remove accessories in seconds, so no matter where you are, you can customize your sled with ease.

SMOOTH POWER DELIVERY

ADAPT CVT SYSTEM

With its lightweight, narrow design that increases performance and belt life, as well as the industry’s only self-adjusting clutch, the ADAPT™ CVT system provides better throttle response, smoother power delivery and a ride like no other.

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.

PLAYFUL COMFORT

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.

INCREASED DURABILITY

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.

CONFIDENCE-INSPIRING HANDLING

AWS 39 FRONT SUSPENSION WITH PROGRESSIVE RATIO STEERING

AWS 39 is the culmination of over 40 years of experience with the Arctic Wish Suspension, optimized for crossover versatility. By centralizing the weight distribution, the suspension now sits directly under the rider giving them more control and flexibility to move around on the sled. This also puts more of the sled's weight on the skis, improving balance.

With a progressive steering ratio, riders will feel the difference immediately. The sled will react to the slightest movement, making the Riot 600 feel like a natural extension of the rider's body.

BRIGHTEN ANY RIDE

ASYMMETRICAL LED HEADLIGHT

A premium LED headlight is crucial to optimize your visibility. Equipped with both high and low beams, this headlight casts an LED light pattern with great range and width. Plus, with it's unique asymmetrical design, everyone will know that you're on an Arctic Cat.

READY TO GO

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.
