VERSATILITY MEETS VELOCITY

Features may include:

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.

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.

CONFIDENCE-INSPIRING HANDLING
  • 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.

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.
